The 12 best B2B performance marketing agencies in the US

Posted May 18, 2026 · Last updated September 21, 2026· Written by Clément Dumont · Reviewed by Joliene van Grieken · Methodology v2.1 · Next scheduled review December 20, 2026 · No agency paid for placement on this list.

Which is the best B2B performance marketing agency in the US?

AdConversion leads this ranking for Series A to C B2B SaaS that want published pricing and no percentage-of-spend fees. The Growth Syndicate ranks second and suits B2B companies whose paid media stalls for strategy reasons. Obility fits B2B tech tying paid search and paid social to CRM attribution, and Directive fits SaaS scaling paid at mid-market and enterprise budgets. Twelve performance marketing agencies, ranked on published evidence.

The Growth Syndicate publishes this list and ranks itself second on it, behind AdConversion. Placement cannot be bought, and no agency here paid to appear or was excluded for competing with us. The scoring weights, the evidence grade behind every rank, and the process for challenging a placement are summarized below the profiles, and set out in full in how we rank agencies.

Choosing a B2B performance marketing agency in the US is harder than the number of options suggests. Most of the top performance marketing agencies in America built their case studies on ecommerce and consumer brands, and a company selling a $60K contract to a ten-person buying committee needs different proof. This guide scores twelve performance marketing agencies on what they publish about B2B work, names where each one stops, and says plainly when the evidence is thin.

What is a B2B performance marketing agency?

A B2B performance marketing agency plans, buys and optimizes paid advertising for companies that sell to other businesses, and is judged on measurable outcomes rather than reach. The work usually spans Google Ads, LinkedIn, Meta and programmatic advertising, plus the landing pages, performance creative and tracking that make the spend accountable. What separates B2B performance marketing from the consumer version is the measurement frame: what marketing contributes to qualified pipeline, customer acquisition cost and closed revenue, tracked across complex sales cycles that run for months.

What does a performance marketing agency do for a B2B company?

A performance marketing agency runs paid media campaigns, tests creative and landing pages, and reports what the ad spend produced. For a B2B company the useful version goes further than lead generation and connects marketing activity to the CRM, so lead volume can be read against opportunities and revenue. The common channels are these five:

• Paid search on Google Ads and Microsoft Advertising, which captures buyers already looking for a solution
• LinkedIn advertising, which reaches target audiences by job title, seniority, company size and named account
• Paid social on Meta and Reddit, mostly for retargeting and cheaper reach into known accounts
• Programmatic advertising and connected TV, used by larger account based marketing programs
• Conversion rate optimization and lifecycle marketing, which decide whether paid traffic turns into pipeline

Good performance marketing strategies in B2B start from the sales process and work back to the channel. Influencer marketing and retail media sit inside many consumer performance marketing programs. They rarely belong in a B2B plan, and no performance marketing agency below is scored on influencer marketing or retail media.

How much does a B2B performance marketing agency cost in the US?

Published US figures start at $2,500 a month for a managed entry tier and run past $26,000 a month for a full-service engagement, before media. Most agencies quote on request, usually as a flat retainer or as 10% to 20% of ad spend. Whatever the model, read the fee against customer acquisition cost rather than against the media budget.

Only three of the twelve performance marketing agencies below publish a price on their own site. AdConversion lists paid media management from $8,600 a month for accounts spending $25,000 or more on paid advertising. Refine Labs lists it from $14,000 a month on a six-month minimum, and The Growth Syndicate bills hourly against a €5,000 monthly minimum with 30 days' notice.

Who this guide is for, and who should skip it

This list serves US-headquartered or US-selling B2B companies with roughly $2M to $150M in annual revenue, spending about $10,000 to $150,000 a month on paid media. It assumes a sales team, a buying committee on the other side, and B2B marketing leaders whose business objectives are written as pipeline and revenue targets. They want their marketing programs measured on revenue contribution rather than platform conversions. B2B SaaS, technology companies, industrial firms, and professional and IT services all fit.

Every performance marketing agency profiled here is headquartered in the United States or, in our own case, runs a New York office alongside a European one. HQ cities are listed under "where each agency is based" so buyers who want a partner in their time zone can filter quickly.

Skip this guide if you sell to consumers, run an ecommerce or DTC brand, or need mobile app user acquisition. Skip it if you spend more than $1M a month across Amazon, streaming TV and retail media, since the enterprise media agencies built for that are listed under "also considered" and are the better call. Skip it if your paid budget is under about $5,000 a month, where a freelancer or an in-house hire will serve you better than any marketing agency here. And skip it if you want a neutral directory rather than a ranked opinion: Clutch and G2 list far more performance marketing companies, with verified client reviews and no editorial position.

At a glance: 12 B2B performance marketing agencies in the US

Use this table as a quick sort by fit. The profiles further down carry the detail and the evidence.

Evidence and terms behind each ranking

Every cell in this table can be checked against the profile below it, and every grade follows the definitions near the end of this article.

Where each agency is based

All twelve have a US headquarters or a US office. Team sizes marked as third-party come from directories rather than the agency itself, so treat them as estimates.

What the evidence check turned up

We counted four things across all twelve performance marketing agencies, as published on September 20, 2026. The counts are redone at every review.

• 11 of 12 publish at least one named B2B client next to a specific figure.
• 8 of 12 publish a figure at pipeline, opportunity or revenue level rather than leads or clicks.
• 3 of 12 publish any price on their own site, and 2 of 12 publish full pricing before a sales call.
• 5 of 12 publish a minimum spend, a stage requirement, or a plain statement of who they do not serve.

