Top 9 account-based marketing agencies in the UK in 2026

Posted June 8, 2026. Last updated September 16, 2026, with a re-scored roster. Written by Clément Dumont, co-founder, The Growth Syndicate. Reviewed by Joliene van Grieken, co-founder. Scored on ranking methodology v1.2. Next scheduled review: December 16, 2026. No agency paid to appear on this list, and none can.

Which are the best account based marketing agencies in the UK right now?

For a UK B2B company with deals above £50K and a budget of £5K to £40K a month, strategicabm is the strongest pure-play account based marketing agency on published evidence. The Growth Syndicate ranks second and fits better when ABM has to be built alongside the rest of the marketing function. Gripped wins on published pricing for B2B SaaS, and The Marketing Practice leads for enterprise brand-to-demand programs.

The Growth Syndicate publishes this list and appears on it, at second place. Our placement cannot be bought, and neither can anyone else's. The scoring weights, the evidence grade behind every rank, and the process for challenging a placement are set out in the full methodology, which sits after the profiles. We scored ourselves on the same anchors as everyone else, and this year the honest result put a competitor above us.

What does an account based marketing agency in the UK actually do?

An account based marketing agency builds and runs programs aimed at a defined list of high-value accounts rather than at a broad audience. The work covers account selection, research into the key decision makers at each target, personalized campaigns across paid media, direct mail, content marketing, and sales outreach, and the reporting that ties account engagement back to pipeline growth. The best ABM agencies also align marketing and sales teams around one operating model: shared KPIs, joint account planning, and the CRM integration that lets both teams see the same account view. Most ABM agencies sell the campaigns; fewer fix the alignment.

How much does an ABM agency in the UK cost?

Across the 15 agencies we assessed, only two publish figures. Gripped states a typical investment of £5K to £15K a month with media billed separately, and The Growth Syndicate publishes an hourly rate model with a monthly minimum of €5,000. The rest name a model, usually a retainer, and disclose nothing else, so the cost of ABM services is established on a sales call. Enterprise one-to-one programs at agencies such as Transmission or The Marketing Practice sit well above this range, and the buyer should expect a six-figure annual commitment.

Which ABM tier do you need: one-to-one, one-to-few, or one-to-many?

One-to-one ABM builds a bespoke plan for a handful of enterprise accounts and only pays back when deal values reach the high six figures. One-to-few clusters 5 to 30 key accounts with a shared problem and runs tailored campaigns to each cluster. One-to-many uses marketing automation and intent signals to run multi-channel campaigns across hundreds of target accounts. Most UK companies in our buyer range start at one-to-few, and the agencies below differ sharply in which tier they are built for.

Who this guide is for, and who should skip it

This list is written for one buyer: a UK-headquartered or UK-serving B2B company in technology, professional services, or complex manufacturing, with roughly £2M to £50M in annual revenue, typical deal values above £50K, and a marketing budget of £5K to £40K a month excluding media. That buyer needs an account based marketing strategy plus multi-channel campaigns and sales alignment, usually at the one-to-few tier with some one-to-many, and may need the surrounding marketing strategy built at the same time.

Skip this list if any of these describe you:

• You sell to consumers, or your deal values sit below £20K, where targeting high value accounts one by one costs more than it returns.
• You want a single deliverable such as a one-off account research pack rather than a program.
• Your budget sits below the floor in the pricing FAQ, in which case a freelance ABM strategist or a first in-house hire is the better answer.
• You want a neutral directory. Clutch and G2 list far more UK ABM agencies with client reviews, and they have no stake in the outcome. We do, and we say so below.

The 10 best ABM agencies in the UK at a glance

Evidence and terms for each ABM agency

What we found when we checked the evidence

We ran the same four checks across all 15 UK ABM agencies we assessed for this update, the 10 listed and the 5 in the "also considered" section. The counts reflect what was published on September 16, 2026, and are re-counted at every review.

• 8 of 15 have at least one named client with a specific metric in the public record, six of them on the agency's own site and two only in third-party buyer guides. Seven have none, including three with strong reputations.
• 2 of 15 publish a price signal with figures. Gripped and The Growth Syndicate. The other 13 name a model at most.
• 0 of 15 publish a full rate card before a sales conversation.
• 5 of 15 state explicitly who they will not serve. The other 10 leave the buyer to infer fit from the client roster.

The observation worth keeping is the overlap between the first and last count. Three of the five agencies that state explicit disqualifiers are the top three on this list, and all three also publish named results from their ABM programs. Confidence in the evidence and honesty about the boundaries appear to travel together, and the ranking below rewards both. It is also a useful screen for the buyer: an agency that will not say who it turns away is unlikely to tell you when marketing and sales are misaligned on your side.

Every profile below follows the same shape: firmographics, a verdict on who should hire them, what they do, verifiable results, best for, where it stops, basis of assessment, evidence grade, and pricing. Read the verdict and "where it stops" first. Together they let you disqualify an ABM agency in under a minute, which is the fastest way through a list of ten and the fastest route to the right ABM agency for your marketing and sales teams.

