Product-Market Fit
A condition in which a product exactly meets a real need in a sufficiently large market. It is typically evidenced by metrics such as user retention, organic growth, and paid conversion, and is a key milestone in a startup's early stage.

Some senior engineers commented that when the main goal is to quickly validate product-market fit, choosing a proven simple solution is often the wiser decision.
If a product requires ever-increasing paid promotion to sustain growth and the share of organic growth (word of mouth, referrals) is extremely low, this is usually a strong signal of missing PMF.
Net Promoter Score (NPS) has blind spots in the PMF context, because users may be willing to recommend a product without actually depending on it.
Sapphire Ventures' partners advise that when PMF signals are unclear, rather than broadening features, it is better to focus on one niche scenario and deliver value to the extreme.
A founder who claims to have found PMF but has poor retention data is often more dangerous than a founder who admits fit has not yet been achieved but is iterating rapidly.
For a product with true PMF, its user retention curve flattens out after a certain point rather than continuing to decline to zero.
Product-market fit (PMF) is the watershed where a startup moves from early exploration to scaling, manifested as naturally rising user retention, shortened sales cycles and the emergence of word-of-mouth.
Product-Market Fit means the product precisely meets a real demand in a sufficiently large market, typically reflected in metrics such as user retention, organic growth and paid conversion.
The 40% rule proposed by Sean Ellis is used to quantify PMF: if more than 40% of users say they would be very disappointed if they could no longer use the product, the product has preliminarily achieved PMF.