All three agencies that publish a price sit in the top five. The two largest agencies on this list by headcount publish no price and no B2B result at pipeline level. Size and transparency ran in opposite directions in this set, which is worth remembering when a well-known name is the easiest one to get past procurement.

The picks by category

Ranking twelve performance marketing agencies against one buyer flattens real differences, so each marketing agency holds a category it owns.

• Best for Series A to C SaaS wanting published pricing: AdConversion
• Best for paid media wired into go-to-market strategy: The Growth Syndicate
• Best for paid search and social tied to CRM attribution: Obility
• Best for SaaS scaling paid against CAC at larger budgets: Directive
• Best for moving from lead capture to demand creation: Refine Labs
• Best for paid, outbound and LinkedIn content as one system: Understory
• Best for PPC and landing pages at SMB budgets: SevenAtoms
• Best for growth-stage SaaS and fintech startups: Jordan Digital Marketing
• Best for long-cycle B2B needing ABM alongside paid: Ironpaper
• Best for high-cadence PPC and CRO testing: KlientBoost
• Best for paid and organic search under one large roof: NP Digital
• Best for buyers who weigh review volume most: Disruptive Advertising

Every profile below follows the same shape: who should hire them and for what, what they do, the results they publish with client names attached, who they fit, where they stop, and how strong the underlying evidence is. Read the opening verdict and the "where it stops" section first. Disqualifying an agency quickly is more useful than reading twelve full profiles.

1. AdConversion: best for Series A to C SaaS that want published pricing and no spend fees

Founded: 2023 · HQ: Miami, FL · Team: not published · Website: adconversion.com

Hire AdConversion when you are a venture-backed B2B SaaS company spending $15,000 or more a month on ads and you want to know the fee before the first call. It is the youngest performance marketing agency on this list and the most transparent: the price list is public, fees are flat rather than a percentage of spend, and the site states who it will not take on. That combination, plus seven named SaaS clients with pipeline-level figures, is why it leads.

What they do. Paid media strategy and execution across Google Ads, LinkedIn and Meta for B2B SaaS, sold alongside separate performance creative, CRO and RevOps service lines that can each be bought on their own. A senior performance marketing manager runs each account against a strategy roadmap with weekly optimization. The agency grew out of a free B2B advertising education platform founded by Silvio Perez, and the course library doubles as a public record of how the team thinks about campaign management.

Verifiable results. ActiveCampaign reports its trial-to-customer rate moving from 10% to nearly 18%, with average revenue per account up 14%. Checkr reports reaching twice its pipeline goal in a single quarter. OpenSesame reports twice the sales accepted leads and a 50% quarter-on-quarter pipeline increase. DigitalOcean reports 57% quarter-on-quarter growth in engaged accounts, and Teero reports running 52% below its customer acquisition cost target for three months.

Best for. Series A to C B2B SaaS with a working product, a sales team, and at least $15,000 a month in ad spend. Particularly strong for marketing leaders who have been burned by percentage-of-spend fees and want an agency whose income does not rise when the budget does.

Where it stops.

• B2B SaaS only. Industrial, services and hardware companies are outside its stated scope.
• Founded in 2023, so there is no long track record and no evidence of how accounts perform over several years.
• Paid media, creative, CRO and RevOps. Positioning, ICP work and content marketing are not on offer.
• The site describes "no fixed contracts" on one page and quarterly plans with 90 days' notice on the pricing page. Ask which applies to you.

Basis of assessment. Public information, the agency's published client results, and its pricing page. We have not engaged AdConversion directly.

Evidence grade: Strong. Seven named clients with figures, all inside the last three years because the agency is that young, and one of them (ActiveCampaign) discloses a baseline. The caveat is that every figure is a client quote rather than a full case study, so the method behind each number is not shown.

Pricing. Published in full. Performance from $8,600 a month for accounts spending $25,000 or more on media; an AI-managed tier at $2,500 a month below that level, with a 90-day performance guarantee; creative from $1,760, CRO from $3,323 and RevOps from $9,000 a month. Quarterly plans, 10% off annual plans, and no ad spend fees.

2. The Growth Syndicate: best for B2B companies whose paid media stalls for strategy reasons

Founded: 2024 · HQ: Amsterdam, NL and New York, NY · Team: ~20, senior only · Website: thegrowthsyndicate.com

Hire The Growth Syndicate when paid media is underperforming and you suspect the cause sits upstream of the ad account: positioning that does not separate you, an ICP defined too widely, or an offer nobody asked for. We are a B2B marketing agency that runs performance marketing inside a go-to-market plan rather than as a standalone media service. This is our own list, so read this profile with that in mind and check the case studies yourself.

What they do. Our performance marketing service covers Google Ads, LinkedIn and Meta, with Microsoft, Reddit and Quora used as experiments. It is rarely sold alone.

Most engagements pair paid with positioning and ICP work, account based marketing, demand generation, content marketing, SEO and CRM setup, led by a senior marketer who works as an embedded head of growth. The order is deliberate. Performance marketing built on weak positioning buys expensive clicks, so we fix what the ads say and who they reach, then scale the ad spend.

Verifiable results. For Nobel, a recruitment firm for SaaS sales talent, January to September 2025 produced €1.5 million in inbound pipeline, €1 million in new revenue influenced by LinkedIn campaigns, and a 206% return on paid spend. For Madeinadd, an Italian digital manufacturing platform, seven months from March 2024 produced more than 300% revenue growth, a 358% increase in Google Ads conversions and a 65% fall in cost per click. For Frends, an integration platform, ABM and paid programs produced 24 direct opportunities and moved MQL-to-SQL conversion from 14% to between 25% and 30%. For Cutr, a wood manufacturing marketplace, LinkedIn ads at 3% to 7% click-through supported 40 or more qualified meetings a month.

