Product-market fit
What is product-market fit?
Product-market fit (PMF) is the point at which a product meets a strong need in a well-defined market, so that customers want it, keep using it and recommend it, and growth starts to come more easily. The phrase is closely associated with investor Marc Andreessen.
There is no single test. Common signals are strong retention, organic word of mouth, customers who would be very disappointed without the product, and sales cycles getting shorter.
Why product-market fit matters
Before product-market fit, the job is learning: talking to customers and changing the product. After it, the job is scaling. Spending heavily on growth before fit usually burns money.
How to find product-market fit
- Pick a narrow beachhead market.
- Talk to potential customers about their problem before and while building (customer discovery).
- Ship a minimum viable product and get it into users’ hands.
- Measure retention and ask users how they would feel if it went away.
- Iterate on the product, the audience or the positioning until retention and referrals hold.

How do you know you have product-market fit?
Look for retention that flattens instead of falling to zero, customers who pull the product into their work, growing word of mouth, and a clear answer to who it is for. If you have to ask, you probably are not there yet.