1. strategicabm: best pure-play ABM methodology for B2B technology companies

Founded: 1995 (as listed by the agency). HQ: Horsham, West Sussex, with a London office. Team: 11 to 50. Website: strategicabm.com.

Hire strategicabm if you sell B2B technology, your target accounts are enterprises, and you want an ABM agency that does nothing except account based marketing. It is the only agency on this list that publishes several named clients with pipeline figures attached, and one of those programs won an independent award in 2025. The trade is that you get ABM and only ABM, so the rest of your marketing has to be handled elsewhere.

What they do. strategicabm describes itself as 100% ABM and 100% B2B technology. Its Modern ABM Journey framework runs six steps from account selection through insight, content, activation, sales enablement, and measurement. Engagements are typically one-to-one or one-to-few, built around deep research into the decision makers at each account, personalized microsites, LinkedIn activation, and sales playbooks that align sales teams with the marketing efforts on each account. The agency also runs the "Let's Talk ABM" podcast, which functions as a public record of how its team thinks about ABM strategy.

Verifiable results. Four named clients carry specific figures in the agency's published case library. AVEVA's program at GSK generated £7M of active pipeline and 46 new decision-maker relationships, and Forrester named AVEVA its 2025 B2B Programme of the Year for that account based marketing work. BlueBotics reached more than £4M in pipeline and £750K in closed-won revenue from a standing start.

Acxiom built £1.5M of pipeline in 120 days, although that program was presented in 2019 and is now well past 24 months old. GoodShape and Kineo reported more than £1M in opportunities from a one-to-many program.

SAP, Cloudflare, Snow, and Getac appear as clients without published figures.

Best for. B2B technology companies with enterprise target accounts, deal values in the high six figures or above, and an existing marketing team that can own everything outside the ABM program.

Where it stops.

• No demand generation, SEO, or brand work. If the ABM program needs a functioning marketing engine around it, that engine has to come from somewhere else.
• The one-to-one and one-to-few model is expensive relative to one-to-many programs, and the agency does not publish a starting price.
• Case studies are technology-only, so professional services buyers have less published evidence to check.
• The Acxiom result is from 2019; the AVEVA and BlueBotics results are the ones to weigh.

Basis of assessment. Public information: the agency's website, published case studies, the Forrester award announcement, LinkedIn, and Companies House.

Evidence grade: Strong. Four named clients with specific figures, two of them dated within 24 months and one corroborated by Forrester.

Pricing. Retainer model. No figures published.

2. The Growth Syndicate: best for ABM wired into a full go-to-market function

Founded: 2024. HQ: Amsterdam, with a US presence. Team: 15 to 20. Website: thegrowthsyndicate.com.

Hire us if you need an ABM strategy and the marketing engine around it at the same time: positioning, paid media, content, sales enablement, and the CRM plumbing that makes account engagement visible. We serve the UK market from Amsterdam and do not have a UK office, which matters if you want an agency in the room every week. We rank ourselves second here because strategicabm publishes deeper ABM-specific evidence, and the methodology does not allow us to argue with that.

What they do. We run account based marketing as one of six services, alongside demand generation, content, SEO and GEO, paid media, and revenue operations. ABM programs typically start at the one-to-few tier: high value target accounts selected with the sales team, buying-committee mapping, LinkedIn and paid media aimed at named accounts, founder-led content marketing, and a weekly loop between marketing and sales on how each account moves. We build the reporting so pipeline growth can be traced to specific accounts rather than to campaign totals.

Verifiable results. Four published case studies carry ABM-relevant figures. Frends generated 24 direct ABM opportunities, moved MQL-to-SQL conversion from 14% to 30%, and reached €75K in monthly recurring revenue from the Swedish market. Rapid Circle reached more than 15,000 unique ICP profiles and 1,100+ engagements in a single quarter, with more than 10 enterprise deals influenced or driven by ABM.

Axual recorded €306K in marketing-generated pipeline and €270K marketing-assisted. Cradle logged more than 10,000 account engagements and 60+ qualified sales interactions.

Best for. B2B companies between £2M and £50M in revenue that need ABM and demand generation campaigns run as one system, with the marketing alignment built in rather than bolted on.

Where it stops.

• No B2C, DTC, or e-commerce work, and no engagements below €5,000 a month.
• No UK office. Delivery is remote, with in-person work by arrangement.
• The agency is two years old, so there is no decade-long track record to inspect, and the case-study set is smaller than the enterprise agencies on this list.

Basis of assessment. First-party. These are our own published case studies, and we wrote this profile.

Evidence grade: Strong, first-party. The figures are published and checkable, but they are not arm's-length. A reader should weight them accordingly.

Pricing. Transparent hourly rates with a €5,000 monthly minimum, pay as you go, 30 days' notice, no retainer lock-in. Published on our homepage.

3. Gripped: best for UK B2B SaaS with published pricing

Founded: 2017. HQ: London. Team: about 34. Website: gripped.io.