Best for. B2B SaaS, tech companies, manufacturers and IT services firms between roughly $2M and $150M in revenue that want a strategic partnership rather than a media buyer, and predictable revenue growth rather than a one-quarter spike in lead volume. It suits internal marketing teams that are thin on senior experience and need someone to challenge the plan before spending against it.

Where it stops.

• Every named result above is a European client. We serve US companies from New York, but US buyers should ask us for US references.
• No consumer, DTC, ecommerce or mobile app work.
• We are a poor fit for a company that wants a large paid media account run at the lowest possible fee. A specialist further down this list will do that for less.
• Founded in 2024, so our track record is two years deep.

Basis of assessment. First-party. These are our own engagements and our own published case studies.

Evidence grade: Strong, first-party. Four named clients with pipeline, revenue and conversion figures, three of them dated inside the last 24 months. The limitation is the obvious one: we wrote the case studies and we publish this list, so the results are checkable but not arm's-length. Madeinadd's figures age out of the 24-month window at the next review.

Pricing. Hourly rates billed against a €5,000 monthly minimum, pay-as-you-go, with 30 days' notice to cancel. No rate card is published.

3. Obility: best for B2B tech tying paid search and paid social to CRM attribution

Founded: 2011 · HQ: Portland, OR · Team: ~35 (third-party estimate) · Website: obilityb2b.com

Hire Obility when your go-to-market plan is settled and you need a B2B-only execution partner for paid search and paid social, with reporting that reaches the opportunity stage. It has worked exclusively with B2B companies for fifteen years, and its client list reads like a directory of enterprise software. It is the deepest pure performance marketing specialist on this list.

What they do. Paid search, paid social, SEO, generative engine optimization and revenue operations for B2B companies, with Reddit advertising added as a named practice. The operating idea is "foundation before expansion": clean tracking, CRM integration and conversion definitions first, budget growth second. Reporting is built to connect marketing activity to pipeline, so channel decisions are made on cost per opportunity rather than cost per lead.

Verifiable results. Equinix: lead volume up 99% and cost per lead down 61%. Snowflake: MQL volume up 105% at a 31% lower cost per MQL from paid social. Marketo: a 223% year-on-year improvement in pipeline per dollar, with the Google Ads ratio up 127%. Blackline scaled budget more than three times with CPA down 50%, and Vultr grew free trials 68% and paying users 43%.

Best for. B2B tech companies from Series A to publicly traded, with a marketing operations function that can give an agency CRM access. A good fit for enterprise organizations that want a specialist rather than a holding-company media team.

Where it stops.

• An execution partner. It will run the plan well and will not write your positioning.
• No pricing on the site. Third-party directories list a $5,000 minimum project size.
• Most case studies carry no date, so recency is hard to judge from the outside.

Basis of assessment. Public information and the agency's published case studies. We have not engaged Obility directly.

Evidence grade: Strong. More than six named enterprise clients with specific figures, several at pipeline level. The missing dates are the weakness, and they are the first thing to ask about.

Pricing. Not published.

4. Directive: best for SaaS and tech scaling paid media against CAC and pipeline

Founded: 2014 · HQ: Orange County, CA, with offices in Austin and New York · Team: not published · Website: directiveconsulting.com

Hire Directive when you are a funded SaaS or technology company with a mid-market or enterprise budget and you want paid media, SEO, CRO and design from one performance team. Directive calls its method Customer Generation, which in practice means modeling spend against lifetime value and customer acquisition cost, then reporting on opportunities and revenue. It ranks first in Google for several "best performance marketing agencies" searches, which says something about its search marketing.

What they do. Performance marketing for B2B across paid search, paid social, SEO, CRO, performance creative and video, organized into three divisions: Performance, Commerce and Communications. Financial modeling sits at the front of each engagement, so targets are set as revenue outcomes rather than lead counts. The agency also runs a large B2B marketing community and publishes heavily, which gives buyers plenty to read before a call.

Verifiable results. WordPress VIP: 175% more closed-won deals. Swoogo: an LTV to CAC ratio of 4.08 and a 105% quarter-on-quarter return. Arctic Wolf: 109% quarter-on-quarter growth in revenue from digital. Case Status: a 135% quarter-on-quarter increase in demo conversions and a 20% lift in bookings. dbt Labs: nearly twice its growth goals on a first paid campaign.

Best for. Series A to IPO B2B SaaS and tech companies with contract values large enough to justify a mid-to-upper retainer, and marketing leaders who want one agency accountable for paid and organic together.

Where it stops.

• The newer Commerce division serves ecommerce, so the agency is no longer B2B-only.
• Fit boundaries are implied by the client list rather than stated.
• Nothing about price appears on the site, including on the startup package page.

Basis of assessment. Public information and the agency's published case studies. We have not engaged Directive directly.

Evidence grade: Strong. Five named clients with figures at deal, revenue and ratio level. Most are percentages without baselines, so ask for the starting numbers.

Pricing. Not published. Third-party reviews most often cite engagements between $10,000 and $49,000.

5. Refine Labs: best for mid-market SaaS moving from lead capture to demand creation

Founded: 2019 (some directories list 2018) · HQ: Boston, MA · Team: ~60 (third-party estimate) · Website: refinelabs.com

Hire Refine Labs when your paid program fills a CRM with gated-content leads that sales ignores, and you want to rebuild it around buyers who ask for a demo. The agency made its name arguing against MQL-led demand generation programs, and its performance marketing practice is the working version of that argument. It publishes its prices, which is rare at this level of the market.

