Product-Market Fit for Founders
DIRECT ANSWER
Product-market fit is the state in which a product satisfies strong, repeatable demand from a well-defined market segment.

What product-market fit means for Founders
Founders are doing marketing at the edge of their expertise, with no time to learn it deeply. They need execution, not education. The cost of inconsistent marketing compounds — dead brand, dead SEO, dead pipeline.
For a founder, product-market fit is a lever you need but rarely have time to execute consistently. The most widely used quantitative signal is the Sean Ellis test: survey active users and ask how disappointed they would be if the product no longer existed. A 'very disappointed' rate above 40% correlates strongly with durable growth. Below 25% is a clear signal to iterate. Retention curves that flatten rather than drain to zero are a complementary structural sign — if a cohort stabilizes at 20–30% weekly retention after the first month, the product is holding a real audience.
