Most pre-launch advice is about product polish. The launch-jankiest rule is about reframing what the launch actually does. A janky MVP is not asking the market whether your product is good. It is asking whether the underlying problem is urgent enough that someone will tolerate an embarrassing version of the solution. If they do, the problem is real. If they walk because of the jank, the problem was probably a nice-to-have.
Tan's filter is concrete. You are not looking for a hundred users. You are looking for five or six:
It's more about filtering down those 100 into the five or six who actually have the problem you're addressing, who have such a hair on fire problem they might use your janky MVP solution. They might even feel empathy for your company.
That is the entire game in the first 90 days. Five customers with hair on fire teach you more than five hundred curious browsers. The hair-on-fire crowd will give you feedback that is actionable. The curious crowd will give you feedback that sounds smart and means nothing.
The trap founders fall into is treating the first launch as a one-time event with a permanent record. It is not. The launch is a probe. The market does not remember most startup launches and never will. The pressure founders place on launch day is a story they are telling themselves, not a fact about the world.