What they do. Paid social and paid search management, creative production, and a fixed-fee revenue performance assessment for B2B SaaS. The method shifts budget from lead capture toward demand creation and brand authority on LinkedIn and other social channels, aimed at narrowly defined target audiences, then measures "high intent" pipeline: opportunities that began with a direct request to talk to sales. Megan Bowen has been CEO since January 2024 and majority owner since July 2025.

Verifiable results. Fourth: SQLs up 44% and pipeline up 43%. MyCOI: 66% of paid search pipeline classed as high intent, with pipeline velocity up 161%. Firstup: hand-raisers up 46% and high-intent pipeline up 59%, first half of 2024 against first half of 2023. Zappi: average deal size tripled. dotCMS: demo requests doubled.

Best for. B2B SaaS at Series B and beyond, with real marketing budgets and a leadership team willing to stop counting MQLs.

Where it stops.

• The site says Series B and beyond. Earlier-stage companies are below its range.
• Six-month minimums on paid media and full service.
• Entry pricing sits above much of the buyer this list serves.

Basis of assessment. Public information, the agency's customer stories, and its pricing page. We have not engaged Refine Labs directly.

Evidence grade: Strong. Five named clients with figures, one with a dated comparison period. The definition of high-intent pipeline is the agency's own, so ask how it maps to your CRM stages.

Pricing. Published. Paid media management from $14,000 a month and full service from $26,000 a month, both on six-month minimums; creative from $5,000 a month; a six-week revenue performance assessment from $35,000.

6. Understory: best for funded SaaS running paid, outbound and LinkedIn content as one system

Founded: not published · HQ: not published · Team: ~34 (third-party estimate) · Website: understoryagency.com

Hire Understory when you are a post product-market-fit SaaS or AI company and you want paid media, outbound and founder-led LinkedIn content run from one set of data by one team. It calls the model "allbound". The client list is strong, the published numbers are thin, and the agency is candid about needing two quarters to show its work.

What they do. Five service lines sold as one system: paid media across LinkedIn, Google, Meta, Reddit and X; outbound campaigns built by GTM engineers; LinkedIn content for executives; creative and landing pages; and RevOps. The pitch is that paid audiences, outbound lists and content topics should come from the same account data, so each channel warms the next.

Verifiable results. Hiver reports more than 30 demos booked in its first six weeks, at lower spend than a previous $50,000 LinkedIn effort. RemoFirst reports a 40% increase in campaign performance. Named clients also include Clay, Zapier, Expensify, HockeyStack and Nylas, without figures attached.

Best for. Venture-backed B2B SaaS and AI companies with a go-to-market motion already running, that want to consolidate three vendors into one.

Where it stops.

• Six-month minimum, four for earlier-stage companies.
• No campaign-level case studies. The figures above come from client testimonials.
• No headquarters, founding year or team size on the site.

Basis of assessment. Public information and client testimonials on the agency's site. We have not engaged Understory directly.

Evidence grade: Moderate. Two named clients with a figure each, both from testimonials and neither with a baseline. A client list this good usually has better proof behind it than what is published, and the grade judges what is published.

Pricing. Flat retainers by service, never a percentage of spend. No figures published.

7. SevenAtoms: best for SaaS and B2B services that want PPC and landing pages from one team

Founded: 2013 · HQ: Dublin, CA · Team: not published · Website: sevenatoms.com

Hire SevenAtoms when you are a smaller SaaS or B2B services company and you want Google Ads, LinkedIn and the landing pages behind them handled by one Bay Area team. It publishes more named B2B case studies than most agencies three times its size. The numbers are percentages without baselines, which holds the profile back from ranking higher.

What they do. PPC management across Google Ads, Meta and LinkedIn, plus landing page design, content marketing and SEO. There is a named SaaS practice built around trials, demos and gated content, and a separate ecommerce practice. Paid social media ads and search run from the same account team.

Verifiable results. Imperva: 1,012% growth in closed customers from paid campaigns. Align Technologies: lead generation up 106% and sales opportunities up 55%. Fabric: leads up 267% and sales opportunities up 109%. Landpoint grew SQLs 630%, and Pro-Vigil grew sales opportunities four times over with monthly revenue up 482%.

Best for. SMB and lower mid-market SaaS, managed IT, and B2B services firms that need lead generation from paid channels without an enterprise retainer.

Where it stops.

• Serves ecommerce as well as B2B, so it is a general performance marketing agency with a B2B lean.
• No stated boundaries on who it takes.
• Case studies are undated and lead with large percentages.

Basis of assessment. Public information and the agency's published case studies. We have not engaged SevenAtoms directly.

Evidence grade: Strong. More than ten named B2B clients with figures, several at opportunity and revenue level. Every one is a percentage with no starting number, so treat the size of each lift with care.

Pricing. Model published: a fixed fee in month one, then a monthly fee plus a percentage of ad spend, with fixed monthly pricing on request. No figures.

8. Jordan Digital Marketing: best for growth-stage SaaS and fintech startups

Founded: 2017 · HQ: San Francisco, CA · Team: ~48 (third-party estimate) · Website: jordandigitalmarketing.com

Hire Jordan Digital Marketing when you have raised a round, need paid search and paid social working within a quarter, and want a performance marketing team that has done it for other venture-backed startups. Founder Tyler Jordan built the agency after working both agency-side and in-house, and the pitch is business outcomes first, channels second.

