Fintech has a measurement quirk no other category shares quite so sharply: a huge share of your signups never become users at all. KYC checks, funding steps, and approval flows mean a long gap between "created an account" and "actually uses this for money." Measure PMF across everyone and you'll drown the signal.
The target is the usual one — 40% "very disappointed" — but getting an honest read depends entirely on surveying the right accounts.
Is the PMF benchmark different for fintech? No — it's still 40%. What changes is that you only count accounts that have actually moved money.
Who counts as an engaged user in fintech
An engaged fintech user is a funded, active account — someone who has completed onboarding, passed KYC, and used the product for a real transaction. Signups stuck in the activation funnel aren't telling you about product-market fit; they're telling you about your onboarding. Keep those two questions separate.
The trust factor
In most products, "very disappointed" means a workflow gets harder. In fintech, it usually means something deeper: I trust this with my money and I don't want to move it. Switching a financial product is painful and a little scary, so a user who'd be genuinely disappointed to lose you has handed over real trust. That makes a strong fintech score especially load-bearing — and a weak one a warning that you're a convenience, not a home for someone's money.
Nubank measured it
Nubank, one of the largest digital banks in the world, has talked about using the Sean Ellis "very disappointed" score as a key input when deciding whether to invest in new products. If a survey-based PMF score is good enough to steer product strategy at that scale, it's good enough for an early-stage fintech deciding what to build next.

- Survey funded, active accounts only. Exclude signups stuck in onboarding — they measure your funnel, not your fit.
- Separate activation from fit. Low activation is an onboarding problem; a low score among active users is a product problem. Don't conflate them.
- Read the "why" for trust signals. Open-ended answers about safety, control, and reliability are gold in fintech — they're your positioning.
- Track it over time. Trust compounds. A rising score is the cleanest evidence your financial product is becoming a default, not a trial.
The 40% line is the same. The discipline fintech demands is being ruthless about who you survey — because a financial product's signup list and its real user base are two very different things.
