Product-market fit
The point at which a product solves a real problem for a large enough group of customers that they buy, use and recommend it without much pushing. Until a startup reaches it, spending heavily on growth makes little sense.

What it means
Product-market fit is the state in which a product solves a real problem for a large enough group of customers so well that they buy it, use it and recommend it without much sales pressure. The term is used mainly in the startup world, but it applies to any company launching a new product.
The path usually starts with an MVP, the simplest version of the product, which the company uses to test whether there is interest in the solution. Based on feedback, the product is refined until the value proposition fits the needs of a specific type of customer.
Product-market fit cannot be measured precisely by a single number, but it shows in the data: customers come back, churn falls, referrals grow and the sales cycle shortens. Until these signals appear, the company is looking for a market rather than growing in one.
How it works in practice
For startups whose books we keep, we help set up simple metrics that reveal product-market fit: repeat purchases, customer retention over time by cohort, and customer acquisition cost compared with customer value.
Financially, it is important that the company spends carefully before reaching product-market fit. Heavy investment in marketing and sales makes sense only once it is clear that customers want the product. Otherwise the company burns cash quickly and shortens its runway.
When the signals appear, it is time for a go-to-market strategy and scaling. This stage often coincides with a funding round, in which investors want to see precisely the evidence that the product has found its market.
What to watch out for
A common error is mistaking early interest for product-market fit. Enthusiasm from friends, positive reactions on social media or a few discounted pilot customers do not yet prove that people will buy the product at full price over the long term.
Nor is product-market fit permanent. Markets change, competitors arrive and customer needs shift. A company that once achieved it must keep watching its customers and their satisfaction, or it may lose its position.