Hire Gripped if you run a B2B SaaS or technology company between £2M and £50M in ARR and you want an ABM program that plugs into HubSpot and paid media without a long procurement cycle. It is the only UK agency on this list that publishes a price band, and it names the client profile it serves in plain terms. The limit is depth: ABM is one service among several rather than the core of the practice.

What they do. Gripped runs demand generation, paid media, SEO and GEO, content, and HubSpot implementation for B2B SaaS, with account based marketing offered as a layer on top. ABM campaigns typically run one-to-many: key accounts loaded into HubSpot, LinkedIn and paid media targeting those accounts, and content sequenced to buying stage. The agency is a HubSpot partner and builds most of its reporting inside that stack. Founders Steve Eveleigh and Ben Crouch remain hands-on.

Verifiable results. Two named clients carry specific figures. Crownpeak generated £1.3M in new pipeline in a single quarter, and Eficode reported a 252% increase in opportunity value from search. The agency also publishes aggregate figures across its client base, such as a 1,567% increase in traffic, which we have not counted because they are not attached to a named client. Ideagen, Epicor, and Ravelin appear as clients without published metrics.

Best for. UK B2B SaaS companies that want ABM inside a broader growth program, run on HubSpot, with a known monthly cost before the first call.

Where it stops.

• ABM sits alongside five other services, so the depth of one-to-one work is thinner than at a pure-play ABM agency.
• The client profile is explicitly B2B SaaS and technology, and there is no published work in professional services or manufacturing.
• Three months' notice on retainers, which is longer than the pay-as-you-go models elsewhere on this list.

Basis of assessment. Public information: gripped.io including the pricing page, published case studies, and LinkedIn.

Evidence grade: Moderate. Two named clients with figures, but several of the headline numbers are aggregate and self-reported.

Pricing. Published: a typical investment of £5K to £15K a month, with most marketing leaders investing £8K to £12K, media billed separately.

4. The Marketing Practice: best for enterprise brand-to-demand ABM programs

Founded: 2002. HQ: London and Oxford, with offices in Munich, Denver, and Sydney. Team: 500+. Website: tmpb2b.com.

Hire The Marketing Practice if you are an enterprise technology or telecoms company running ABM programs across regions, and you need creative, channel marketing, and account based marketing under one roof. Its named results are among the largest in the UK market. The fit for a £5K-a-month buyer is weak, and the agency's own positioning makes that clear.

What they do. The Marketing Practice, often shortened to tmp, is a full-service B2B agency that has grown through several acquisitions since 2021. ABM programs sit within an integrated model that also covers brand, demand generation, partner and channel marketing, and sales enablement. Programs are typically one-to-few or one-to-many across enterprise accounts, with creative and content built centrally and activated across markets, and with sales enablement layered in so sales teams can act on account engagement. Clients include AWS, ServiceNow, and Palo Alto Networks.

Verifiable results. Two named clients carry specific figures. The O2 Business ABM program generated £42M in pipeline against a £28M target and won two new logos worth more than £5M in-year revenue, according to The Drum Awards case study for the campaign, which won at The Drum Awards for B2B 2022 and is now older than 24 months. Virgin Media O2 Business's Samsung channel program produced £8.4M in pipeline, published on the agency's own site. AWS, ServiceNow, Palo Alto Networks, Nutanix, and Splunk appear as clients without published figures.

Best for. Enterprise companies with multi-region target account lists, established marketing teams, and budgets that support integrated creative and media at scale.

Where it stops.

• The buyer in this guide is below the agency's typical engagement size, and there is no published minimum to confirm the floor.
• The strongest named result is more than two years old and lives on an awards site rather than the agency's own.
• Several acquisitions in four years mean the team you meet may not be the team that produced the case studies.

Basis of assessment. Public information: the agency's website, The Drum Awards, published case studies, and LinkedIn.

Evidence grade: Strong. Two named clients with specific pipeline figures, with the caveat that the larger one is awards-site-published and aging.

Pricing. Not public.

5. Pretzl (formerly Agent3): best for intent-data-driven ABM at scale

Founded: 2013 as Agent3; Pretzl launched February 2026. HQ: London. Team: about 300 across the combined group. Website: agent3.com, now part of Pretzl.

Hire Pretzl if you want ABM programs driven by intent data and account insight at enterprise scale, and you are comfortable working with a large, newly merged agency. Agent3 was one of the first agencies anywhere to specialize in account based marketing, and that heritage carried into Pretzl when Next 15 combined it with Publitek, This Machine, Velocity, and Twogether. The open question is how much of the Agent3 ABM depth survives inside a 300-person group.

What they do. Pretzl runs insight, content, digital, and creative for enterprise B2B technology companies, with ABM as a core discipline inherited from Agent3. The JourneyLab platform tracks account engagement and buying-committee movement across target accounts, and the data driven ABM programs it supports typically run one-to-few and one-to-many across hundreds of enterprise accounts. Clients named publicly include Microsoft, Salesforce, Zscaler, Adobe, and LinkedIn.

