Product-Market Fit

The point at which a product clearly satisfies strong demand from a defined group of customers, shown by retention, organic growth and willingness to pay.

Example

Most customers renew, new customers arrive through referrals, and demand outpaces the team's capacity.

Important

It is shown by customer behaviour over time, not declared in a pitch.

Lessons that explain it

• Team, market, product, business - and why the order matters — At the earliest stage there is little business to analyse, so evaluation leans on the team and the market. As a company matures, the evidence shifts toward product and business fundamentals. (10 min)
• Ask why now, and what stops the next ten companies — Evaluating competition means understanding why this opportunity exists now, who else can serve the customer, and what would make this company hard to displace once it is working. (11 min)
• A startup is a search for a business model, not a small company running one — A startup is designed to grow very fast by finding a repeatable, scalable business under deep uncertainty. That purpose is why it behaves, fails and is valued so differently from an ordinary small business. (9 min)
• Each funding stage buys proof of something specific — Pre-seed, seed, Series A, Series B and growth rounds each fund a different milestone. Knowing what a stage is meant to prove tells you what evidence to expect at that stage. (11 min)
• Product-market fit shows up in behaviour, not in enthusiasm — Product-market fit means a specific group of customers needs the product badly enough to keep using it, pay for it and recommend it. It is visible in retention and organic demand, not in praise. (10 min)
