A neobank spends $25 to get someone to install its app. Roughly 60% of those people never finish signing up. Of the ones who do, a chunk pass identity checks but never link a bank account, and some link an account but never move a dollar.

This is the fintech , and where it leaks tells you more about future revenue than almost any other marketing number.
In retail, the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.View full definition → 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.

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.

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.
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:
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).

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.
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.
funnel_stage_conversion = users_reaching_stage_N / users_reaching_stage_N-1
# Example in plain terms:
kyc_pass_rate = kyc_passed / signup_started
account_link_rate = accounts_linked / kyc_passed
funding_rate = accounts_funded / accounts_linked
activation_rate = accounts_funded / kyc_passed # the one that predicts revenueTrack 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.

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 banking 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.