Verifiable results. One named client carries a specific figure. Agent3's case study for Splunk reports that the ABM program engaged 244 accounts and influenced more than $58M of pipeline in the second half of the year, a 116x return, and the work won B2B Marketing's award for best use of account based marketing. The figure is agency-reported and undated beyond the half-year framing, so we treat it as one checkable metric rather than a recent one. Other clients are named without figures.

Best for. Enterprise technology companies that want account insight and intent signals to drive one-to-many ABM across large lists of key accounts.

Where it stops.

• The Agent3 brand was retired in February 2026, so the case studies belong to a predecessor and the current delivery team is unproven under the new name.
• Enterprise-only in practice. A £2M-revenue company will not be a primary segment.
• No published pricing and no published minimums.

Basis of assessment. Public information: agent3.com, pretzl.com, Next 15 announcements, and LinkedIn.

Evidence grade: Moderate. One named client with a specific figure, agency-reported.

Pricing. Not public.

6. Digital Litmus: best for HubSpot-native ABM and pipeline measurement

Founded: not stated publicly. HQ: London. Team: not stated publicly. Website: digitallitmus.com.

Hire Digital Litmus if you run a mid-market B2B company on HubSpot and you want an ABM agency that talks about closed revenue rather than lead volume, and that will align marketing with what your sales teams are already doing. It is smaller than most agencies on this list and publishes less about itself, but the one result it publishes in full is a closed-revenue figure, which is rarer here than a pipeline figure. It is a HubSpot solutions partner and delivers in 90-day sprints.

What they do. Digital Litmus integrates what it calls systematic ABM with revenue operations and HubSpot implementation. Programs typically run one-to-few: target accounts agreed with sales, an ICP strategy and data foundations built first, then quarterly campaigns of tailored content, SEO-led supporting content, and personalized sales outreach aimed at those accounts. Reporting is built to show how accounts progress and contribute to pipeline rather than form fills. Clients named publicly include Spektrix and Supporting Education Group.

Verifiable results. One named client carries specific figures. For Spektrix, the agency reports £1.6M closed, 307 MQLs, and 48% of target accounts engaged from the ABM engine it designed and ran. The figures are agency-reported and undated. The Supporting Education Group case is a HubSpot implementation across nine businesses and carries no performance metric.

Best for. B2B SaaS and technology companies between £2M and £30M in revenue that run on HubSpot and want ABM measured on pipeline and closed revenue.

Where it stops.

• Firmographics are not published, so the buyer has to establish team size and founding date on a call.
• The published case-study set is small, and only one carries specific figures.
• No published pricing, although the agency offers a ballpark pricing guide on request.

Basis of assessment. Public information: the agency's website, published case studies, and its Clutch profile.

Evidence grade: Moderate. One named client with specific figures, including a closed-revenue figure.

Pricing. Not public. A ballpark pricing guide is available from the agency on request.

7. Ledger Bennett: best for ABM integrated with revenue operations

Founded: 1985. HQ: London. Team: about 95. Website: ledgerbennett.com.

Hire Ledger Bennett if your ABM program needs to sit on top of a rebuilt revenue operations layer, with marketing automation, data strategy, and CRM integration handled by the same team. Havas acquired the agency in February 2024, folding its own Havas Business unit into it, and B2B Marketing's 2025 league table ranked it the second-largest UK ABM specialist by gross income. What it does not do is publish its own client figures.

What they do. Ledger Bennett combines ABM with demand generation and RevOps under its "Forever Customer" model, which treats existing customers and new target accounts as one revenue system. Programs run across marketing automation platforms with a strong emphasis on data strategy, lead-to-account matching, and reporting that follows the account through the sales pipeline and the sales process. Clients named publicly include GE Digital, LinkedIn, Expleo, Aptean, and Indeed.

Verifiable results. One named result appears in third-party buyer guides: an 800% increase in engagement and $22M in pipeline attributed to an enterprise client. We could not trace it to the agency's own site or to a dated primary source, so we count it as a single attributed metric and no more. Havas reported 50% revenue growth at the agency between 2022 and 2024, which is a fact about the agency rather than a client result.

Best for. Mid-market to enterprise B2B companies whose ABM efforts have stalled because the data and automation underneath the marketing and sales efforts are broken.

Where it stops.

• The published evidence is thin relative to the agency's size and reputation, and none of it lives on the agency's own site.
• Enterprise-leaning. The agency's roster suggests the buyer in this guide would be at the smaller end of its client base.
• Havas ownership since 2024 adds network resources but also network processes, which some mid-market buyers find slow.

Basis of assessment. Public information: the agency's website, B2B Marketing's UK agency league table, third-party buyer guides, and LinkedIn.

Evidence grade: Moderate. One named client with a figure, published by a third party rather than the agency.

Pricing. Not public.

8. Transmission: best for multi-market ABM execution across global enterprises

Founded: 2013. HQ: London, with offices in Munich, Warsaw, Singapore, Delhi, Sydney, San Francisco, and New York. Team: 300+. Website: transmissionagency.com.