What they do. Growth marketing for venture-backed startups: paid search, paid social, SEO and content, run as an extension of a small in-house team. Campaigns are structured around pipeline and revenue targets where the client's tracking allows it.

Verifiable results. Secureframe: pipeline up 12% on 12% lower spend. Nimble: SQL volume up four times. Sentry: Google Ads conversions up 94%. Trusted Health: CPAs improved 71% while lead volume scaled.

Best for. Seed to Series C SaaS, fintech and developer-focused tech companies that need channel expertise quickly and do not yet have a paid media hire.

Where it stops.

• The client list includes consumer brands such as TrueCar and ZeroWater, so B2B is the majority of the work rather than all of it.
• No stated minimums or disqualifiers.
• Pricing is described only as a custom proposal.

Basis of assessment. Public information and results published on the agency's site. We have not engaged Jordan Digital Marketing directly.

Evidence grade: Strong. Four named B2B clients with figures, one at pipeline level. Short headline numbers rather than full case studies, with no dates.

Pricing. Not published.

9. Ironpaper: best for long-cycle complex B2B that needs ABM alongside paid

Founded: 2002 · HQ: New York, NY and Charlotte, NC · Team: 65+ · Website: ironpaper.com

Hire Ironpaper when you sell through complex sales cycles that run past nine months, deals are won account by account, and paid media has to support sales conversations rather than produce form fills. It is a B2B-only agency with two decades behind it. Paid is one lever inside its ABM and demand generation work, which is why it ranks mid-table on a performance marketing list.

What they do. Account-based programs, content marketing, paid media, website work and sales enablement for B2B companies with complex offers, mostly on HubSpot. Reporting centers on sales-qualified leads and influenced opportunities.

Verifiable results. Goddard Technologies: more than $3.5 million in influenced opportunities in 2023. Shell Catalysts and Technologies: more than 26,000 contacts generated since late 2018.

Best for. Industrial, technology and professional services firms selling high-value contracts to a short list of accounts.

Where it stops.

• States plainly that it is a poor fit for buyers who want cheap, fast leads.
• No outbound or appointment setting.
• Paid media is not the core practice.

Basis of assessment. Public information and the agency's published case studies. We have not engaged Ironpaper directly.

Evidence grade: Moderate. One named client with an opportunity-level figure and one with a contact count. The Goddard figure is from 2023 and will age out of the 24-month window soon.

Pricing. Not published.

10. KlientBoost: best for teams that want a high-cadence PPC and CRO testing rhythm

Founded: 2015 · HQ: Costa Mesa, CA · Team: ~65 (third-party estimate) · Website: klientboost.com

Hire KlientBoost when landing pages are the weak point and you want ads and pages tested together on a weekly rhythm. It is one of the best-known performance marketing agencies in the US and says it publishes more case studies than any other marketing team. For a B2B marketing team the issue is sorting the B2B proof from the ecommerce proof.

What they do. PPC across multiple channels, including Google Ads, Meta, LinkedIn and Microsoft, with in-house landing page design, performance creative, CRO experiments, SEO and email. The discipline is test volume: a structured experiment calendar rather than occasional bid changes. The agency reports hitting 83% of client goals in the second quarter of 2026 and an average 63% ROI increase in a client's first three months, both agency-reported aggregates.

Verifiable results. Alert Logic, a B2B cybersecurity company: cost per marketing-qualified lead down 32%, cost per conversion down 39%, lead volume up 62%. Segment, BP Logix, Excedr and Lavender are listed as B2B case studies, though we could not retrieve their figures this cycle.

Best for. B2B and SaaS companies with $5,000 or more a month to spend, a clear offer, and a conversion problem on the page rather than in the positioning.

Where it stops.

• Industry-agnostic by design, with a large ecommerce book.
• Tuned for channel execution. It will optimize campaigns, and it will not question the go-to-market plan.
• No pricing on the site.

Basis of assessment. Public information and the agency's published case studies. We have not engaged KlientBoost directly.

Evidence grade: Moderate. One named B2B client with figures we could verify. The library is large, and a B2B buyer should ask for three B2B cases with pipeline numbers rather than accept the headline count.

Pricing. Not published. Third-party directories list a $1,000 minimum project size, and review sites put typical retainers well above that.

11. NP Digital: best for brands that want paid and organic search under one large roof

Founded: 2017 · HQ: San Diego, CA · Team: ~950 (third-party estimate) · Website: npdigital.com

Hire NP Digital when you want paid media and SEO planned together by a large agency with its own tooling, and you have the budget and patience for an enterprise engagement. Co-founded by Neil Patel and Mike Kamo, it sells digital marketing services to everyone from SMBs to Adobe. Performance marketing for B2B is a practice inside it rather than the point of it.

What they do. Paid media, SEO, content marketing, digital PR, CRO and email, supported by proprietary technology including Ubersuggest and AnswerThePublic. The thesis is that paid and organic search should share one plan, with paid amplifying content that already ranks.

Verifiable results. Intelex: conversion rate up 60% from paid media. Universal Technical Institute: conversions up 145% and organic sessions up 411%. Verint: non-brand organic clicks up 210%, work that won the B2B category at the Drum Search Awards in 2023.

Best for. Mid-market and enterprise companies that want digital marketing across multiple channels from one supplier, judged on measurable growth in search visibility and conversions.

Where it stops.

• Consumer and ecommerce work is the majority of what it shows.
• B2B figures stop at conversions and traffic. None reaches pipeline.
• No pricing and no stated boundaries.

Basis of assessment. Public information and results published on the agency's site. We have not engaged NP Digital directly.

