The single most important metric for early-stage startups. Find out if users truly need your product before scaling.
The PMF (Product-Market Fit) survey, created by Sean Ellis, asks one powerful question:
"How would you feel if you could no longer use [Product]?"
Users choose from four options:
These are your core users. They can't live without your product. This is what you want.
They like your product but could find alternatives. Room to improve.
Your product hasn't become essential to them yet. Need to dig deeper.
Already churned or never activated. Different problem to solve.
The PMF Benchmark
40%+ "Very Disappointed" = Product-Market Fit
If 40% or more of surveyed users say they'd be "very disappointed" without your product, you've likely achieved product-market fit.
Scaling before PMF is the #1 startup killer. Don't pour fuel on a fire that isn't lit yet.
Follow-up questions reveal what "very disappointed" users love most. Double down on that.
Run PMF surveys quarterly. Watch your "very disappointed" percentage grow as you improve.
Your product hasn't found its audience or solved a real problem. Time to pivot or iterate significantly.
Some users love you, but not enough. Focus on understanding what the "very disappointed" users have in common.
You've built something people need. Time to optimize growth channels and scale. Congratulations!