Hire Transmission if you are a global technology enterprise running account based marketing across several regions at once and you need programmatic ABM, media, and creative delivered by a single agency. It has been backed by Bain Capital Tech Opportunities since a strategic investment in October 2021 and still describes itself as independent. It is not a WPP or VML company, a point some third-party lists get wrong, including an earlier version of this one.

What they do. Transmission positions itself around account based experience, or ABX, which extends ABM across the whole customer lifecycle. Programs combine programmatic ABM platforms, paid media, creative, and content, typically at the one-to-many tier across large sets of enterprise accounts, with regional teams activating targeted campaigns in-market. Clients named publicly include HP, Microsoft, AWS, EY, Maersk, American Express, Cloudflare, and Software AG.

Verifiable results. One named result appears in third-party buyer guides: an O2 Business program reported at £260M in pipeline and £39M in revenue. The figure does not appear on the agency's own site with a date or baseline. Other clients are named without published metrics.

Best for. Global enterprises with target accounts across multiple regions, a central marketing team, and a budget that supports programmatic ABM at scale.

Where it stops.

• Built for large enterprises. The buyer in this guide is well below the agency's typical engagement and would not be a primary segment.
• The strongest published figure is third-party, undated, and lacks a baseline.
• No published pricing and no published minimum.

Basis of assessment. Public information: the agency's website, the Bain Capital investment announcement, third-party buyer guides, and LinkedIn.

Evidence grade: Moderate. One named client with a figure, published by a third party.

Pricing. Not public.

9. Inflexion Group: best for ABM strategy, training, and capability building

Founded: March 2021. HQ: United Kingdom. Team: not stated publicly. Website: inflexiongroup.com.

Hire Inflexion Group if you want to build ABM capability in-house rather than outsource execution, and you want to learn from the people who wrote the field's reference books. Co-founder Bev Burgess coined the term account based marketing at ITSMA in 2003 and has written the Kogan Page handbooks on it; the group publishes an ABM benchmarking study and runs the ABM Academy. It is a consultancy and training business, so it will not run your campaigns.

What they do. Inflexion Group offers ABM strategy consulting, program design, team training through the ABM Academy, and benchmarking against its annual study. Engagements typically start with an assessment of an existing ABM program or a plan for launching one, followed by training for the sales and marketing teams who will run it, including how to identify target accounts and how to measure the outcomes. The group says it has worked with more than 50 organizations, including Accenture, AWS, IBM, PwC, Salesforce, and Vodafone, and trained more than 10,000 marketers.

Verifiable results. No named client with a specific performance metric is published. The group publishes training clients and benchmark data rather than pipeline outcomes, which is consistent with what it sells. Ask for references from programs it has designed.

Best for. Companies with an in-house team ready to run ABM who need strategy, structure, and training to align marketing and sales, rather than an execution partner.

Where it stops.

• No execution. Campaigns, media, and creative have to be delivered by your team or a second agency.
• Enterprise-oriented clients and content. A £2M-revenue company will find the frameworks heavier than it needs.
• No published pricing.

Basis of assessment. Public information: the group's website, the ABM benchmarking study, and LinkedIn.

Evidence grade: Limited. No client name attached to a published result. This judges the published evidence, not the work.

Pricing. Not public.

10. MOI Global: best for creative-led enterprise ABM

Founded: 1987. HQ: London, with offices in Singapore, New York, Dubai, Sydney, and Munich. Team: 51 to 200. Website: moi-global.com.

Hire MOI Global if you are an enterprise technology company that wants ABM campaigns with strong creative at the center, delivered by a Demandbase-certified team. The agency acquired the ABM specialist Alias Partners in 2020 to form what it calls a global centre of excellence for account-based experience. Its client roster is among the strongest on this list, and it publishes almost nothing about what those clients achieved.

What they do. MOI Global runs creative, content, ABM, and events for enterprise B2B technology companies. ABM campaigns typically combine Demandbase account targeting with creative built for specific accounts or clusters, at the one-to-few and one-to-many tiers, with content marketing and events layered around the high value accounts that matter most. Clients named publicly include Oracle, ServiceNow, Akamai, NetSuite, Okta, Genesys, DXC, AWS, and Sage, and the agency has said it is putting a further 20 staff through Demandbase ABM certification.

Verifiable results. No named client with a specific performance metric is published. The roster is impressive, and the absence of figures is the reason the agency ranks tenth rather than fifth. Ask for case studies with numbers before the first proposal.

Best for. Enterprise technology companies that want creative-led ABM campaigns and already run Demandbase or a comparable platform.

Where it stops.

• Enterprise-only in practice. The buyer in this guide would be an edge case.
• No published metrics, which makes the strong roster hard to evaluate.
• No published pricing.

Basis of assessment. Public information: the agency's website, B2B Marketing's coverage of the Alias Partners acquisition, the Demandbase partner directory, and LinkedIn.

Evidence grade: Limited. No client name attached to a published result. This judges the published evidence, not the work.

Pricing. Not public.

