PMF
Product-Market Fit
The point at which the market pulls product out of you faster than you can build it. Until you feel that pull, you do not have PMF.
Product-Market Fit is famously hard to define and famously easy to recognise. Marc Andreessen’s heuristic still holds: you know you have it when the product is being pulled by users, the press, and the cap table all at once, and your problem is no longer how to find customers but how to keep up with them.
Pre-PMF, almost everything you do is a bet. The right org chart, the right tech stack, the right hiring plan all depend on which segment of customers actually pulls. Post-PMF, the questions become operational: scale the team, harden the stack, control the burn.
The reason this matters for engineering decisions: a pre-PMF team that over-builds for scale is wasting runway. A post-PMF team that under-builds will be eaten by its own success. Wavect engages differently across this line. Pre-PMF: ship the cheapest version that lets you learn. Post-PMF: harden, document, and start sleeping at night.
