Early Traction

There is a moment when a product stops being something the team pushes on the market and starts being something the market pulls out of the team’s hands. That moment — product-market fit — is the single most important thing to reach and the most commonly misread. Early enthusiasm from a handful of unusual users feels identical to the beginning of real demand, and the difference between them is the difference between a company and an expensive hobby.

This part of the lifecycle is about generating, reading, and acting on early signal. It covers what product-market fit actually means (and why its two most-cited definitions diverge), what a minimum viable product is for (a learning instrument, not a cheap product), and the build-measure-learn loop that turns a vague hunch into a decision to persevere or change course. It covers customer discovery done honestly, the structural gap between early adopters and the mainstream market that kills companies who mistake one for the other, and the disciplined change of direction — naming which kind — that follows when the signal says the current path is wrong.

The hard part is interpretation. Early adopters have a higher pain threshold, more patience for rough edges, and different needs than the customers who come after them; reading their love as proof of mainstream demand is one of the most expensive mistakes a founder can make. The entries here give names and tests to the signals worth trusting and the ones worth distrusting.

Reaching genuine traction does not end the work, but it changes its nature: from searching for a viable model to scaling one. Knowing which side of that line you are actually on is what this part of the book is for.