Also considered

Five agencies were researched to the same depth and did not make the list. Each would move onto it at the next review with a published named-client case study carrying a specific figure, dated within 24 months.

• Momentum ITSMA: the successor to ITSMA, where the term account based marketing was coined, now part of Accenture Song after its September 2025 acquisition. Enterprise-only and no longer an independent boutique.
• Jabmo: an ABM platform for manufacturing and life sciences rather than a strategic agency, now an Expandi brand after entering administration in 2023. No named client with a metric.
• The Insight Collective (formerly Inbox Insight): owned-media and intent-led demand generation with an ABM service line. No named client with a metric.
• Cremarc: B2B technology ABM from Woking, credible and focused, but no published named-client figure.
• Radish: a creative ABM specialist for B2B challengers, project-priced. No published named-client figure.

Twogether was named the largest UK ABM specialist by gross income in 2025 and is now part of Pretzl, so it is covered under that profile. The ABM Agency is a pure-play with a London office but is US-led, and it is a better fit for our US list.

How we evaluated and ranked these account based marketing agencies in the UK

Every ABM agency on this list, including our own ABM agency, was scored on five parameters against fixed anchors, using public evidence only. The buyer definition at the top of this guide was written before any agency was scored and has not changed since. Rank follows the weighted score, and the weighted score put strategicabm first and The Growth Syndicate second. We publish the order and the evidence grades, not the point totals, because point totals invite arguments about decimals rather than about evidence.

The five criteria

Verified client results. What the agency publishes: named clients, specific figures, baselines, and dates. Pipeline and revenue outrank MQLs and traffic, which outrank impressions. This is the heaviest criterion because it is the one a buyer can check.

Depth of ABM specialization. Whether ABM is the whole practice, a stated focus with visible work, or one of many ABM services on a generalist menu. Scored against account based marketing specifically, so the same agency scores differently on our demand generation list.

Relevance to the buyer. Fit to the buyer defined above: stage, budget, engagement model, and problem. An enterprise-only agency can be excellent and still score low here.

Honest limitations. Whether the ABM agency states who it does not serve. Explicit disqualifiers score highest; "we serve everyone" scores lowest.

Transparent pricing. Whether a buyer can learn the model, a starting point, or a rate card before a sales call.

The weights

What we deliberately did not score

• Awards and paid recognitions, other than as corroboration of a published client result.
• Total headcount.
• Star ratings without a visible review process.
• Social following.
• Whether an agency links to, mentions, or competes with The Growth Syndicate.
• Personal relationships.

How we applied the criteria

We fixed the buyer definition, then researched all 15 candidates from their own websites, published case studies, partner directories, Companies House, LinkedIn, and dated press coverage. Each parameter was scored 0 to 10 against published anchors with a one-line justification citing the source. The weighted total set the rank. The verified-results score maps mechanically to the evidence grade: a score of 4 or below is Limited, 5 to 6 is Moderate, 7 or above is Strong.

What we did and did not test directly

We have not engaged any of the competitors on this list, and we did not run test briefs or mystery-shop them. Everything about them comes from what they publish and what third parties have published about them. Our own profile draws only on our published case studies, not on internal data.

Publisher disclosure

The Growth Syndicate publishes this list, appears on it at second place, and profits if a reader hires us. No process removes that conflict. What we can do is make the placement checkable: the criteria are ones we would defend to a buyer who had never heard of us, the weights are published, and the scoring anchors are on the methodology page.

The criteria reward what we were built to do, which is a worldview a reader is free to reject. This year they also rewarded a competitor more, and we published the result.

Editorial independence

• No paid placement. No agency has paid, or can pay, to appear or to move up.
• No affiliate arrangements with any agency listed.
• No reciprocal listings. Appearing on another agency's list has no effect on this one.
• Scoring is separated from business development. Nobody who sells our services scored a competitor.

Who scored and who reviewed

At a company of our size there is no separation between scoring and ownership, and a co-founder wrote this article. We do not claim founders were uninvolved. What we can state is that the buyer definition and anchors were fixed before scoring, our own profile was held to named first-party results only, every figure in every profile is public, and Joliene van Grieken reviewed the weights and every placement with the authority to change them. Anyone can re-run the assessment from the methodology page and the sources cited.

Corrections and consideration

If an agency on this list believes a profile is factually wrong, write to us and we will review it immediately. Factual errors are corrected on discovery rather than at the next cycle, and substantive corrections are logged in the change history below. An agency not on the list can ask to be considered at any time; the bar is in the "also considered" section above.

What changed for UK ABM buyers in 2026

The independent boutiques are consolidating

Two of the most recognized names in UK account based marketing stopped being independent within six months of each other. Accenture announced its acquisition of Momentum ITSMA in September 2025, folding roughly 90 specialists in London and Boston into Accenture Song. Next 15 then combined Agent3, Twogether, Publitek, This Machine, and Velocity into Pretzl, which went to market in February 2026. A buyer who shortlisted either name in 2025 is now dealing with a very different organization, and should ask which of the original ABM strategy team remains.

