Month one, everything was fine. That is the part nobody warns you about.
Here is the shape of it, and if you have shipped anything you already know where this goes.
Month one, it works. You demo it, people nod, it feels fast. Month two, real users arrive, you fix small things, still fine. Month three, a change that should take a day takes a week and nobody can quite explain why. Month four, the person who built it has moved on, the only one who understood the data model is not answering, and every change carries a risk nobody can size.
Notice what did not happen. Nothing broke.
Software rarely fails in a way you can point at. It gets expensive to touch, then frightening to touch, then it stops changing at all, and for a startup a product that cannot change is the slow version of dying.
The cause is almost never code quality. Good engineers wrote it. It is that the build had one function and needed five.
Nobody owned the what. Nobody owned how it should feel. Nobody proved it held. Nobody was still attached to it in month four.
You can survive missing one of those for a while. Missing four is the timeline above.
Where did your month four land?