Evidence grade: Moderate. Three named B2B clients with figures, all at conversion or traffic level with no baselines. A strong general track record does not lift a B2B evidence grade.

Pricing. Not published.

12. Disruptive Advertising: best for buyers who weigh review volume most

Founded: 2012 · HQ: Pleasant Grove, UT · Team: 160+ · Website: disruptiveadvertising.com

Hire Disruptive Advertising when you want a large, established US performance marketing agency focused on paid media and CRO, and a long public review record matters more to you than published B2B case studies. It reports more than $450 million in annual managed ad spend and more than 350 Clutch reviews averaging 4.8. What it does not publish is a named B2B client with a number attached.

What they do. Paid search, paid social and social media advertising across Google Ads, Meta and LinkedIn, with conversion rate optimization, creative strategy and lifecycle marketing in the same engagement. The agency says it takes a limited number of new clients each month and retains more than 90 clients past four years.

Verifiable results. The published case studies are consumer-side: Arch RoamRight grew leads 10% at a 4x return on ad spend, and Security National Life grew lead volume 120%. The homepage shows B2B logos including KPMG, Adobe and Instructure with no figures attached.

Best for. Companies spending $20,000 or more a month that want paid and CRO from one experienced team and are comfortable judging fit from references rather than case studies.

Where it stops.

• No named B2B result on the site.
• Reviews from smaller accounts describe feeling underserved below about $5,000 a month in spend.
• No go-to-market or demand generation strategy work.

Basis of assessment. Public information and the agency's published case studies. We have not engaged Disruptive Advertising directly.

Evidence grade: Limited. No B2B client name is attached to any published result. A review record that deep suggests the work is solid, and the grade judges the published B2B evidence rather than the work.

Pricing. Not published.

Also considered, and why they are not on this list

Five names came close or appeared on the previous edition. Naming them is more useful than pretending the pool was only ever twelve.

• Madison Logic (New York). Publishes some of the strongest B2B figures we found, including a 30x return on influenced pipeline for Endava. Excluded because it is an ABM media platform with a managed service rather than a performance marketing firm, and its own positioning says so.
• Tinuiti (New York). The largest independent performance marketing agency in the US, with proprietary technology for media mix measurement. Excluded because we found no named B2B client with a figure anywhere on its site, and its contact form starts at $1M in annual spend.
• Logical Position (Lake Oswego, OR). Publishes two B2B results, including a 971% conversion rate lift for Kenco. Excluded because more than 7,000 mostly small ecommerce clients make it a different kind of agency.
• JumpFly (Hoffman Estates, IL). Publishes a dated 2025 result for Harvard Business Services. Excluded because ecommerce paid search and Shopping are the core of its work.
• Brainlabs (US operations of a London group). Absorbed the former Metric Theory team. Excluded because it publishes no named B2B result, and the Metric Theory brand the previous edition profiled no longer operates.

What would move a performance marketing agency onto this list at the next review: a published case study naming a B2B client, with a specific pipeline or revenue figure, dated within 24 months.

How we evaluated and ranked these B2B performance marketing agencies in the US

This section summarizes the method applied to this list. The standing version, including the full scoring anchors, the self-listing protocol, and the change log, lives on our "how we rank agencies" page, linked in the introduction.

The buyer this list serves

Before scoring anyone, we fixed who this list is for: US-headquartered or US-selling B2B companies with roughly $2M to $150M in revenue, spending about $10,000 to $150,000 a month on paid media, selling to buying committees, and wanting that spend measured on pipeline and revenue. That definition is published here because it determines every ranking below it. A performance marketing agency that would rank first for enterprise retail media can rank eleventh here without being a worse marketing agency.

The criteria and what each is worth

Five criteria decide the order, weighted as follows.

Verified client results (35%). Scored on what each agency publishes about B2B work: whether clients are named, whether metrics are attached to those names, how deep in the funnel those metrics sit, and whether baselines are disclosed. Pipeline and revenue outcomes outrank qualified leads, which outrank traffic, which outrank impressions. A 450% lift with no starting figure scores below a 14% to 30% conversion move.

Depth of B2B specialization (25%). Scored against B2B performance marketing specifically. Agencies that work only with B2B companies, treat paid media as the core practice, and build their performance marketing strategies for buying committees score highest. An agency doing excellent work for consumer brands scores low here, which is a statement about fit rather than quality.

Relevance to the buyer (15%). Measured against the definition above. Stage, budget, and engagement model all count.

Honest limitations (15%). Whether an agency publicly states who it does not serve. Explicit disqualifiers score highest, inferable boundaries score lower, and claiming to serve everyone scores lowest.

Transparent pricing (10%). Whether a buyer can learn anything about what a marketing agency costs before a sales call.

What we deliberately did not score

Eight things were left out on purpose:

• Awards and paid recognitions
• Google, Meta or LinkedIn partner tiers
• Total headcount
• Managed ad spend
• Star ratings without a visible review process
• Social following
• Whether an agency links to, mentions, or competes with us
• Personal relationships

Several agencies here publish their own rankings of the top performance marketing agencies and place themselves first. That had no effect on their scores in either direction.

What we did and did not test

We have not engaged any competitor on this list. Every assessment of another agency is built from published case studies, service pages, pricing pages, directory profiles, and stated positioning. Where an agency publishes no named-client metric, we say so and grade accordingly rather than filling the gap with reputation. Our own profile draws on our published case studies.

The publisher disclosure

The Growth Syndicate publishes this list and ranks itself second. That is a conflict of interest and no amount of process removes it. What we can do is make the reasoning checkable: the weights are above, the evidence grade for every agency including ours is on every profile, and the criteria are ones we would defend to a buyer who had never heard of us. Verified results, specialization depth, buyer fit, honest limitations, and transparent pricing are things a smart buyer would care about in a world where we did not exist. They also happen to be things we built this company around, which is a worldview you are free to reject.

