10 Best B2B Fintech Marketing Agencies at €2M–€10M ARR

A B2B fintech at €2M ARR usually has a dozen or so customers who would be hard to replace. A payments provider might count two mid-sized banks and a handful of marketplaces. A compliance platform might have a cluster of challenger lenders who signed after a regulator tightened the rules. Each of those relationships took months to win, involved a security review and a procurement process, and was helped along by someone who knew someone.

Growing from there to €10M means repeating that process many times over, with buyers who have no connection to the founders and every reason to be cautious. The sales cycle does not get shorter as the company grows. Compliance reviews do not get lighter. What changes is the volume of trust the company must earn, and the speed at which it must earn it, because investors priced the last round on a growth curve that relationships alone cannot draw.

After analysing growth programmes across more than 200 B2B SaaS and fintech accounts, fintech companies in this range tend to divide by how they treat marketing. Those that use it to make the company credible to strangers, through proof, precise messaging, and a steady presence where their buyers look, keep acquisition costs under control as they scale. Those that treat it as a lead machine bolted onto a sales team find that leads arrive faster than trust does, and that many of them never get past the first security questionnaire.

The agencies that serve this market range from fintech-only specialists with deep regulatory fluency to broader B2B partners with strong fintech practices. This guide compares ten of them, setting out what each does best for a fintech company between €2M and €10M ARR and where each falls short.

What Changes for Fintech Marketing Between €2M and €10M ARR

Four shifts define this stage for a B2B fintech, and each one affects the kind of agency that can help.

From warm introductions to cold evaluation. Early deals came with a recommendation attached. New buyers arrive with none, so the company itself must look credible on first inspection: in search results, in AI-generated answers, on its website, and in the evidence it can share. Marketing becomes the first reference check.

From founder knowledge to written proof. In the beginning, the founders could answer any question a risk officer asked. As the company grows, that knowledge has to exist in case studies, security pages, comparison guides, and technical articles that sales can send and buyers can find. Producing it accurately, and getting it approved, becomes real work.

From one market to several. Many fintechs in this range expand beyond their home country, or from one segment, such as challenger banks, into another, such as marketplaces or corporates. Each new market has its own regulations, vocabulary, and buying committee, and the messaging has to adapt.

From activity to accountability. Investors and boards now want to see pipeline by source, acquisition cost, and payback. Fintech sales cycles are long, so marketing must show progress months before revenue arrives, with tracking strong enough to connect the two.

An agency suited to this stage helps with at least one of these shifts in depth, and understands how its work affects the others.

Specialist or Generalist: Choosing the Kind of Agency

The first decision for a fintech in this range is not which agency, but which kind. The options sort into four groups, and most companies need more than one of them over time.

Fintech-only specialists such as CSTMR, Blue Train Marketing, and Mint Studios know the vocabulary, the regulators, and the buyers. Their work usually needs fewer corrections and passes compliance review faster. The trade-off is that many are strongest in one discipline, such as content or brand, and may rely on the client to connect that work to the rest of the funnel.

Channel specialists with fintech depth such as Perceptric and Omnius go deep on one route to market, usually search. For a fintech whose buyers research extensively before engaging, that depth can produce a durable source of pipeline. They rarely cover paid media, conversion, or CRM.

Systems and operations partners such as Evara and BrainDonors build the CRM, automation, and reporting that let a growing marketing function measure its work and stay compliant with data rules. They are essential infrastructure, though not usually the source of new demand on their own.

Integrated growth partners combine acquisition, conversion, nurturing, and reporting under one team. They suit companies that lack the in-house capacity to coordinate several specialists.

A useful test is to ask where the company is losing the most ground today: credibility, demand, conversion, or measurement. The answer points to the group to start with.

How We Chose These Agencies

• Fintech evidence: Named fintech or financial services clients, or a stated fintech focus backed by visible work.
• Fit with the stage: Client base, pricing, and team model suited to a company between €2M and €10M ARR.
• Handling of regulated content: A visible approach to accuracy, claims, and approval.
• Contribution to pipeline: Work that can be traced beyond awareness to opportunities or revenue.
• Range across the list: Together, the ten cover credibility, demand, conversion, and measurement, so readers can find the right type for their gap.

