Top 12 B2B marketing agencies in Europe matched to buyer type

Posted June 23, 2026 · Last updated October 8, 2026 · Written by Clément Dumont · Reviewed by Joliene van Grieken · Methodology v1.2 · Next scheduled review January 8, 2027 · No agency paid for placement on this list.

Which are the best B2B marketing agencies in Europe?

The Growth Syndicate leads this list of B2B marketing agencies in Europe for companies that need a full marketing function rather than one channel. Gripped is the pick for UK SaaS and tech teams on HubSpot, YOYABA for software companies scaling in DACH (Germany, Austria, and Switzerland), and Grizzle for multilingual organic growth. Twelve agencies, ranked on published evidence, and each profile names who should not hire them.

The Growth Syndicate publishes this list and ranks itself first. Placement cannot be bought, and no agency paid to appear. The scoring weights, the evidence grade behind every rank, and how to challenge a placement are set out after the profiles and in full in how we rank agencies.

Key takeaways from the October 2026 review:

• The Growth Syndicate (the publisher) ranks first for B2B companies that need a connected marketing function. Gripped and YOYABA are the closest challengers, for UK SaaS on HubSpot and for software sold into DACH.
• Six of the 12 agencies publish a price. Published starting points run from £3,500 to €25,000 a month before ad spend, and none publishes a full rate card.
• Eleven of 12 publish a named client result, but only four date one to the last 24 months. Ask every agency for the date, the baseline, and a reference you can call.
• Six of the 12 have offices in two or more European countries. If DACH, France, or the Nordics matter, confirm native-language staff before you shortlist.
• B2B email rules differ by country. Germany requires prior consent; France and the UK do not for most business addresses. Ask for the agency's Legitimate Interests Assessment before any outbound starts.

Three questions buyers ask before they compare agencies

How much do B2B marketing agencies in Europe cost?

Among the six agencies on this list that publish prices, ongoing engagements start between £3,500 and €25,000 a month, before ad spend. The other six quote only after a call, and none publishes a full rate card. Price rises with the number of channels and countries in scope, so define both before you ask for a proposal.

The published starting points, as checked on October 8, 2026:

• Gripped: from £3,500 a month (advisory), £7,500 (performance), and £15,000 (full demand generation). Gripped says most clients spend £8,000–£12,000.
• YOYABA: from €5,000 a month for creative and paid strategy up to €25,000 for its full revenue marketing service, plus a share of ad spend on paid tiers.
• The Growth Syndicate: hourly rates with a €7,000 monthly minimum.
• Grizzle: digital PR plans from $6,000 a month.
• Skale: a $5,000 minimum project on its Clutch profile.
• The Digital Bloom: $50–$99 an hour on its Clutch profile.

For a wider benchmark, Clutch's digital marketing pricing guide (updated September 2026) puts typical retainers at $5,000–$50,000 a month. It is global and not specific to B2B, so treat it as an outer range.

Do you need a separate agency for each European market?

No. One agency is enough if it has native-language staff for your priority markets. Six of the 12 agencies here have offices in two or more European countries, and the at-a-glance table below lists where each one sits. For every market on your plan, ask who writes the ads and content in that language and whether it is written in-language or translated.

Run one agency for strategy and measurement, and add an in-country specialist only where a market's volume justifies a second contract. Two agencies reporting on different definitions of a qualified lead leave you with numbers you cannot compare.

What should you check about GDPR before you sign?

Ask for the legal basis behind every outbound channel and for the agency's documented Legitimate Interests Assessment (LIA), the short written test the UK regulator describes for relying on legitimate interests. Then check the email rules in each target market, because ePrivacy law is national. An agency that cannot answer in writing is a compliance risk you would carry.

The rules for business email differ sharply between markets. Germany's Act Against Unfair Competition (UWG), section 7, requires prior consent for email advertising even between businesses. France's regulator, the CNIL, allows prospecting without consent when the message relates to the recipient's job and offers an easy opt-out. The UK's ICO exempts corporate subscribers from the consent rule, though not sole traders.

Across all three, GDPR Recital 47 confirms that direct marketing can be a legitimate interest.

Five questions to put to any agency before outbound or intent-data work starts:

1. Which lawful basis do you use for each channel, and can we see the LIA?
2. How do you handle national email rules in each of our markets, starting with Germany?
3. Where does the contact and intent data come from, and how are opt-outs recorded?
4. Who is controller and who is processor, and will you sign a data processing agreement?
5. How do you label AI-generated images, audio, or video under the EU AI Act?

Who this guide is for, and who should skip it

This guide is for companies that sell to other businesses, have several people involved in each purchase, and are choosing a partner for one or more European markets. It assumes an ongoing engagement and a budget of at least €5,000 a month. If you are still deciding whether you need an agency at all, start with what a B2B marketing agency does.

Skip it if any of these describes you:

• You sell to consumers, run ecommerce, or sell direct to consumers.
• You need a single task, such as one website build or one campaign.
• Your budget is below €5,000 a month. A senior freelancer or a first in-house hire will usually serve you better.
• You want a neutral directory rather than a ranked view. Clutch and Sortlist cover far more agencies and do not rank them on a published method.

At a glance: 12 B2B marketing agencies in Europe compared

Evidence and terms behind each ranking

"Latest dated result" is the most recent date an agency attaches to a named client figure, or the date of a client-signed review confirming one. "None" in the price column means the agency publishes no price figure of its own.

What the evidence check turned up

We ran five checks across all 12 agencies on October 8, 2026. The counts are re-run at every review.

