Frequently asked questions
What does the PMF Evidence Gap Finder calculate?
It calculates a weighted 0-100 confidence score from four workflow-specific factors: demand evidence, activation evidence, retention evidence, revenue and referral evidence.
How should I choose each rating?
Use 1 for an untested assumption and 5 only for repeated, recent evidence from relevant customers. Conservative ratings make the next-step recommendation more useful.
Is this result proof of product-market fit?
No. It is a structured planning signal based on your inputs, not a substitute for interviews, observed behavior, retention, revenue, or statistically appropriate experiments.
Is entered information uploaded?
No. The calculation runs in your browser. Avoid entering confidential, personal, or commercially sensitive information.
