In retail, the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.Voir la définition complète → is: visit, add to cart, purchase. In fintech, there's a regulatory checkpoint baked in: KYC (Know Your Customer), the identity verification process mandated under anti-money-laundering law, in the US primarily the Bank Secrecy Act enforced via FinCEN, and in the EU under the Anti-Money Laundering Directives (AMLD) enforced by national regulators.

The four core stages

2. KYC pass. User submits ID (often a driver's license photo plus a selfie for liveness matching) and passes identity verification. This is the first real filter. Failure here isn't just UX friction, it's regulatory necessity: firms cannot legally onboard a customer without it.

3. Account link. User connects a funding source, typically a bank account via an account-aggregation APIAPIApplication Programming Interface: a standardised interface that lets applications communicate and exchange data without knowing each other's internal workings.Voir la définition complète → (Plaid in the US, Tink or similar open bankingopen bankingCadre réglementaire (PSD2 en Europe) obligeant les banques à partager les données clients via des API standardisées, avec consentement, transformant les données bancaires en actif compétitif. providers in the EU under PSD2, the EU's Payment Services Directive 2, which mandates banks expose account data to authorized third parties).

4. First funding. User actually moves money, a deposit, a transfer, a paycheck via direct deposit. This is the moment a "user" becomes a "customer" in any meaningful commercial sense.

Where the real drop-off happens

Industry data on neobank onboarding (aggregated from public reporting and product benchmarking firms like Mixpanel and Amplitude, figures below are estimates as of 2025 and vary widely by product) suggests a rough shape:

• Install to started signup: 70 to 85% (estimate)
• Started signup to KYC pass: 55 to 75% pass on first attempt (estimate); a meaningful share fail on document quality or name-matching mismatches
• KYC pass to account link: 60 to 80% (estimate); this is where "I'll do it later" behavior spikes
• Account link to first funding within 30 days: 40 to 65% (estimate)

Multiply those through and you can see how an app with a million installs might end up with well under 150,000 genuinely funded accounts. Each stage has a different owner and a different fix: KYC drop-off is often a product/compliance problem (bad camera UX, unclear rejection reasons), account-link drop-off is often a trust problem (users hesitate to hand over bank credentials), and funding drop-off is often an incentive problem (no compelling reason to move money today rather than next month).

The metric that actually predicts revenue

But the stage that correlates most tightly with revenue is KYC-to-funded conversion, sometimes called "activation rate."

Worked example:

Say a fintech runs a campaign generating 10,000 installs at a blended cost per install of $20, so $200,000 total spend.

• 7,000 start signup (70%)
• 4,200 pass KYC (60% of those who start)
• 2,940 link an account (70% of KYC passers)
• 1,617 fund an account within 30 days (55% of linkers)

KYC-to-funded rate = 1,617 / 4,200 = 38.5%

Blended CAC per funded account (customer acquisition costcustomer acquisition costCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period.

This is why sophisticated fintech marketing teams report activation rate to the board, not just install counts or app store rankings.

A simple way to instrument this

Track each rate weekly by acquisition channel (paid social, referral, organic, affiliate). A channel with cheap installs but poor KYC-to-funded rates is often a false economy, common with incentivized "sign up and get $5" affiliate traffic that drives volume without intent.

US vs Europe: structural differences worth knowing

In the US, KYC friction tends to concentrate around document verification (state-issued IDs vary enormously in format, causing OCR, optical character recognition, errors) and Social Security Number matching.

In the EU, PSD2's open bankingopen bankingCadre réglementaire (PSD2 en Europe) obligeant les banques à partager les données clients via des API standardisées, avec consentement, transformant les données bancaires en actif compétitif. mandate means account-linking conversion is often *higher* than in the US, because bank-to-bank data sharing is standardized and regulator-enforced, whereas in the US it still runs through aggregators like Plaid negotiating individual bank relationships. This is a real structural reason EU neobanks (Revolut, N26, Bunq) sometimes report smoother account-link stages than US counterparts, though exact comparative figures are not consistently published and should be treated as directional, not precise.