• 11 of 12 publish at least one named client next to a specific figure. Expandi Group is the exception.
• 4 of 12 attach a date within the last 24 months to any of those figures: The Growth Syndicate, Gripped, YOYABA, and Luxid.
• 6 of 12 publish a price signal with figures, on their own site or their own directory profile.
• 0 of 12 publish a full rate card before a sales conversation.
• 3 of 12 state in their own words who they will not serve: The Growth Syndicate, Gripped, and Grizzle.

Named results are now common in this market; dated ones are rare. Three of the four agencies that date their results also publish prices, and the top two places on this list go to the two agencies that date results, publish prices, and say who they turn away. A percentage without a date or a starting number tells you little, so ask for both on the first call.

The picks by category

Every agency on the list wins one category. The numbered ranking says which evidence is strongest for the buyer this guide serves; the categories say which agency fits which situation.

• Best for a connected marketing function, not a single channel: The Growth Syndicate
• Best for UK SaaS and tech teams on HubSpot with published pricing: Gripped
• Best for B2B software companies scaling in DACH: YOYABA
• Best for organic search and AI visibility across European languages: Grizzle
• Best for enterprise demand generation and partner programs across countries: tmp (The Marketing Practice)
• Best for marketing automation in industrial and tech B2B: Luxid
• Best for SaaS SEO reported in sign-ups and revenue: Skale
• Best for ABM, PR, and content under one group: Pretzl
• Best for senior-led SEO and attribution on a smaller budget: The Digital Bloom
• Best for global brand and demand programs at enterprise scale: Transmission
• Best for creative-led ABM and events for enterprise tech: MOI Global
• Best for intent data and account-based advertising across European markets: Expandi Group

How to read the profiles. Each one follows the same shape: firmographics, a verdict on who should hire the agency, what it does, its verifiable results with dates, who it fits, where it stops, the basis of our assessment, its evidence grade, and its pricing. To rule an agency out quickly, read the verdict and "where it stops" first.

1. The Growth Syndicate: best for B2B companies that need a connected marketing function

Publisher's entry. The Growth Syndicate publishes this list, so every figure in this profile is our own.

Founded: 2024 · HQ: Amsterdam, Netherlands, with a US presence · Team: 15–20 senior operators · Website: thegrowthsyndicate.com

Hire The Growth Syndicate if the marketing function itself is the gap, and strategy, execution, and measurement need to be built and run together. It suits B2B technology, industrial, and professional services companies with long sales cycles and buying committees of several people.

What they do. An embedded fractional team (part-time senior specialists who work inside your company) covering strategy, paid media, ABM (account-based marketing), demand generation, content, web, and sales enablement. Paid media runs on LinkedIn, Google, and Meta. RevOps (revenue operations: the CRM, data, and reporting that connect marketing to sales) is part of every engagement. Delivery covers the Netherlands, Belgium, Germany, the UK, the Nordics, and North America.

Verifiable results. Each figure links to its published case study and carries the engagement dates shown there.

• Nobel Recruitment (January to September 2025): €1.5 million in inbound pipeline and a 206% return on paid spend. LinkedIn campaigns influenced more than €1 million in pipeline.
• Frends (November 2024 onward): MQL-to-SQL conversion, the share of marketing-qualified leads that sales accepts, rose from 14% to 25–30%. ABM and paid programs produced 24 opportunities, and open opportunities in Sweden total about €75,000 in monthly recurring revenue.
• Madeinadd (2024): revenue growth above 300% in seven months and a 358% increase in Google Ads conversions.
• Cutr (2024): cold calls per booked meeting cut from 9–12 to 4–5, a 2.8x gain in outbound sales efficiency.
• Rapid Circle (2024–2025): more than 10 enterprise deals influenced or driven by ABM.

Best for. PE- and VC-backed B2B scaleups with €5M–€300M in revenue whose growth has stalled, venture-backed companies with €1M–€5M that need strategy and execution together, and bootstrapped firms with €1M–€20M that have had a poor agency experience.

Where it stops.

• Not built for B2C, ecommerce, or direct-to-consumer brands.
• Monthly budgets below €7,000 do not fit.
• It produces qualified pipeline; it does not replace a sales team.
• Markets outside Europe and North America are referred elsewhere.
• Founded in 2024, so its track record is shorter than most agencies on this list.

Basis of assessment. First-party: our own engagements and the case studies linked above. Results from engagements we do not consider arm's length are left out.

Evidence grade. Strong, first-party. Five named clients with specific figures, all from engagements in 2024 or 2025 and checkable on the linked pages. They are not arm's length: we report them ourselves, and no third party has audited them.

Pricing. Hourly rates with a €7,000 monthly minimum, billed as you go, with 30 days' notice and no lock-in contract.

2. Gripped: best for UK SaaS and tech companies that want demand generation run on HubSpot

Founded: 2017 · HQ: London, UK · Team: about 25 (own site) · Website: gripped.io

Hire Gripped if you are a UK B2B SaaS, AI, or technology company from Series A upward and want paid media, organic search, and HubSpot operations run as one demand generation program. It publishes its prices and the companies it turns away, which shortens the first call.

What they do. Paid search and social, SEO and GEO (generative engine optimization, meaning visibility in AI-generated answers), content, HubSpot implementation, CRO (conversion rate optimization), marketing operations, sales enablement, and pipeline reporting. Gripped is a HubSpot partner.

Verifiable results. Case studies on gripped.io are undated; where a client-signed Clutch review confirms a figure, its date is given.

• Crownpeak: £1.3 million in pipeline in one quarter, a 247% increase in website conversions, and 4.8x return on ad spend (ROAS). Confirmed in a Clutch review by Crownpeak's VP of Marketing dated October 2, 2025.
• Cloudbooking: £2.4 million in pipeline, from an engagement running February 2024 to February 2025 per a Clutch review dated March 12, 2025.
• Blackdot: £2.1 million in pipeline in "the last financial year," with leads rising from 3 to more than 50 a month (undated).
• Terryberry: cost per SQL down 31% (Clutch review dated December 19, 2025).