Each profile states plainly where the agency is strongest and where a fintech would need additional help.

The 10 Best B2B Fintech Marketing Agencies at €2M–€10M ARR

1. dimartec

Best for: Post-PMF B2B fintech and SaaS companies at €2M–€10M ARR that need credibility, demand, conversion, and reporting built as one system by one accountable team

dimartec builds Revenue Engines for B2B SaaS and fintech companies in this revenue band. Its five services, Performance Paid Media, CRO, GEO, Lead Gen & Nurturing, and RevOps & Automation, run as a single programme, which suits a fintech whose marketing team is too small to coordinate several specialists.

The programme is shaped around how fintech deals are actually won. Paid campaigns on Google and LinkedIn target the institution types and roles behind existing customers. GEO builds accurate visibility in ChatGPT, Perplexity, and other AI tools, where risk, finance, and operations buyers increasingly research unfamiliar vendors. CRO designs pages and forms that capture the information needed to judge regulatory fit before the first call. Lead Gen & Nurturing carries prospects through long, multi-person evaluations with content aimed at the questions compliance and procurement will ask. RevOps & Automation tracks every source through to closed revenue, producing the acquisition cost and payback figures investors expect.

In a published example, dimartec built iDenfy's growth engine across paid search, CRO, and AI-optimised content, producing €475k in qualified pipeline and €30k in closed revenue within three months on a 77-day sales cycle.

dimartec suits fintechs in this band when:

• Growth depends on founders' relationships and there is no repeatable channel for reaching new institutions
• Leads arrive but stall in security or compliance review
• Several suppliers handle different channels and nobody owns the outcome
• The board wants acquisition cost and payback by source, and the data does not exist

Key services

• Performance Paid Media: Google and LinkedIn targeting by institution type and role
• GEO: visibility in AI search for buyers researching unfamiliar vendors
• CRO: pages and forms that capture regulatory fit early
• Lead Gen & Nurturing: nurture for compliance-heavy, multi-person evaluations
• RevOps & Automation: attribution from first touch to closed revenue

Why dimartec stands out for fintech at this stage

• One team covering credibility, demand, conversion, and measurement
• Built around the long, regulated fintech sales cycle
• A published fintech result with named figures
• Designed for €2M–€10M ARR and handed to the client's team

Best fit: B2B fintechs in this band that need the whole growth system working together, not another single-channel supplier.

2. CSTMR

Best for: Fintechs selling into the US market that need brand credibility and paid acquisition developed together

CSTMR is a fintech-only marketing agency founded in 2014 and based in Austin, Texas. It works across payments, lending, banking, and financial software, and reports more than $150M in managed fintech ad spend. It holds SOC 2 Type 1 certification, which helps when client security teams review suppliers. Named clients include LendingTree and Credit Karma, with published results such as a 1.6x improvement in return on ad spend for Fincent and a sixfold pipeline increase for Airbase.

Its strength is pairing brand work with performance marketing. For a fintech in this band, that matters because paid campaigns aimed at sceptical financial buyers convert poorly when the brand behind them looks unproven. CSTMR builds the positioning and proof that make campaigns credible, then runs the campaigns.

Its client base leans towards US companies and consumer-facing fintech as well as B2B. European fintechs, or those selling only to institutions, should ask for directly comparable examples.

Key services

• Fintech brand strategy and positioning
• Performance marketing with claim substantiation
• Content for fintech buyers
• Account-based marketing
• SOC 2 Type 1 compliant data handling

Why CSTMR stands out for fintech at this stage

• More than a decade working only in fintech
• Brand and acquisition handled by one team
• Security certification that eases supplier review
• Published results with named clients

Best fit: US-facing fintechs needing credibility and acquisition together. Less suited to European fintechs selling only to institutions.

3. Evara (formerly Inbound FinTech)

Best for: Fintechs scaling their marketing and sales operations on HubSpot while staying within data and consent rules

Evara, which traded as Inbound FinTech until recently, is a London HubSpot partner founded in 2017 that works with financial services and fintech companies. It holds ISO 9001 and ISO 27001 certification and covers HubSpot implementation, revenue operations, data governance, consent and compliance management, SEO, and websites. Published clients include ConnexPay and Apply Financial.

