1:49Elad Gil: When do you know you have Product Market Fit?
From Y Combinator · Published Jul 22, 2019 · Watch on YouTube
TL;DR
Elad Gil defines product-market fit (PMF) through three observable signals: users staying with a broken product (e.g., Twitter’s “fail whale” era), major brands organically discovering and paying for a SaaS product (e.g., PagerDuty, Zeplin, Airtable), and extremely strong customer feedback (e.g., “love letters” at Color).
Key insights
- A product that is broken yet retains active users is a clear, raw indicator of market adoption.
- For SaaS companies, unsolicited adoption and payment by large, well-known brands is a concrete PMF signal.
- Emotional, unsolicited customer testimonials — even from a small group — can be a strong PMF sign, as seen at Color where customers credited the service with saving lives.