Gripped's older headline figures, 1,567% traffic growth and a 4,300% rise in lead flow, come from its Vercator Software case study, where work began in 2018. Treat them as history rather than current proof.

Best for. UK B2B SaaS, AI, and tech companies with roughly £2M–£50M in annual recurring revenue (ARR) that run on HubSpot.

Where it stops.

• Says it does not typically work with pre-Series A or seed-stage companies.
• Does not take ecommerce, consumer brands, or generalist B2B, in its own words.
• One office in London, with limited capacity for programs in non-English markets.
• Not a brand or creative agency.

Basis of assessment. Public information: Gripped's case studies, pricing page, homepage FAQ, and client reviews on Clutch.

Evidence grade. Strong. Four named clients with pipeline or cost figures, three of them dated within the last 24 months by client-signed reviews.

Pricing. Published: advisory or execution from £3,500 a month plus project fees, performance from £7,500, and full demand generation from £15,000. Media spend and a one-time onboarding fee are extra.

3. YOYABA: best for B2B software companies scaling in DACH

Founded: 2019 · HQ: Hamburg, Germany · Team: 50–60 (self-reported) · Website: yoyaba.com

Hire YOYABA if you sell B2B software with more than €5M in ARR into Germany, Austria, or Switzerland and want paid and organic judged on pipeline. It works in German and English and only with software companies.

What they do. Paid social and search, creative strategy, organic growth through SEO and content, RevOps, and a full "revenue marketing as a service" package for larger accounts.

Verifiable results. From YOYABA's own success stories. Most carry no publication date; the period covered is given where the text states it.

• Proof: sign-ups and first job executions up 71.7% year on year, measured in Q1 2026.
• Loxo: pipeline from organic search up 126%, covering late 2024 into 2025.
• Infoniqa (now Suiteify): cost per SQL down 41% and a 1:4 ratio of spend to pipeline over an 11-month engagement (undated).
• Workist: 4:1 ROAS and 43% lead-to-SQL conversion, from work that began in 2023.
• HubSpot DACH: more than 124 deals from six webinars (undated).
• Haiilo: organic opportunities in DACH up 25%, covering 2022 to 2024.

Best for. B2B software companies above €5M ARR entering or scaling in DACH, especially those whose messaging has not been rebuilt for German-speaking buyers.

Where it stops.

• Software companies only.
• Built around DACH, with less published work in the Nordics or in Southern and Eastern Europe.
• Its paid tiers are designed for at least €10,000 a month in ad spend, and its full service for companies above €15M ARR.
• Paid and organic led; not a brand agency.

Basis of assessment. Public information: YOYABA's success stories and pricing page.

Evidence grade. Strong. Six named clients with figures on its own site, one measured in Q1 2026.

Pricing. Published starting prices: creative strategy from €5,000 a month and full paid media from €10,000, both plus a share of ad spend; organic growth €7,500; RevOps €6,900; and revenue marketing as a service €25,000. No minimum contract term.

4. Grizzle: best for B2B SaaS compounding organic search and AI visibility across languages

Founded: 2016 · HQ: London, UK · Team: not stated (under 50 on directories) · Website: grizzle.io

Hire Grizzle if you are a SaaS company past product-market fit and want content, SEO, AI search, and digital PR to compound over time, in more than one European language. It is an organic specialist and says so.

What they do. Technical SEO and content strategy, AI search and GEO, content production, digital PR, link building, original research, video and YouTube, and localization by native speakers. Engagements start with a 60-day commitment, then roll monthly.

Verifiable results. Grizzle's case studies are undated.

• Pipedrive: 39% global revenue growth in eight months, four times the organic traffic, and 33% more sign-ups.
• SmileBack: revenue up 47%.
• Tide: search traffic up 112% in 12 months and about 5,000 ebook sign-ups.
• Seraph Science, a professional services firm: three times the SQLs and 42 leads in 30 days.

Best for. Scaleup and mid-market SaaS companies building pipeline from content and search, particularly across several European languages.

Where it stops.

• Says it is "not the best option" for startups before product-market fit.
• Organic only: no paid media, brand, or creative.
• Not the right hire if the gap is the marketing function rather than a channel.

Basis of assessment. Public information: Grizzle's case studies, service pages, and its own published agency guide.

Evidence grade. Strong. Four named clients with figures, two at revenue level. None of the case studies carries a date, so ask when each result was achieved.

Pricing. Partly published: digital PR plans from $6,000 a month and sprints from $10,000. Full-service retainers are quoted on request.

5. tmp (The Marketing Practice): best for enterprise tech running multi-market demand generation and channel programs

Founded: 2002 · HQ: London, UK · Team: not stated on its site (reported as 500+ in 2022) · Website: tmpb2b.com

Hire tmp if you are an established technology, telecom, or professional services company that needs demand generation, ABM, and partner programs planned and measured across several countries. Expect enterprise scope and budgets to match.

What they do. ABM, demand generation, brand-to-demand programs (brand and pipeline work planned as one), channel and partner marketing, creative, media, research, and digital experience. Offices in London, Munich, Denver, and Sydney. The agency now trades as tmp.

Verifiable results. From tmp's own case studies, none of which carries a publication date.

• Thomson Reuters CoCounsel (2024 launch): $13 million in pipeline and $6 million closed-won from 380 opportunities.
• Virgin Media O2 Business with Samsung (channel program): £8.4 million in pipeline, 145% of target.
• T-Mobile for Business: partner-generated revenue tripled.
• Sage Pay: 3,559 qualified leads against a target of 1,000. An awards entry places this work in 2018.

