Finding customers and growing
Product-market fit
Product-market fit (PMF) is when a clear group of people keep using your product and would miss it if it disappeared, shown by what they do, not what they say.
Also called PMF, product market fit
Looking this up for a class, a job, or something you want to build? If it is the last one, nommi reads your idea before you spend months on it.
It shows up as evidence: users coming back without reminders, paying without long persuasion, and telling others. Polite praise, sign-ups that never return, and friends' encouragement are not evidence of it. Fit is reached with a specific group first, not with everyone at once.
What recent RevenueCat data says
Results split widely even among subscription apps that already charge: in RevenueCat's 2026 report, the top quarter grew monthly recurring revenue 80% in a year, while the bottom quarter shrank 33%. The report does not measure fit.
- Yearly change in monthly recurring revenue, top quarter against bottom quarter of subscription apps: up 80% against down 33%.
Source: RevenueCat, State of Subscription Apps 2026. More than 115,000 subscription apps on RevenueCat, not all apps. As of 5 November 2026.
When this shows up
Example, not a real founder: your launch post brings a wave of sign-ups and kind comments. A few weeks later, almost nobody is still using the app. The attention was real, but fit was not there yet.
What to do next
Pick one group of users and count how many came back on their own last month. Talk to the ones who did, and ask what they would use if your product vanished. If those counts and conversations tell you to start over, Idea Finder suggests a new direction from your background, skills, hours and budget.