Between €2M and €10M ARR, a fintech's CRM usually goes from a contact list to the system that runs marketing, sales, and reporting. In financial services, that system also has to record consent correctly and survive audits. Evara builds HubSpot with those requirements in place from the start, so the company does not have to rebuild it later under pressure.

Its focus is the system and inbound activity. Fintechs whose main gap is paid acquisition or outbound will need other partners.

Key services

• HubSpot implementation and optimisation
• Revenue operations and data governance
• Consent and compliance management
• SEO and inbound content
• Website design and development

Why Evara stands out for fintech at this stage

• Financial services and fintech focus
• ISO 27001 certification for security-conscious clients
• CRM built with regulatory requirements included
• Systems work combined with inbound marketing

Best fit: Fintechs committing to HubSpot. Less suited to companies on Salesforce or needing mainly paid acquisition.

4. Blue Train Marketing

Best for: Payments companies that need to be recognised and trusted within the payments community as they scale

Blue Train Marketing is a London agency founded in 2014 that has worked only in fintech and payments. Its CEO, Jeff Banks, was formerly international marketing director at First Data, now part of Fiserv. It is the marketing partner for industry bodies including the Payments Association, Open Banking Excellence, and Vendorcom, and its clients include Nuvei and Decta.

Payments is a connected industry where reputation travels through events, associations, and a relatively small group of decision-makers. A payments company growing from €2M to €10M ARR has to become known in that community, not only to rank in search. Blue Train's position inside the industry, together with its in-house content, SEO, and paid search skills, makes it well placed to help.

Its depth is in payments. Lenders, wealth platforms, and regtech companies will find less specialist knowledge.

Key services

• Payments messaging and branding
• Content for web, social, and events
• SEO and paid search
• Social media marketing
• Sales enablement material

Why Blue Train Marketing stands out for fintech at this stage

• More than ten years working only in fintech and payments
• Partnerships with leading payments industry bodies
• Senior payments marketing leadership
• Small team with in-house skills

Best fit: Payments and payment infrastructure companies. Less suited to other fintech segments.

5. Curious Cat Digital

Best for: UK fintechs wanting a small, senior team that combines strategy with account-based and performance marketing

Curious Cat Digital is a London agency founded in 2012 that works with fintech and financial services companies, both B2B and B2C. It describes itself as strategy-first and offers account-based marketing, performance marketing across Google, LinkedIn, and Meta, content, SEO, and analytics. One published engagement involved building an inbound strategy to increase leads for Cambridge Global Payments.

The agency is small, with around nine people according to company data, and clients note direct access to experienced marketers. For a fintech at the lower end of this band, that model can mean senior attention at a manageable cost, and a team that understands how financial buyers behave.

Its size limits the scale it can support. Fintechs running large multi-market programmes may outgrow it.

Key services

• Fintech marketing strategy
• Account-based marketing
• Performance marketing
• Content and SEO
• Web analytics

Why Curious Cat Digital stands out for fintech at this stage

• More than a decade in fintech and financial services
• Direct access to senior marketers
• Account-based capability suited to institutional buyers
• Strategy before execution

Best fit: UK fintechs in the lower half of the band. Less suited to large international programmes.

6. Mint Studios

Best for: Fintechs that want to turn their specialist knowledge into content that brings in qualified buyers

Mint Studios is a content marketing agency that works only with fintech and financial services companies. Its clients include Modulr, Zai, Jeeves, Persona, GBG, and ClearBank. Founder Araminta Robertson built the agency around proving that fintech content produces revenue.

Its method focuses on bottom-of-funnel topics, the questions buyers ask when they are close to choosing a provider, and builds each piece from interviews with the client's own experts. Results are tracked to pipeline, and the agency now pairs SEO with optimisation for AI search.

This suits a fintech in this band whose expertise sits in the heads of busy founders and product leaders. A short interview becomes an accurate article that sales can send and buyers can find. Mint Studios handles content only, so paid media and systems need other partners.

Key services

• Bottom-of-funnel content strategy
• Expert interview-led writing
• SEO and AI search optimisation
• Editing and publishing
• Content attribution

Why Mint Studios stands out for fintech at this stage

• Exclusively fintech and financial services
• Content built from the client's own expertise
• Measured against pipeline
• Strong list of fintech clients

Best fit: Fintechs with expertise worth capturing and content as a priority channel.