Independent awards are starting to validate ABM outcomes

Forrester named AVEVA its 2025 B2B Programme of the Year at B2B Summit EMEA in London in October 2025, for an account based marketing program that aligned marketing, sales, and customer success around the same high value accounts. The program was run with strategicabm, and it is the first case on this list where an independent body corroborated an agency-published ABM result. Buyers should ask every ABM agency whether any of its case studies carry that kind of external validation.

Published pricing remains rare

Only two of the 15 agencies we assessed publish a figure, and both sit at the smaller end of the market, where marketing efforts and marketing alignment are sold as one package. The enterprise agencies still treat pricing as a sales conversation. A buyer in the £5K to £40K range should expect to spend two or three calls establishing whether an enterprise-oriented ABM agency will take the engagement at all.

Vertical ABM agencies are a growing search category

Searches for fintech, biotech, medtech, pharma, and life science ABM agencies now register at similar volumes to the general UK query, according to Ahrefs data pulled for this update. None of the ten agencies above is a vertical pure-play, though strategicabm and MOI Global concentrate on technology and Jabmo, in the "also considered" section, concentrates on manufacturing and life sciences. A buyer in a regulated vertical should weight industry experience above rank on this list, because the sales cycles, buying committees, and compliance constraints differ enough to change the ABM strategy.

How to choose the right ABM agency for your situation

• If you need pure ABM depth and have an existing marketing team: strategicabm.
• If you need ABM and the marketing engine around it built together: The Growth Syndicate.
• If you run B2B SaaS on HubSpot and want to know the price first: Gripped.
• If you are an enterprise running brand-to-demand programs across regions: The Marketing Practice.
• If account insight and intent signals at scale are the priority: Pretzl.
• If you want HubSpot-native ABM measured on pipeline and closed revenue: Digital Litmus.
• If your ABM efforts are failing because the data layer is broken: Ledger Bennett.
• If you need ABM executed across several regions at once: Transmission.
• If you want to build ABM capability in-house: Inflexion Group.
• If you want creative-led enterprise campaigns on Demandbase: MOI Global.
• If none of these describes you: you may not need an ABM agency yet. Below roughly £4,000 a month, a freelance ABM strategist working with your sales team, or a first in-house marketing hire, will usually return more than an agency retainer. Choosing the right ABM agency starts with knowing whether you need one.

Frequently asked questions about UK ABM agencies

What is account based marketing?

Account based marketing (ABM) is a B2B marketing strategy that treats individual high value accounts as markets of one. Instead of generating leads from a broad target audience and qualifying them afterward, sales and marketing teams agree on a target account list up front, research the decision makers at each account, and run tailored campaigns to move those specific companies through the sales process. It suits companies with long sales cycles, complex buying committees, and deal values large enough to justify the cost per account. Done well, with real sales alignment behind it, it can shorten sales cycles because every decision maker on the buying committee hears the same story at the same time.

What are examples of account based marketing?

The published case studies in this guide are examples. Frends worked with The Growth Syndicate to engage more than 300 target accounts and generate 24 ABM opportunities. AVEVA worked with strategicabm on a one-to-one program at GSK that produced £7M of pipeline. Crownpeak worked with Gripped on a one-to-many program that generated £1.3M in pipeline in a quarter, and each program combined account selection, personalized messaging, and a shared marketing and sales process.

What are account based marketing services?

Account based marketing services typically include account selection, buying-committee research, ABM strategy, personalized messaging and creative, paid media and LinkedIn campaigns aimed at target accounts, direct mail, sales enablement, marketing automation and CRM integration, and account-level reporting. Most ABM agencies offer a subset, and an account based marketing agency worth hiring will say which parts it does not do. Pure-plays such as strategicabm cover the ABM stack in depth; full-service agencies such as The Growth Syndicate or The Marketing Practice bundle it with demand generation and brand.

How do you measure ABM success?

Measure success at the account level rather than the lead level, which is the first thing an account based marketing agency should set up. The engagement metrics that matter are the number of target accounts showing activity, the number of decision makers engaged per account, and account progression through defined stages. The business outcomes are sales pipeline generated from target accounts, win rate on those accounts, deal size, sales cycle length compared with non-ABM deals, and revenue growth attributable to the program. Any ABM agency you hire should be able to show these per account, not only in aggregate.

How long does it take for ABM programs to show results?

Expect 90 days to see account engagement and six to twelve months to see pipeline, depending on your sales cycles. The Acxiom program at strategicabm, presented in 2019, built £1.5M in pipeline in 120 days; the Frends program at The Growth Syndicate took several months to move conversion from 14% to 30%. An agency that promises pipeline in the first month is describing outbound, not account based marketing.

How does ABM differ from demand generation?

Broad demand generation creates and captures interest across a whole market and lets the sales team qualify what comes in. Account based marketing (ABM) starts with the accounts and works backward, which trades reach for precision, and it is the better fit when revenue growth depends on a few dozen key accounts rather than on volume. Most B2B companies in the £2M to £50M range run both: broad demand generation to fill the top of the funnel and ABM for the accounts that would change the year. Several agencies on this list, including The Growth Syndicate, Gripped, and Ledger Bennett, run the two as one system.

