What Is Product-Market Fit?
The point where your product satisfies strong market demand, evidenced by high retention, organic growth, and customers actively seeking you out.
Product-Market Fit Explained
Product-market fit is the moment when your product clicks with your market. Customers start telling other people about it. Retention improves. Growth accelerates without proportional increases in spending.
Marc Andreessen defined it simply: "Product-market fit means being in a good market with a product that can satisfy that market." You feel it when demand starts pulling the product forward rather than you pushing it.
Before product-market fit, growth feels like pushing a boulder uphill. Every customer requires convincing. Retention is low. Marketing spend produces inconsistent results. After product-market fit, customers start finding you, referrals increase, and the challenge shifts from finding customers to serving them.
The Sean Ellis test is the most common measurement: ask customers "How would you feel if you could no longer use this product?" If 40% or more say "very disappointed," you have product-market fit.
Why Product-Market Fit Matters
Spending on growth before product-market fit is the number one reason startups fail. You cannot scale something that does not work. PMF is the prerequisite for every growth investment: hiring, marketing, sales, and infrastructure.
Common Mistakes
- 1
Declaring product-market fit based on early adopter enthusiasm instead of mainstream adoption
- 2
Confusing product-market fit with product-founder fit (you love the product but the market does not)
- 3
Scaling marketing and sales before confirming retention metrics support PMF
