Stop guessing if you have PMF
Product-market fit isn't binary—it's a spectrum. SprintUX helps you measure where you are, identify gaps, and know exactly what to fix.
The PMF measurement problem
“You'll know it when you feel it” isn't a strategy. Most founders can't tell if they're close to PMF or miles away because they lack systematic feedback. SprintUX makes PMF measurable.
Measure the signals that matter
Customer Pull
Are customers seeking you out, or do you have to push? PMF means organic demand.
Retention & Usage
Do customers come back? High retention is the clearest sign of product-market fit.
Word of Mouth
Would customers recommend you? Track NPS and referral sentiment over time.
Willingness to Pay
Do customers value your product enough to pay for it? Validate pricing and packaging.
“Our investor said our customer research was 'unusually rigorous for a seed-stage company.' SprintUX helped us prove PMF with data, not just vibes.”
Sean Ellis PMF survey, automated
We've built the classic PMF questions into our AI—plus follow-ups that dig deeper into why customers feel the way they do.
- “How would you feel if you could no longer use [product]?”
- “What would you use as an alternative if this didn't exist?”
- “What's the main benefit you get from using [product]?”
- “Who do you think would benefit most from this?”
- “What would make this a must-have instead of nice-to-have?”