AdConversion outscored us on this rubric, mostly on specialization and pricing transparency, and the margin between first and second is small enough that one judgment call could reverse it. We left the order as the scores fell. If either agency publishes new evidence, the ranking changes at the next review.

Editorial independence

• No agency paid for placement, and we do not sell placement.
• No affiliate or referral arrangements exist with any agency listed.
• No reciprocal listing agreements exist with any agency listed.
• Outbound links to the agencies listed here carry no commercial arrangement and are marked nofollow.

Who wrote and reviewed this

This article was written by Clément Dumont and reviewed by Joliene van Grieken, both founding partners of The Growth Syndicate. We are not going to claim a separation between scoring and ownership that does not exist at a company this size. What we can offer instead is that the buyer definition and the scoring anchors were fixed and published before any agency was scored, our own profile was held to named first-party results only, and every figure behind every grade is public. Re-run the assessment against the same evidence. If you reach a different order, we would rather hear it than not.

Corrections and consideration

If you are listed here and believe a fact is wrong, write to us and we will review it immediately; factual errors are corrected on discovery rather than at the next cycle. If you are not listed and believe you should be, the bar is in the "also considered" section above. Substantive corrections are logged in the change history at the foot of this article.

Market context: what changed for US B2B performance marketing buyers in 2026

Paid media is the only budget line still growing

Gartner's 2026 CMO Spend Survey, fielded January to March 2026 across 401 marketing leaders, put marketing budgets at 7.8% of company revenue, up from 7.7% a year earlier. Paid media took 31.4% of that budget, up from 30.6%, and was the only major category to grow. The same survey found 15.3% of marketing budgets going to AI while only 30% of CMOs felt ready to scale it. More money is flowing into performance marketing at flat overall budgets, so marketing spend on everything else is being squeezed, and every paid dollar is expected to show business outcomes.

Buyers decide earlier, and mostly without you

6sense's 2025 Buyer Experience Report, published in November 2025, found that B2B buyers first contact a seller 61% of the way through the purchase, down from 69%. Buying groups averaged about ten people. Ninety-four percent had ranked their preferred vendors before that first contact, and 77% bought from the vendor they ranked first. For a performance marketing program this changes the job: most of the persuading happens before a form is filled, and brand authority built through paid reach matters more than capture at the bottom of the funnel.

Search clicks are scarcer while paid costs steadied

A SparkToro and Datos study reported by Search Engine Land found that 68% of Google searches in the first four months of 2026 ended without a click. BrightEdge measured AI Overviews on 82% of B2B technology queries in February 2026. Organic search is sending less traffic, which pushes more B2B marketing budgets toward paid.

The cost side is calmer than expected. WordStream and LocaliQ's 2026 benchmarks, covering 13,474 US search campaigns from April 2025 to March 2026, recorded an average $5.42 cost per click and $66.69 cost per lead, the first fall in cost per lead since before 2020.

LinkedIn now takes about a quarter of US B2B digital ad budgets

eMarketer forecasts US B2B digital ad spending at about $23 billion in 2026, with LinkedIn taking close to a quarter of it. For high growth technology companies selling to named accounts, LinkedIn is usually the most expensive and the most precise of the marketing channels available. An agency that treats it as a lead form machine will waste most of that budget, which is why several profiles above stress creative strategy and audience work over bidding.

How to choose the right performance marketing agency for your B2B company

Write down what is broken in your B2B marketing before booking any calls. The most expensive mistake in this market is hiring a channel specialist when the go-to-market plan is the problem, or a strategist when the account only needs a better operator. The right performance marketing agency is the one built for the gap you have.

Most of the top performance marketing agencies will take the meeting either way, so the diagnosis has to be yours. Performance marketing strategies differ more by sales motion than by channel.

• If you are Series A to C SaaS and want the fee in writing first, AdConversion.
• If paid underperforms and you suspect positioning, ICP or offer, The Growth Syndicate.
• If the plan is set and you need B2B-only paid search and social with CRM reporting, Obility.
• If you want paid, SEO and CRO from one team at a mid-market or enterprise budget, Directive.
• If sales ignores your MQLs, demand generation needs a rethink, and you are at Series B or later, Refine Labs.
• If you want paid, outbound and LinkedIn content from one vendor, Understory.
• If you are a smaller SaaS or services firm and need PPC plus landing pages, SevenAtoms.
• If you just raised and need paid channels working this quarter, Jordan Digital Marketing.
• If deals take a year and are won account by account, Ironpaper.
• If the landing page is the bottleneck, KlientBoost.
• If you want paid and organic search from one large supplier, NP Digital.
• If a long public review record is what your procurement team needs, Disruptive Advertising.

If none of these describes you, you may not need an agency yet. Below about $5,000 a month in ad spend, a good freelancer or a first in-house hire will usually do more for profitable growth, and for the company's growth trajectory, than a retainer.

FAQ

Who are the top performance marketing agencies in the USA for B2B companies?

On published B2B evidence, the best performance marketing agencies for B2B companies in the US are AdConversion, The Growth Syndicate, Obility, Directive and Refine Labs. All five name B2B clients next to pipeline or revenue figures, and three of them publish pricing. Most roundups of the best performance marketing agencies lean on consumer work, which is why the order here looks different. Larger names such as KlientBoost, NP Digital and Disruptive rank lower here because most of their published proof comes from consumer and ecommerce work.