Should you hire a pure-play ABM agency or a full-service B2B agency?

Hire a pure-play if you have an established marketing team and want ABM depth added to it. Hire a full-service agency if the marketing function itself needs work, because an ABM program on top of weak positioning, no content marketing, and a sales team that marketing has never aligned with will not produce pipeline. An agency that can align sales and marketing around the same accounts is worth more than one that only runs campaigns. On this list, strategicabm and Inflexion Group are the pure-plays; the rest bundle ABM with demand generation, creative, or RevOps.

Do UK ABM agencies work with companies outside the UK?

Yes. Transmission, The Marketing Practice, Pretzl, and MOI Global run multi-market programs from London, and The Growth Syndicate serves the UK from Amsterdam. For a buyer whose target accounts are UK-based, the relevant question is whether the agency's team understands the UK market and its data protection rules, which apply to account-level personalization under UK GDPR.

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

No agency paid to appear, and no agency can. The Growth Syndicate publishes the list, appears on it at second place, and profits if a reader hires us. We disclose that conflict rather than claim it does not exist, and we scored ourselves on the same published anchors as everyone else, which this year placed a competitor above us.

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

Every agency is scored 0 to 10 on five criteria, with verified client results at 35%, depth of ABM specialization at 25%, relevance to the buyer at 15%, honest limitations at 15%, and transparent pricing at 10%. The weighted total sets the rank, and the results score sets the evidence grade. The list is reviewed quarterly, with the next review scheduled for December 16, 2026, and out of cycle when an agency is acquired, changes leadership, publishes new evidence, or closes.

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

Write to us. A listed agency that believes a profile is factually wrong gets an immediate review, and errors are corrected on discovery. An unlisted agency is considered at the next quarterly review if it publishes a named-client case study with a specific figure dated within 24 months. Substantive changes are logged in the change history at the foot of this page.

The data behind this ranking

The numbers on this page come from three classes of source, and they are not equally strong.

First-party figures are The Growth Syndicate's own published case studies: Frends, Rapid Circle, Axual, and Cradle. They are checkable at the links in our profile, but they were produced by us, and a reader should read them with the same skepticism applied to any agency's own numbers.

Competitor-published figures are what each agency states on its own site or in awards entries, and third-party buyer guides where the agency's own site is silent. We have not verified them beyond confirming that they are published and attributed. Where a figure lacks a baseline or a date, we say so in the profile.

Market data is limited in this update to the Ahrefs search-volume figures in the market context section and to dated corporate announcements: the Accenture acquisition, the Pretzl launch, the Bain Capital investment in Transmission, and the Forrester award. We dropped the unattributed ABM performance statistics that circulate in agency content, the ones about win rates and revenue growth, because we could not trace them to a dated primary source.

The evidence grades used throughout mean the following:

• Strong: at least two named clients with specific, checkable figures.
• Moderate: one named client with a figure, or several figures whose baselines are not published.
• Limited: no client name attached to any published result, which judges the evidence rather than the work.
• Strong, first-party: The Growth Syndicate only, meaning the figures are checkable but not arm's-length.

Read every percentage on this page critically, including ours. A 252% increase from an unpublished baseline may be a small number, and a £7M pipeline figure is only as good as the definition of pipeline behind it.

What changed in this update

This September 2026 update re-scored the entire roster on methodology v1.2 and changed the ranking. strategicabm moved to first place on the strength of its published pipeline figures and the Forrester corroboration, and The Growth Syndicate moved to second. Momentum ITSMA, Jabmo, and The Insight Collective left the list, and Digital Litmus, Ledger Bennett, Inflexion Group, and MOI Global joined it. Agent3 is now profiled as Pretzl.

We corrected the ownership of Transmission, which an earlier version wrongly attributed to WPP, removed an unsourced market-size statistic, removed all images, and added the evidence grades, weights, counts, and disclosures described above.

Review schedule

This list is reviewed every quarter. The next scheduled review is December 16, 2026. We also review out of cycle when a listed agency is acquired or merged, changes ownership or senior leadership, publishes new evidence that would change a score, or closes. The date at the top of this page changes only when the content changes, and a new year in the title means the ranking was re-scored, not that the date was refreshed.

About the publisher and authors

The Growth Syndicate is a B2B marketing agency founded in 2024, headquartered in Amsterdam with a US presence, serving technology and industrial companies across Europe, the UK, and North America with demand generation, account based marketing (ABM), content, and revenue operations. We publish this series of agency lists because our buyers ask us who else they should consider, and we would rather answer that question in public with a method than in private with a shrug.

Clément Dumont, co-founder, wrote this article and applied the criteria to every agency. Joliene van Grieken, co-founder, reviewed the weights and every placement on September 16, 2026, with the authority to change them. Neither claims independence from the outcome, which is why every figure on this page is public and every score can be re-run from the methodology page.
