Product-market fit is when a startup's product satisfies strong market demand. The most important milestone in a startup's life. GitDealFlow's engineering momentum data provides the objective signal layer.
Frequently Asked Questions
How do you measure PMF?
Sean Ellis Test: >40% 'very disappointed' if product disappeared. Other signals: organic growth, NDR >120%, low churn, and rising engineering velocity (GitDealFlow detects PMF via sustained commit velocity).
How long does it take to find PMF?
Most successful startups find PMF in 12-24 months. Some take longer. GitDealFlow's data shows teams that find PMF faster typically had higher engineering velocity from day one.