What are the best B2B SaaS performance marketing agencies?

For B2B SaaS specifically, four performance marketing agencies work only or mainly with software companies: AdConversion, Directive, Refine Labs and Understory. AdConversion suits Series A to C teams, Refine Labs starts at Series B, and Directive covers Series A through IPO. Obility is the pick when the SaaS company is large enough to need enterprise paid search and paid social with opportunity-level reporting.

Which performance marketing agencies are best for scaling B2B lead generation?

If the goal is more qualified leads at a lower cost, Obility and SevenAtoms publish the most lead-volume evidence, including Equinix at 99% more leads for 61% less per lead. If the goal is pipeline rather than lead volume, look at AdConversion, Directive and The Growth Syndicate, whose published figures sit at opportunity and revenue level. Scaling lead volume without checking what sales accepts is how vanity metrics get into a board deck.

What is the difference between a performance marketing agency and a digital marketing agency?

A digital marketing agency is any marketing agency selling digital marketing services, from web design to social media management. A performance marketing agency is the subset that buys media and is judged on measurable outcomes. In B2B the distinction matters less than the reporting: ask any agency whether its dashboard ends at the form fill or at closed revenue.

How do B2B marketing agencies measure performance marketing success?

The credible ones accept revenue accountability: they report what marketing contributes to pipeline and closed revenue, and they treat platform conversions as performance data rather than business outcomes. Expect cost per qualified lead, MQL-to-SQL conversion, cost per opportunity, customer acquisition cost by channel, pipeline created, and marketing-attributed revenue contribution. A report that stops at clicks and impressions is a vanity metrics report. All of it depends on the ad platforms being connected to your CRM, so an agency that never asks for CRM access is telling you where its reporting stops.

Is KlientBoost a good performance marketing agency for B2B?

KlientBoost is a capable PPC and CRO agency with a large case study library and one B2B result we could verify, for Alert Logic. It ranks tenth here because it is industry-agnostic, shows a lot of ecommerce work, and publishes no pricing. B2B buyers should ask for three B2B cases with pipeline figures before shortlisting it.

Which US cities have the most B2B performance marketing agencies?

The twelve performance marketing agencies on this list cluster in California (Orange County, Costa Mesa, San Diego, San Francisco and the East Bay), New York, Boston, Portland, Miami and Utah. Location matters less than it used to, since most run distributed teams. Time zone overlap with your sales team still helps, and a New York or Bay Area office is useful if you want in-person planning sessions.

Should a company outside the US hire a US-based performance marketing agency?

If you are entering the US market, a US-based performance marketing agency that already buys American media will save you a quarter of learning. US auctions on Google Ads and LinkedIn are more expensive than most European ones, and US buyers respond to different proof. Several agencies above work across regions, and we serve US and European clients from New York and Amsterdam.

How long before a B2B performance marketing program shows results?

The performance marketing agencies' own published terms are the best guide. AdConversion's entry tier carries a 90-day performance guarantee, Refine Labs and Understory ask for six months, and KlientBoost reports average ROI gains inside the first three months. With B2B buyers taking six months or more to purchase, expect measurable growth in leads and meetings inside a quarter, and revenue growth you can attribute in two to three quarters.

Are placements on this list paid, and does The Growth Syndicate profit from them?

No performance marketing agency paid to appear, and we do not sell placement, run affiliate links, or trade listings. We profit only if a reader hires us, which is the conflict disclosed at the top of this page. We rank second on this list, behind an agency we have no relationship with.

How is this ranking scored, and how often is it updated?

Each performance marketing agency is scored from 0 to 10 on five published criteria: verified client results (35%), depth of B2B specialization (25%), relevance to the buyer (15%), honest limitations (15%) and transparent pricing (10%). Rank follows the weighted score. The list is reviewed quarterly, and the next review is scheduled for December 20, 2026.

How can an agency dispute a placement or ask to be considered?

Write to us. Factual errors are reviewed immediately and corrected on discovery. Performance marketing agencies that want to be considered should meet the bar in the "also considered" section: a published case study naming a B2B client, with a pipeline or revenue figure, dated within 24 months.

The data behind this ranking

Every figure in this article came from one of three places, and they are not equally strong.

Our own results come from our engagements and our internal reporting. They are checkable in the sense that clients are named and the case studies are published, but they are not independently audited, and we have an obvious interest in them.

Competitor results come from what each performance marketing agency published on its own website. We did not test them. Where a figure came from a client testimonial rather than a full case study, we said so, and where team sizes or price ranges came from third-party directories we labeled them as estimates.

Market data is attributed inline to its source with a date.

The evidence grades work as follows. Strong means at least two named clients with specific published figures. Moderate means one named client with a figure, or several figures whose baselines are not published. Limited means no client name is attached to any published result, which is a judgment about the evidence rather than the work. Strong, first-party applies only to us and carries the arm's-length limitation described in our profile.

Read percentages critically wherever they appear, including ours. A large percentage with no baseline is the weakest common form of marketing proof, and nearly every marketing agency in this market uses it.

What changed in this update

This revision rebuilt the article rather than refreshing it. Six performance marketing agencies were removed for poor fit against the buyer this list serves, eight were added, and the order now follows scored evidence rather than agency size. The Growth Syndicate moved from first to second.

Review schedule. Reviewed quarterly. Next scheduled review: December 20, 2026. Out-of-cycle triggers: acquisition or merger, ownership or senior leadership change, new published evidence that changes a score, or an agency ceasing to operate. The date on this article does not change unless the content changes, and a year change in the title means the ranking changed.
