Verdict
Emerging — don't floor it yet
Scale readiness
Some fit, but not enough to floor the acquisition budget. Scaling now amplifies a leaky funnel. Fix the weakest signal — usually retention or organic pull — before spending harder.
Retention and the "very disappointed" test predict PMF better than growth rate — a leaky product can grow fast on paid spend and still lack fit.
About this calculator
Score the signals that actually indicate product-market fit — the very-disappointed test, retention flattening, organic pull and NPS — into one readiness grade.
