Most founders read the PMF survey as a single number: are we above 40% or not? That number matters, but it's the least useful output of the survey. The real gold is the segmentation, the three groups the survey sorts your users into, each of which is telling you to do something completely different.
| Segment | What it is | The action |
|---|---|---|
| Very disappointed | Your core market and evangelists | Understand them, find more like them |
| Somewhat disappointed | Blocked fans, the growth lever | Remove the specific barrier |
| Not disappointed | The wrong-fit segment | Ignore their roadmap requests |
Very disappointed: your core market
These are the users who would be genuinely upset to lose you. Their share is your PMF score. The action here isn't to change anything for them, it's to understand them so precisely that you can find and acquire more people exactly like them.
Read their answers to "what type of person would most benefit?" and "what is the main benefit you get?" Those answers hand you your ICP and your core value proposition, in the market's own words. This is the segment that built Superhuman's 22%-to-58% climb: they doubled down on the people who already loved it.
Somewhat disappointed: your growth lever
These users see value but something holds them back from loving you. They are the single biggest lever on your PMF score, because converting "somewhat" to "very" raises the numerator directly. Read their answers to "how can we improve this for you?" and you get a prioritized barrier list, straight from the people most likely to move.
The discipline: look for the barrier that repeats across many of them, not the loudest single request. A theme that shows up 15 times is a roadmap item. One vivid complaint is an anecdote.
Not disappointed: the wrong fit
These users wouldn't miss you. It's tempting to treat their feedback as a to-do list, if we just built what they asked for, they'd love us. This is a trap. Building for the not-disappointed segment pulls your product away from the people who love it and toward people who never will. Their requests will mislead your roadmap.
The right action is usually to exclude them, both from your roadmap and, often, from your acquisition. They're not your market.
Get your segments, not just your score
PMFtracker splits every response into the three segments automatically and analyzes the open-ended answers, so the action for each group is obvious. Run it free.

The instinct is to fix the unhappy people, the not-disappointed group. The math says otherwise. Your PMF score rises fastest when you convert somewhat-disappointed users to very-disappointed, because those users already see value; you're removing a blocker, not manufacturing desire from scratch. Serve your core better to keep them, remove barriers to convert the middle, and let the wrong-fit segment go. That's the entire segmentation playbook.
Turn three segments into three action lists
PMFtracker calculates your PMF score, sorts every respondent into the three segments, and surfaces the themes in their answers, so you always know who to serve, who to convert, and who to ignore.
