Free tool · Product-market fit
Do you actually have product-market fit?
Revenue is not fit. Mazo scores six signals — retention, organic pull, usage, expansion, the very-disappointed score and segment concentration — and returns a verdict: Pre-PMF, Approaching PMF, PMF or Strong PMF. Retention outranks the rest, so a growing number sitting on a declining curve gets told the truth.

Scoring your product-market fit — about 20 seconds…
How it works
- Answer what you know. Leave the rest blank — an unknown signal is itself a finding, and Mazo says what it would take to measure it.
- Get a verdict across six signals. Retention, organic pull, usage, expansion, the very-disappointed score and segment concentration.
- Unlock the diagnosis. The signal that decides it, what you are measuring wrong, the one number to move, and the test that settles it.
Mazo's rule of thumb: read the retention curve before anything else. A curve that flattens at any level means you have fit with the segment that stuck — go and find out who they are. A curve that declines to zero means no growth tactic will help, because it is a product problem.
Go deeper on product-market fit
Product-market fit is measured, not felt. Read how to measure product-market fit and activation rate, then check whether the segment that stuck matches your ICP. If the verdict is Pre-PMF, the first 10 customers plan is the right next move — not a channel.
FAQ
How do you measure product-market fit in B2B SaaS?
With behaviour rather than opinion. The strongest single signal is the retention curve: if it flattens at any level, you have fit with the segment that stuck. Supporting signals are customers arriving without outreach, usage frequency, expansion revenue, and the share of users who would be "very disappointed" without the product.
What is the Sean Ellis test?
A survey asking users who have actually experienced the product’s core value how they would feel if they could no longer use it. 40% or more answering "very disappointed" is the widely used threshold for product-market fit. Only survey people who reached value, and treat the number as noise when you only have a handful of customers.
Can you have revenue without product-market fit?
Yes, and it is common. Founder-pushed sales, pilots that never renew and enthusiasm without payment all produce revenue while retention decays underneath. That is why this scorecard weights retention above revenue and will overrule a strong growth number.
What should I do if the verdict is Pre-PMF?
Not scale. Adding channels or headcount against a decaying curve multiplies the leak. The scorecard names the single number to move and a test you can run in about two weeks to settle whether the problem is the product, the segment or the onboarding.
Fit first, then the plan
Mazo reads your numbers, tells you which stage you are really at, and builds the 90-day plan that fits it — then follows up every week to see whether it moved.