Best for. Enterprise and upper mid-market B2B companies with complex buying cycles that need repeatable programs across several European countries and partner channels.

Where it stops.

• Enterprise scope and pricing; a third-party directory lists a £10,000 monthly minimum.
• Not suited to early-stage companies that need execution speed over planning.
• Continental European delivery runs through one office, in Munich.

Basis of assessment. Public information: tmp's case studies, trade press, and directory profiles.

Evidence grade. Strong. Four named clients with figures on its own site, two at pipeline or revenue level. Only the CoCounsel work can be placed in time, so ask for dates on the rest.

Pricing. Not disclosed. tmp advertises a fee-back guarantee ("No impact. No fee.") without publishing its terms.

6. Luxid: best for industrial and tech brands that need marketing automation tied to lead generation

Founded: 2022, from the merger of Finnish agencies ID BBN and Luxus · HQ: Finland (Helsinki and Turku), with offices in London, Austin, and Dayton · Team: 160+ · Website: luxidgroup.com

Hire Luxid if you are an industrial or technology company whose bottleneck is marketing automation: a platform such as Oracle Eloqua bought but not built properly, or leads that never reach sales. Its strength is connecting martech to lead generation across markets.

What they do. Marketing automation and martech, ABM operations, demand generation, content, digital advertising, analytics, and web. Luxid is part of the BBN network of B2B agencies, which handles delivery in markets where it has no office. It announced the acquisition of US agency TriComB2B in March 2025, after a minority investment from Voland Partners in August 2024.

Verifiable results. Luxid's case studies are undated; the periods below come from the case-study text.

• Kemppi: 937 sales leads in 2025, up 149%.
• Outokumpu: 9,736 marketing leads in 2023 against a 9,000 target, up 10.6%, with 32.3% more SQLs.
• Ampd: $8 million in pipeline from one eight-month campaign.
• Starburst: £700,000 in pipeline.

Best for. Industrial, manufacturing, and technology companies, often Nordic-headquartered with global ambitions, that need complex martech connected to pipeline.

Where it stops.

• Less brand and creative depth than the London enterprise agencies on this list.
• Delivery outside Finland, the UK, and the US runs through BBN partner agencies.
• The TriComB2B integration is recent, so team structure may still be settling.

Basis of assessment. Public information: Luxid's case studies, acquisition and investment announcements, and Oracle's published customer story on Outokumpu.

Evidence grade. Strong. Four named clients with figures, including two pipeline totals and one result dated to 2025.

Pricing. Set per engagement; no figures are public.

From the publisher

7. Skale: best for SaaS companies that want SEO reported in sign-ups and revenue

Founded: 2019 · HQ: London, UK, with a remote team · Team: not stated (10–49 on directories) · Website: skale.so

Hire Skale if you run a SaaS company with a product-led or hybrid motion and want organic search, including AI search visibility, reported against sign-ups and revenue rather than traffic. It works only with SaaS and tech companies.

What they do. SEO strategy and execution for SaaS, GEO and AI search visibility, content production, link building, and programmatic page builds, with reporting tied to sign-ups and monthly recurring revenue (MRR).

Verifiable results. Skale's stories are undated. The years below come from dates in the text or the case-study images, and most results are more than two years old.

• Maze: monthly organic sign-ups up 283% in under six months (around 2022).
• Holded: revenue from organic search up 279%, from a partnership that began in 2020.
• Perkbox: £110 cost per opportunity within ten months.
• Attest: organic product sign-ups up 8.5 times year on year (2022).
• AltoVita: $105,000 in new revenue in Q1 2024, per a client review on Clutch dated November 2024.

Best for. Growth-stage SaaS companies where organic search is a proven channel and the team wants it forecast and reported in revenue terms.

Where it stops.

• One channel: not a fit if paid media, brand, or RevOps are also gaps.
• SaaS and tech only.
• A remote team with no published offices in continental Europe.
• Few of its published results are recent, so ask for work from the last 12 months.

Basis of assessment. Public information: Skale's published stories and its Clutch profile.

Evidence grade. Strong. Five named clients with figures. Recency is the weak point: the newest dated result is from Q1 2024.

Pricing. No price on its own site. Its Clutch profile lists a $5,000 minimum project.

8. Pretzl: best for enterprise B2B buyers who want ABM, PR, and content from one group

Founded: announced October 2025 and launched February 2026, combining Next 15 agencies Agent3, Publitek, This Machine, Velocity Partners, and Twogether · HQ: London and New York · Team: about 350 (Next 15 investor presentation, January 2026) · Website: pretzl.com

Hire Pretzl if you are a technology, manufacturing, or financial services company that wants positioning, content, ABM, PR, and partner marketing from one group rather than several agencies. It is new as a brand, built from older agencies with long B2B records.

What they do. ABM, media, creative, PR and communities, SEO and GEO, martech, and partner marketing through its PartnerWorks division. At launch it described its JourneyLab AI and data platform as in beta. It lists eight offices, including Glasgow, Luton, and the Hamburg area in Europe.

Verifiable results. Every named figure we found predates the merger and comes from Agent3's undated case studies.

• Splunk: more than $58 million in influenced pipeline and a 116x return.
• Expereo: demand targets exceeded by 125%.
• McDonald's: franchisee applications doubled.

No Pretzl-branded case study with a client figure was published when we checked.

Best for. Enterprise-leaning B2B companies that want ABM, PR, content, and channel marketing coordinated under one contract.

Where it stops.