7. Perceptric

Best for: Fintechs that want organic and AI search to become a steady source of sales-qualified leads

Perceptric is an SEO and content agency focused on fintech and financial services. It combines SEO, optimisation for large language models, and compliance-aware content, and frames its work around the long evaluation periods typical of fintech buying. Its published case study reports doubling DeepIDV's user growth within three months, and it reports a 4.9 out of 5 client rating.

Fintech buyers research for months before contacting a vendor, which makes search, and increasingly AI-generated answers, an important place to be found. Perceptric's offer covers audit, a content strategy, and execution, including writing and design, under one programme.

Much of the comparative material about Perceptric is published on its own site, so independent references are worth requesting. Like other search specialists, it does not run paid media or CRM.

Key services

• Fintech SEO audits and strategy
• LLM and AI search optimisation
• Compliance-aware content writing
• Content design and visuals
• Organic performance reporting

Why Perceptric stands out for fintech at this stage

• Focus on fintech and financial services search
• AI search optimisation alongside SEO
• Content written with compliance in mind
• Published fintech case study

Best fit: Fintechs prepared to build search as a long-term channel. Companies needing pipeline within weeks should combine it with paid acquisition.

8. Omnius

Best for: European B2B fintechs expanding search across several markets and languages

Omnius is a European SEO and generative engine optimisation agency that works only with SaaS, fintech, and AI companies. Its published fintech results include a 60% increase in signups for ANNA Money, a UK business account provider, and a 227.9% increase in signups in six months for Myos, a working capital lender. It holds a 4.8 rating on Clutch.

The agency combines technical SEO, programmatic page creation, content, digital PR, and work aimed at being cited in AI answers. Its experience with localisation suits fintechs entering new European markets, where each country brings its own search terms and regulations.

Search takes time to build. A fintech that needs opportunities this quarter should run it alongside a faster channel.

Key services

• Technical and programmatic SEO
• SEO localisation
• Content and digital PR
• Generative engine optimisation
• Organic performance reporting

Why Omnius stands out for fintech at this stage

• Exclusive focus on SaaS, fintech, and AI
• Named fintech results
• Multi-market and multi-language experience
• AI search alongside SEO

Best fit: European fintechs investing in search across markets.

9. BrainDonors

Best for: European fintechs that want HubSpot, RevOps, and multi-channel marketing from one team at a manageable cost

BrainDonors is a B2B marketing agency founded in 2019 with offices in Sofia and Amsterdam. It is one of the larger HubSpot partners in Central and Eastern Europe, with about half its business outside the region. It reports more than 300 completed projects across B2B SaaS, AI, fintech, healthcare, and consulting, covering paid media, SEO including AEO and GEO, content, HubSpot implementation, marketing automation, RevOps, and web design.

For a fintech in this band, BrainDonors offers breadth under one roof: the CRM and automation, the website, and several acquisition channels. Reviewers frequently mention value for money, which matters at a stage where budgets are growing but still watched closely. In one published project, it migrated a data privacy software company from Pardot to HubSpot and rebuilt its marketing and sales operations.

It is not a fintech specialist, so companies should check its experience with regulated messaging in their segment.

Key services

• HubSpot implementation and RevOps
• Marketing automation
• Paid media and SEO, including AEO and GEO
• Content and social media
• Web design and development

Why BrainDonors stands out for fintech at this stage

• Broad execution from one team
• Strong HubSpot capability
• European presence and pricing
• Reviewers cite good value

Best fit: European fintechs on HubSpot wanting breadth at a reasonable cost. Less suited to those needing deep regulatory content expertise.

10. Right Left Agency

Best for: Payments and embedded finance companies whose priority is lowering acquisition cost and improving lead quality

Right Left Agency is a performance marketing agency focused on fintech scale-ups and B2B companies in regulated markets. It concentrates on lowering acquisition cost, shortening payback, and improving lead quality. Independent comparisons highlight its strength in payments and embedded finance, including marketing to both developers and business buyers.

For a payments or embedded finance company in this band, that dual audience is a real challenge. Developers decide whether an API is usable and business leaders decide whether to buy. Campaigns and pages need to work for both. Right Left's focus on acquisition efficiency also suits companies whose paid spend has grown faster than the returns.

