Paid acquisition used to be the easy lever. A fintech would set a budget, run ads across Google and Meta, and watch the sign-ups come in. That lever has got a lot harder to pull. Costs have climbed, ad platforms have tightened targeting rules under GDPR and the ePrivacy rules, and users have grown sceptical of anything that looks like a banner ad. So growth teams across Europe are going back to something older and, in many ways, more durable: partnerships.
A well-built affiliate partnership strategy gives fintechs a way to acquire customers through trusted voices instead of paid impressions. Comparison sites, finance bloggers, YouTubers, newsletters and even other fintechs recommend a product because their audience already trusts them. The fintech pays only when that trust converts into a lead or a customer. It’s a model built around accountability rather than reach, and that’s exactly why it’s making a comeback.
This article looks at why partnership networks are becoming central to European fintech growth, how the commission structures actually work, what a proper rollout looks like, and the mistakes that trip up even well-funded teams.
Why paid acquisition alone stopped working
Three things changed at once, and none of them are temporary.
First, privacy regulation reshaped what marketers can track. Post-GDPR and with browsers phasing out third party cookies, attribution has become messier. A fintech can no longer assume it will know exactly which ad drove which sign-up, which makes every euro of ad spend harder to defend internally.
Second, customer acquisition costs in financial services have risen steadily as more fintechs compete for the same pool of digitally engaged consumers. Investment platforms, digital banks and lenders are all bidding on similar keywords and similar audiences, which pushes prices up for everyone.
Third, trust has become the actual bottleneck. Financial products are not impulse purchases. Someone comparing lending platforms or investment apps wants a second opinion before they hand over their bank details. That’s precisely the gap affiliates and partners fill: they’ve already done the research, or their audience believes they have.
None of this means paid media is dead. It means it’s no longer sufficient on its own, and fintechs that relied entirely on it are now looking for a second, more resilient growth channel.
What is an affiliate partnership strategy?
An affiliate partnership strategy is a structured plan for recruiting, managing and paying external partners, such as content publishers, comparison sites and finance influencers, to promote a fintech product in exchange for performance based compensation.
Unlike a one off affiliate sign up, a proper strategy sets out who the ideal partners are, which commission structure fits each product, how compliance is enforced across every partner’s content, and how performance is tracked and optimised over time.
The difference between fintechs that get real value from partnerships and those that don’t usually comes down to whether they treated it as a strategy or as a checkbox. A checkbox approach means signing up for a network, uploading some banners, and hoping something happens. A strategy means someone owns the channel, sets targets by partner tier, and actively manages relationships the way a sales team would manage key accounts.
The commission models fintechs are actually using
Commission structure is where a lot of partnership programmes quietly fail. Get it wrong and you either overpay for low quality leads or underpay the partners capable of sending your best customers. Three structures dominate serious fintech programmes in Europe right now.
CPA (cost per action) works well for products with a clear, singular conversion point, such as opening an account or completing a first transaction. It’s simple to explain to partners and simple to budget against, which makes it a good fit for broad acquisition campaigns.
CPL (cost per lead) is the standard in lending, insurance and brokerage, where the value of a customer only becomes clear after underwriting or onboarding. Paying per qualified lead lets the fintech control quality at the point of payment rather than trying to claw back commissions later.
Hybrid (CPL plus CPS) tends to suit higher value products such as P2P lending, investment platforms and brokers, where the real value of a customer plays out over months rather than at sign up. In practice this means a fixed CPL paid upfront, plus a CPS earned on the lead’s transaction volume in the first 90 to 180 days after registration, usually alongside a fixed fee for any content production the partner does. This structure rewards partners for sending genuinely engaged customers rather than just warm bodies.
| Model | Best suited to | How it’s paid | Main advantage |
| CPA | Broad acquisition, digital banking, payment apps | Fixed amount per completed action | Predictable, easy to scale |
| CPL | Lending, insurance, brokerage | Fixed amount per qualified lead | Quality control before payment |
| Hybrid (CPL + CPS) | P2P lending, investment platforms, brokers | CPL upfront, CPS on transaction volume for 90–180 days | Aligns partner incentives with long term customer value |
A practical note from managing these programmes: fintechs often default to CPA because it’s the easiest to model in a spreadsheet, even when their product would benefit more from a hybrid structure. If your average customer only becomes profitable after several months of activity, a flat CPA payment gives partners no reason to prioritise quality over volume.
Building a partnership network: what actually works
Recruiting partners is the visible part of the job. The less visible part, and the part that determines whether the programme survives past year one, is everything that happens afterwards.
Start with partner segmentation, not partner volume
A common early mistake is chasing partner count as a vanity metric. Fifty inactive affiliates on a dashboard look impressive in a board deck and generate almost nothing. It’s far more useful to segment potential partners into tiers, comparison sites and finance media, content creators and niche bloggers, and other fintechs or complementary platforms, and build a distinct approach for each. A comparison site needs accurate, regularly updated product data. A content creator needs creative freedom within compliance limits. A complementary fintech partner might work better as a co-marketing arrangement than a pure affiliate deal.
Give partners something worth promoting
Partners promote what converts. If your onboarding flow is clunky or your product page buries the pricing, no commission structure will fix that. Before scaling recruitment, it’s worth auditing the actual landing experience a referred user hits, because partners will quietly stop sending traffic to a page that doesn’t convert, long before they tell you why.