• A new entity whose combined case studies are not yet published.
• JourneyLab's current status is not stated on its site.
• Mostly UK and US offices, with one in Germany.

Basis of assessment. Public information: launch announcements, Next 15 investor materials, and the legacy agencies' published work.

Evidence grade. Strong. Three named clients with figures. All of them belong to Agent3 before the merger, so ask which current teams delivered them.

Pricing. Nothing public.

9. The Digital Bloom: best for growth-stage SaaS that needs senior-led SEO on a smaller budget

Founded: 2016 · HQ: Figueira da Foz, Portugal, with addresses in Florida and Toronto · Team: 2–9, plus a freelancer network · Website: thedigitalbloom.com

Hire The Digital Bloom if you are a growth-stage SaaS, fintech, or IT services company that wants senior people on SEO and demand generation, with revenue attribution, and cannot justify an enterprise retainer. Its core team is two senior leads backed by a freelancer network.

What they do. SEO, AEO and GEO (answer and generative engine optimization, meaning visibility in AI answers), content, demand and lead generation, ABM, CRO, paid media, analytics, and web development.

Verifiable results. From the agency's case studies, which are undated.

• SPD Technology: more than $1.3 million in marketing-attributed pipeline after one year.
• Master of Code: marketing-qualified leads from paid search rose from zero to 38 a month.
• The BA Girl Consulting: qualified leads up 550%.

The homepage also cites a 74.9% MRR increase for an unnamed client, and a second block on the same page gives 72%. The agency has a 5.0 rating from two reviews on Clutch.

Best for. Growth-stage SaaS, fintech, and IT services companies in English-language markets that want senior-led work without long minimum terms.

Where it stops.

• The smallest team on this list; not built for enterprise or multi-country programs.
• Strongest in English-language markets.
• Capacity is a real constraint at this size, so agree on who does the work before signing.

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

Evidence grade. Strong. Three named clients with figures, none dated. The core team is small, so confirm the people behind those results still deliver.

Pricing. Not on its site, which states only that there are no long minimum terms. Its Clutch profile lists $50–$99 an hour and a $1,000 minimum project.

10. Transmission: best for enterprise brands running global brand and demand programs

Founded: 2013, as Pulse; trading as Transmission since 2019 · HQ: London, UK, with eight offices in six countries · Team: 250+ (own site) · Website: transmissionagency.com

Hire Transmission if you are an enterprise or upper mid-market B2B brand running global or pan-European programs that combine brand, ABM, media, and events. It is independent and founder-owned, and it acquired London agency Earnest in January 2025.

What they do. Strategy, creative, ABM, paid media, PR and brand storytelling, events, sales enablement, and AI content and GEO work, mostly delivered in-house. European offices are in London and Wroclaw.

Verifiable results.

• Cashplus: beat a 10,000 sign-up target in under two months, and direct corporate sales rose 44% month on month (case study published July 2024).
• HP 3D Printing: $4.2 million in pipeline at a 52:1 return on marketing investment, from a B2B Marketing awards entry from around 2019–2020.
• Conduent: $1.2 million in pipeline from $20,000 in spend, from the same entry.

Transmission also holds trade awards, including Adweek's 2023 B2B Agency of the Year. Awards judge the agency, not client outcomes, so they do not count toward its grade.

Best for. Enterprise and upper mid-market brands in technology, financial services, professional services, and industrial sectors running global programs.

Where it stops.

• Enterprise pricing and structure; not built for small companies or startups.
• At this breadth, smaller accounts can get less senior attention.
• Its own site publishes figures for one client, so most of its proof is older third-party material.

Basis of assessment. Public information: Transmission's case studies and awards page, a B2B Marketing awards entry, and UK company filings.

Evidence grade. Strong. Three named clients with figures, but two come from an awards entry about six years old, and the newest result dates to 2024.

Pricing. Nothing public.

11. MOI Global: best for enterprise tech brands that need creative-led ABM and events

Founded: 1987 · HQ: London, UK, with offices in Munich, Dubai, New York, Singapore, Sydney, and Jakarta · Team: about 150 (own 2021 figure) · Website: moi-global.com

Hire MOI Global if you are an enterprise technology company that wants ABM, events, and experiential programs with strong creative, run by one agency across regions. It is privately owned and works almost entirely in technology.

What they do. Demand planning and performance media, ABM and ABX (account-based experience, which extends ABM to the whole buying group and customer journey), events and experiences, research, creative, brand strategy, influencer, and partner marketing.

Verifiable results. From MOI's own examples page, which is undated.

• Okta: 4.185 million in new influenced pipeline (the page gives no currency) and 22 opportunities.
• Oracle: pipeline up 50%.
• Cohesity: consideration up 21% and brand familiarity up 10%.

Best for. Enterprise technology brands that want creative, events, and ABM tied to pipeline from one global agency.

Where it stops.

• Almost entirely technology clients; limited relevance for industrial or professional services.
• Enterprise-oriented budgets.
• Not positioned for buyers who need only channel execution.

Basis of assessment. Public information: MOI's examples page, client list, and UK company filings.

Evidence grade. Strong. Three named clients with figures, none dated, and the Okta figure has no stated currency. Ask for dates and absolute numbers.

Pricing. Nothing public.

12. Expandi Group: best for tech companies that need intent data and account-based advertising across Europe

Founded: 2000, as NetPartnering in Paris · HQ: London, UK, with offices in Paris, Madrid, Milan, and Munich · Team: 250+ across the group, including Kompass · Website: expandigroup.com

Consider Expandi Group if you are a technology company, especially one selling through channel partners, that needs intent data and account-based advertising run across several European markets. Since 2024 its marketing services trade separately as Expandi Agency, so confirm which business you are buying from. It is unrelated to Expandi, the LinkedIn automation software company.