Its emphasis is performance. Fintechs needing content depth or CRM work will need other partners.

Key services

• Performance marketing across Google, LinkedIn, and Meta
• Acquisition cost and payback optimisation
• Lead quality improvement
• Attribution for long sales cycles
• Landing page and demo flow optimisation

Why Right Left Agency stands out for fintech at this stage

• Focus on fintech and regulated B2B markets
• Experience with developer and business audiences
• Measured on acquisition efficiency
• Suited to scaling paid programmes

Best fit: Payments and embedded finance companies with growing paid budgets.

Why dimartec Approaches This Stage Differently

The nine other agencies cover the range of what a fintech in this band may need. CSTMR, Blue Train, and Curious Cat bring fintech credibility and messaging. Mint Studios, Perceptric, and Omnius build content and search. Evara and BrainDonors build the systems underneath. Right Left sharpens paid acquisition.

A fintech between €2M and €10M ARR usually needs several of these at once, and each specialist is accountable only for its own part. Content builds trust but cannot guarantee the right people see it. Paid campaigns reach buyers but convert poorly when the pages and proof behind them are thin. A well-built CRM records leads but cannot improve them. Meanwhile, the fintech's small marketing team spends its week passing briefs and reconciling reports between suppliers, while the board asks why acquisition costs are rising.

dimartec treats these as parts of one system. Performance Paid Media and GEO bring the right institutions into view. CRO turns visits into conversations with the information needed to judge fit. Lead Gen & Nurturing carries prospects through long, regulated evaluations. RevOps & Automation ties every source to revenue, so the company can show investors what its marketing produces. One team owns the whole, and the system is built for the client to run.

Three Things to Check Before Hiring a Fintech Marketing Agency

One: Ask for work from your segment. Payments, lending, wealth, insurance, and regtech have different buyers and rules. Ask for examples from clients in your segment, selling to the same type of institution, at a similar revenue level. General fintech experience is not always transferable.

Two: Ask how they handle compliance review. Find out how many review rounds their work typically needs with existing fintech clients, how they substantiate claims, and who checks technical accuracy. An agency that has not built this into its process will slow your marketing down.

Three: Ask how their work will show up in your board pack. Fintech sales cycles are long, so agree in advance which early measures, such as qualified opportunities with the right institutions, will show progress before revenue arrives, and confirm the agency can report them from your CRM.

Frequently Asked Questions

Do B2B fintechs need a fintech-only marketing agency?

Not always. Fintech-only agencies know the language and regulations, which usually means faster approvals and fewer errors. Broader B2B agencies can be equally effective if they have verifiable fintech work in your segment and a clear process for regulated content. What matters most is evidence: named fintech clients, compliance-approved examples, and results reported in pipeline.

Which marketing channels work best for B2B fintech between €2M and €10M ARR?

Most fintechs at this stage combine a fast channel with a slow one. Paid search and LinkedIn reach buyers quickly and can target institution types precisely. Expert content, organic search, and AI search visibility build credibility over months and keep producing. Industry events and partnerships matter more than in most software categories, because trust in financial services travels through networks.

How long does fintech marketing take to produce revenue?

Paid campaigns aimed at active buyers can produce conversations within weeks. Content and search usually take several months to build. Because many fintech sales cycles run for months and include security and procurement reviews, closed revenue from new marketing often appears six months or more after launch. Track qualified opportunities and progression through evaluation stages as earlier signs.

How should a fintech manage compliance review of marketing content?

Agree a simple process with compliance before campaigns start: which claims need evidence, who signs off, and how quickly. Keep a library of approved statements and proof points that can be reused. Agencies with fintech experience can draft within known constraints, which reduces the number of review rounds and keeps more of the message intact.

Earn Trust at the Speed Your Growth Plan Needs

Between €2M and €10M ARR, a B2B fintech has to win the confidence of institutions that have never heard of it, and do so faster than relationships alone allow. The right marketing partner helps the company look credible to strangers, reach the right institutions, carry them through cautious evaluations, and show investors exactly what that effort produces.

The Revenue Engine brings Performance Paid Media, CRO, GEO, Lead Gen & Nurturing, and RevOps & Automation together, built for B2B fintech and SaaS companies in this revenue band.