Treat compliance as part of the offer, not an afterthought
Financial promotions carry regulatory weight that a lifestyle brand’s affiliate content doesn’t. Under the Unfair Commercial Practices Directive, undisclosed affiliate relationships can be treated as misleading commercial practice, and for investment products, MiFID II requires that marketing communications are fair, clear and not misleading, an obligation that extends to how partners describe the product, not just how the fintech itself describes it. Giving partners pre-approved disclosure language and clear content guidelines from day one avoids a much more painful compliance clean up later.
Track beyond the first conversion
A fintech that only measures sign ups is measuring the wrong thing. What matters for a hybrid CPL plus CPS model, in particular, is whether partners are sending customers who actually transact, stay active, and don’t churn within the first quarter. That data should feed back into which partners get more budget and which get cut.
Where fintechs go wrong
Most partnership programmes that underperform share a small set of recurring problems.
- Treating the affiliate network sign up as the finish line rather than the start of active partner management
- Using a single commission model across every product type instead of matching the model to customer lifetime value
- Under-resourcing partner communication, so high performing affiliates drift toward competitors with better support
- Ignoring compliance training for partners until a regulator or a network raises it
- Measuring success purely on volume of sign ups instead of retained, revenue generating customers
The pattern behind most of these is the same: partnerships get set up as a project, then left to run themselves. A partnership channel behaves more like a sales pipeline than a media placement, and it needs ongoing management to keep performing.
Compliance considerations for European partnership programmes
Financial services marketing sits under tighter scrutiny than most sectors, and that scrutiny extends to affiliates acting on a fintech’s behalf. A few frameworks come up repeatedly when structuring a compliant programme:
- MiFID II governs how investment products are marketed, requiring communications, including those from affiliates, to be fair, clear and not misleading, with oversight from ESMA and national regulators.
- The EU Consumer Credit Directive sets standards for how credit and lending products can be advertised, which matters directly for CPL programmes in that space.
- MiCA applies where crypto-asset products are being promoted through partners.
- The Unfair Commercial Practices Directive requires that affiliate relationships and sponsored content are clearly disclosed to consumers.
- GDPR and the ePrivacy rules govern how partner tracking, cookies and consent are handled across the customer journey.
None of this should discourage a fintech from building a partnership channel. It just means the programme needs proper governance built in from the start, rather than treated as a marketing side project that legal reviews only when something goes wrong.
Bringing it together
Partnership networks aren’t replacing paid media, they’re compensating for what paid media can no longer do on its own: deliver trusted, cost accountable growth in a market where attribution has got harder and customer acquisition costs keep climbing. The fintechs seeing real traction with this channel share a few habits. They pick a commission model that matches how their product actually generates value, whether that’s straightforward CPA, quality focused CPL, or a hybrid structure for higher value products. They manage partners actively instead of setting up a network and walking away. And they bake compliance into the partner relationship from the outset rather than retrofitting it.
This is where specialist support tends to pay for itself. Building and running a compliant, well-segmented partner network across multiple European markets is a full time discipline, one that touches affiliate program management, publisher recruitment, and ongoing performance optimisation all at once. Circlewise works with fintech and financial services brands to build exactly this kind of network, from identifying the right publisher mix through to structuring commission models that reflect genuine customer value rather than just first click volume. For fintechs weighing up where to invest next, a properly resourced publisher recruitment process is often the fastest route back to predictable, compliant growth.
Frequently asked questions
What is the difference between an affiliate partnership strategy and a traditional referral programme? A referral programme typically rewards existing customers for recommending a product to friends or contacts. An affiliate partnership strategy recruits external publishers, comparison sites and content creators who promote the product to their own audience, usually under a formal, performance based commission agreement.
Which commission model should a lending fintech use? CPL is the standard for lending, since customer quality only becomes clear once a lead has gone through underwriting. A hybrid CPL plus CPS structure suits P2P lending platforms specifically, where transaction volume in the months after registration is a better indicator of value than the initial lead itself.
Do affiliates need to disclose their relationship with a fintech? Yes. Under the Unfair Commercial Practices Directive, failing to disclose an affiliate or sponsorship relationship can be treated as a misleading commercial practice, which puts both the affiliate and the fintech at risk.
How long does it take to build a working partnership network? Recruitment can move quickly, often within a few weeks for the first wave of partners, but a network that consistently delivers quality customers usually takes several months of active management, testing commission structures and refining which partner types perform best for a given product.
Can partnership marketing work for early stage fintechs with limited budgets? Yes, and it’s often a more capital efficient channel than paid media for early stage companies, since spend is tied to performance rather than impressions. The main constraint isn’t budget, it’s having the internal capacity to manage partner relationships properly.
What makes a comparison site a good partner for a fintech? Comparison sites tend to convert well because users arrive already in a decision making mindset. The best partnerships come from sites with accurate, regularly updated product data and a readership that matches the fintech’s target customer, rather than sites with the highest raw traffic.
How does GDPR affect affiliate tracking? Affiliate tracking that relies on cookies or similar technologies needs a valid legal basis and, in most cases, user consent under GDPR and the ePrivacy rules. Fintechs should ensure their tracking setup, and any partner facing tracking pixels, are built with this in mind from the start.
Is revenue share a common commission model in fintech affiliate marketing? It’s less standard in fintech than in some other sectors. Most established programmes structure commissions around CPA, CPL, or a hybrid CPL plus CPS model tied to defined lead and transaction milestones, which gives both the fintech and the partner clearer, more predictable terms than an open ended revenue split.