What they do. Demand generation, ABM, and channel marketing through Expandi Agency, plus the group's data and platforms: Cyance for intent data, Jabmo for ABM (assets bought in July 2023 after Jabmo entered administration), AccountInsight, and Session Media. It announced the acquisition of business directory Kompass in March 2026.

Verifiable results. None that meet our bar. No named client is published next to a specific figure: one client testimonial cites a 40% website improvement during a trial without defining the measure. The group shows client logos from large technology companies and says it generates "billions" in pipeline in total, which is self-reported. Its 2025 Frost & Sullivan award recognizes its platforms, not client outcomes.

Best for. Technology companies that need compliant intent data and account-based advertising across several EU markets, particularly channel-led programs.

Where it stops.

• Heavily focused on IT and technology clients.
• Not a brand or creative agency.
• Built for scaled programs rather than lean budgets.
• The agency and platform businesses now run separately, and the Kompass deal is recent.

Basis of assessment. Public information: Expandi's websites, acquisition announcements, and award records.

Evidence grade. Limited. No named client with a specific figure. This judges what Expandi publishes, not the quality of its work.

Pricing. Account-based advertising is sold per campaign, with no amounts published.

Also considered, and why they are not on this list

We assessed five more agencies for this review. Each came close, and the reason each is not on this list is stated plainly.

• Ledger Bennett: strong published proof, including $22 million in pipeline for Trend Micro, but it has been part of Havas Media Network since February 2024 and its own site no longer states a headquarters, size, or ownership.
• Dapper (Rotterdam): named results such as a 53% rise in leads for Online Payment Platform from 2023 to 2024, but its work centers on Dutch tech and SaaS brands. It appears on our Netherlands list.
• strategicabm (London): pipeline results such as £1.5 million for Acxiom in 120 days, but it is ABM-only and its published pricing starts at $20,000 a month, well above this list's budget floor.
• Bulldozer Collective (Paris): named results such as a 22% cut in search ad acquisition cost for PayFit, but it is centered on French scaleups and most deals start around €35,000.
• Avidly (Nordics): a strong HubSpot partner, but its published outcome figures are thin for a general marketing ranking.

An agency moves onto this list at the next review when it publishes a named-client case study with a specific figure, dated within the last 24 months, and fits the buyer defined below.

How we evaluated and ranked these B2B marketing agencies in Europe

The full method is published at how we rank agencies, methodology v1.2. This section explains how it was applied to this list.

The buyer this list serves

We fixed the buyer before scoring any agency: a company that sells to other businesses, has several people involved in each purchase, is choosing a partner for one or more European markets, and has at least €5,000 a month for an ongoing engagement. Every score for "relevance to the buyer" measures fit to that company and nothing else.

The criteria and what each is worth

Each agency is scored from 0 to 10 on five criteria, and the weighted total sets its rank. Verified client results carry the most weight because they are the hardest thing to fake. Pricing transparency carries the least because many good agencies quote per project for honest reasons.

Evidence grades map directly from the first criterion: Strong for two or more named clients with figures, Moderate for one, Limited for none. We publish the order and the grades, not point totals.

How we applied the criteria to a general B2B list

Every agency here works only in B2B, so specialization scores separate breadth from narrowness. Agencies focused on one sub-sector or one channel, such as SaaS-only SEO, score lower on specialization here than they do on lists built for their sector. No agency reaches the top of the specialization scale on this list, because none shows depth across all of B2B.

Pretzl and The Digital Bloom tied on weighted score and on verified results. The tie was resolved on relevance to the buyer, where Pretzl's multi-country reach fits this list's buyer better.

What we deliberately did not score

• Awards and paid recognitions.
• Total headcount.
• Star ratings without a visible review process.
• Social media following.
• Whether an agency links to, mentions, or competes with The Growth Syndicate.
• Personal relationships.

What we did and did not test

We did not hire, interview, or run trials with any agency on this list. Every score comes from what the agencies, their clients, regulators, or trade press have published, checked on October 8, 2026. Where a figure appears in two places with different numbers, the profile says so.

The publisher disclosure

We publish this list and rank ourselves first, and no process removes that conflict. What we can do is make the placement checkable: our buyer definition and weights were fixed before scoring, our profile cites only named, linked results, and every competitor figure comes from a public source you can find.

The criteria reward what we built The Growth Syndicate to do, and that is a worldview you are free to reject. Gripped and YOYABA are within reach. If either publishes more dated, pipeline-level results, or our own evidence ages past 24 months, the order changes at the next review.

Editorial independence

• No agency paid for placement, and placement is not for sale.
• No affiliate arrangements with any agency on this list.
• No reciprocal listing agreements.
• Scoring is kept separate from business development: no agency is scored up or down because it is a prospect, client, partner, or competitor.

Who scored and reviewed this list

Scores were applied by our content team against the published anchors. Clément Dumont, a co-founder, wrote the article. Joliene van Grieken, a co-founder, reviewed the buyer definition, the weights, every score, and the final order, and had authority to change any of them.

At a company of our size there is no separation between the people who score and the people who own the business, and we do not claim otherwise. What we offer instead is a method you can re-run: the buyer definition, the anchors, and every source behind a score are public.

Corrections and consideration

If a profile contains a factual error, write to us and we will review it immediately; factual errors are corrected on discovery rather than at the next review. Listed agencies can send newer evidence at any time, and every substantive correction is logged in the change history. Agencies not on the list are considered at the next review against the bar set out in "also considered."

Market context: what changed for B2B buyers in Europe in 2026

Buying groups grew, and buyers contact vendors later

Forrester's State of Business Buying 2026 (January 2026) found that a typical purchase involves 13 internal stakeholders and 9 external influencers. An agency has to reach a buying group rather than a single lead, which is why ABM and broad demand programs feature in most profiles above.

Buyers also arrive late. The 6sense 2025 Buyer Experience Report puts first contact with a vendor at 61% of the way through the buying journey, and the vendor contacted first wins about eight deals in ten. Ask any agency how it influences buyers before that first contact.

Discovery is moving into AI answers

In February 2024, Gartner predicted that traditional search engine volume would fall 25% by 2026 as people turn to AI chatbots and other virtual agents. Forrester's 2026 buying study adds that 94% of business buyers now use AI somewhere in the purchase process.

For agency selection, that means asking how an agency measures visibility in AI answers, not only rankings. Several agencies here, including Grizzle, Skale, Gripped, and The Digital Bloom, now sell GEO as a named service. Our explainer on SEO vs GEO covers what changes and what does not.

Compliance obligations became concrete

The transparency rules in Article 50 of the EU AI Act have applied since August 2, 2026. For marketing, the practical duty is disclosure: a business that publishes AI-generated or manipulated images, audio, or video resembling real people, places, or events must label them, and that duty falls on the business using the AI system, not only on the tool's maker. AI tool providers whose systems were on the market before August 2026 have until December 2, 2026 to add machine-readable marking, under amending Regulation (EU) 2026/1744.

Data protection enforcement keeps rising. DLA Piper's January 2026 survey counts €7.1 billion in GDPR fines since May 2018, about €1.2 billion of them in 2025. Outbound programs and intent data now need a documented legal basis before launch, not after.

Agency budgets are under more scrutiny

Forrester's 2026 survey of B2B marketers found the share expecting their agency budgets to rise fell 13 points from 2025, as more work moves in-house (Forrester). Agencies that publish dated, pipeline-level results are easier to defend in that budget conversation, which is one reason this list weights them most.

Europe also stays fragmented. The EU has 24 official languages, and IAB Europe's AdEx Benchmark 2025 (July 2026) tracks digital ad spend of €131.1 billion across 30 national markets. Every additional market adds language, regulation, and media differences to a program.

How to choose a B2B marketing agency in Europe for your situation

Write down three things before booking calls: the gap you need closed, the markets you need covered, and the monthly budget you can commit for at least six months. A costly mistake is hiring a channel specialist when the strategy is the problem, or a strategy-led agency when only one channel is underperforming.

Then match your situation to a three-agency shortlist:

• If the marketing function itself is the gap, start with The Growth Syndicate; at enterprise scale, also shortlist tmp and Pretzl.
• If you are UK SaaS or tech on HubSpot with £2M–£50M ARR, start with Gripped; also shortlist Grizzle for organic and Skale for SEO.
• If you sell software above €5M ARR into DACH, start with YOYABA; also shortlist The Growth Syndicate and Grizzle for German-language content.
• If organic search and AI answers are your main lever, start with Grizzle for several languages; also shortlist Skale and The Digital Bloom.
• If you run demand generation or partner programs across several countries at enterprise scale, start with tmp; also shortlist Transmission and Pretzl.
• If marketing automation is the bottleneck, especially in industrial B2B, start with Luxid; also shortlist The Growth Syndicate and tmp.
• If you need global brand and demand programs, start with Transmission; also shortlist tmp and MOI Global.
• If enterprise ABM needs creative and events, start with MOI Global; also shortlist Pretzl and Transmission.
• If you need intent data and account-based advertising across EU markets, start with Expandi Group; also shortlist Pretzl and MOI Global.
• If the budget is tight but you want senior attention, start with The Digital Bloom; also shortlist Skale and Gripped's advisory tier.
• If none of these describes you, you may not need an agency yet. Below €5,000 a month, or before product-market fit, a senior freelancer or a first in-house hire will usually do more for you than any agency on this page.

FAQ about B2B marketing agencies in Europe

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

No agency paid for placement, and we do not sell it. There are no affiliate arrangements and no reciprocal listings. We do profit indirectly: we publish the list, we appear on it, and readers who fit our buyer profile sometimes contact us. That commercial interest is why the method, weights, and every source are public.

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

Each agency is scored on five weighted criteria from public evidence: verified client results (35%), depth of B2B specialization (25%), relevance to this list's buyer (15%), honest limitations (15%), and transparent pricing (10%). The list is reviewed quarterly; the next review is January 8, 2027. Acquisitions, leadership changes, or new evidence trigger an earlier review.

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

Write to us with the evidence. Factual errors are corrected on discovery and logged in the change history. New evidence, such as a dated, named case study, is scored at the next review, and unlisted agencies are considered against the bar in the "also considered" section.

How do I verify an agency's case study before signing?

Ask for four things: the client's name, the date of the result, the starting number behind any percentage, and a reference you can call. A figure with all four is strong evidence; a percentage with none of them is marketing copy. Only four agencies on this list date a result to the last 24 months, so the date is usually the first gap you will find.

What can a company with less than €5,000 a month do?

Two agencies here publish entry points near that level: Gripped's advisory tier starts at £3,500 a month, and The Digital Bloom bills hourly with a $1,000 minimum project. Below that, a senior freelancer for one channel, or a first marketing hire supported by a quarterly strategy review, usually produces more than a small retainer.

What is the difference between a B2B marketing agency and a general digital agency?

A B2B agency plans for buying groups, long sales cycles, and pipeline reported in a CRM. A general digital agency is usually built for clicks, conversions, and ecommerce revenue. If your purchase involves several stakeholders and a sales team, hire for B2B experience first and channel skill second. Our B2B marketing benchmarks show what B2B performance typically looks like.

Does the EU AI Act change what an agency can do with AI?

Agencies can still use AI to research, draft, and produce. Since August 2, 2026, Article 50 requires that AI-generated or manipulated images, audio, or video resembling real people, places, or events be disclosed, and that duty sits with the business publishing them. Ask how the agency labels synthetic media and who signs off on it.

Should a European company hire a European or a US agency?

Hire a European agency if most of your pipeline sits in Europe. European buyers expect native-language content, national email rules differ, and GDPR applies to every contact you hold. A US agency can work for a European company selling mainly into North America; check its EU data processing terms before signing.

What is the difference between ABM and demand generation?

Account-based marketing (ABM) targets a defined list of accounts with coordinated, personalized programs. Demand generation builds interest across a whole market so that more buyers arrive already aware of you. Most B2B companies need both, weighted by deal size. Our guides to account-based marketing and demand generation cover each in depth.

How long before a B2B marketing agency shows results?

Paid programs usually show leading indicators within 60 to 90 days. Organic search and content typically take six to twelve months to show up in pipeline. Agree on the leading indicators for the first quarter before you sign, so you can tell early whether the work is on track.

Should we hire a specialist or a full-service agency?

Hire a specialist when one channel is underperforming and the rest of your marketing works. Hire a full-service partner when the gaps are spread across strategy, channels, and measurement, or when several agencies report on different definitions of success. The profiles above say which kind each agency is.

Should we build marketing in-house instead?

Build in-house when you know which channels work and need people to run them every day. Use an agency when you need senior judgment you cannot yet hire, or capacity for a defined period. Many companies combine both: a small internal team that owns the strategy, with an agency running execution in specific channels or markets.

Terms used in this guide

• ABM (account-based marketing): programs aimed at a defined list of target companies rather than a whole market.
• ABX (account-based experience): ABM extended to every member of the buying group and to existing customers.
• AEO and GEO (answer and generative engine optimization): work that makes a company visible in AI-generated answers, such as ChatGPT or Google's AI Overviews.
• ARR and MRR (annual and monthly recurring revenue): subscription revenue measured per year or per month.
• Brand-to-demand: brand building and pipeline generation planned and measured as one program.
• CRO (conversion rate optimization): testing and improving pages and forms so that more visitors take action.
• DACH: Germany, Austria, and Switzerland.
• Fractional team: part-time senior specialists who work inside your company for a set number of hours.
• LIA (Legitimate Interests Assessment): the documented test a company runs before relying on legitimate interests under GDPR.
• MQL and SQL (marketing- and sales-qualified lead): a lead that marketing judges ready for sales, and a lead that sales has accepted.
• ROAS (return on ad spend): revenue or pipeline generated per unit of ad spend.
• RevOps (revenue operations): the CRM, data, and reporting that connect marketing, sales, and customer success.
• ePrivacy rules: national laws on electronic marketing, such as Germany's UWG and the UK's PECR, which apply alongside GDPR.

The data behind this ranking

Every figure on this page falls into one of three classes, and they deserve different levels of trust.

• First-party data. Figures in The Growth Syndicate's profile come from our own engagements and published case studies. They are checkable but not arm's length.
• Competitor-published data. Figures in every other profile come from the agency's own website, client reviews on Clutch, or awards entries. We report them as published; where two pages disagree, the profile says so.
• Market data. Context figures come from named, dated research and regulators: Forrester, 6sense, Gartner, IAB Europe, DLA Piper, the European Commission, the UK ICO, and France's CNIL.

The evidence grades mean the same thing on every list we publish:

• Strong: at least two named clients with specific figures, published and checkable.
• Moderate: one named client with a figure, or figures without published baselines.
• Limited: no client name attached to any published result. This judges the evidence, not the work.
• Strong, first-party: applies only to us, and carries the arm's-length limitation stated in our profile.

Read every percentage critically, including ours. A large percentage with no starting number and no date is one of the weakest forms of marketing proof, and most agencies in this market use it somewhere, including on the pages cited here.

What changed in this update

This revision re-checked every agency against its own published evidence on October 8, 2026 and rebuilt the page to our current structure.

• The order changed. Gripped moved from 12th to 2nd after its pricing and four named pipeline results were verified; the previous version said it published neither. YOYABA moved from 2nd to 3rd, Pretzl from 11th to 8th, Transmission from 7th to 10th, and Expandi Group from 9th to 12th. The Growth Syndicate stayed first.
• Eight evidence grades rose as named, published results were found for tmp, Luxid, Skale, Gripped, The Digital Bloom, Transmission, MOI Global, and Pretzl. Expandi Group remains Limited.
• Facts corrected. Transmission is independent and founder-owned, not owned by Bain Capital, and the O2 figures previously attributed to it were removed. MOI Global's 2022 award claim was removed; it was shortlisted. YOYABA's top tier is €25,000, not €22,500. The Marketing Practice now trades as tmp. Unverifiable figures for Expandi Group and The Digital Bloom were removed.
• Our own profile changed. Our monthly minimum is €7,000 and our team is 15–20. Results we could not tie to a public case study or an arm's-length engagement were removed.
• Sources replaced. The previous pricing tiers cited a source we could not verify and were replaced with each agency's own published prices. The Gartner and Forrester figures were corrected to their current wording.
• New sections. Key takeaways, an evidence table with result dates, a GDPR checklist, a glossary, office locations, and three-agency shortlists by situation.

Review schedule. Reviewed quarterly; next scheduled review January 8, 2027. Out-of-cycle triggers: an acquisition or merger, a change of ownership or senior leadership, new evidence that changes a score, or an agency ceasing to operate. The date on this page changes only when the content does, and a year change in the title means the ranking changed.
