How much time should a solo founder actually spend on competitive research before just building?
The short answer
As a rough starting point, cap the first pass at a few focused days: enough to know who the top three players are, roughly how they price, and what customers complain about. Anything beyond that before you have a prototype is usually procrastination dressed up as diligence, because the sharpest competitive insight comes after you're in the market and losing (or winning) real deals. Set a hard stop, write down what you learned, and go build.

Why we picked it
This is the canonical early-stage talk on where a founder's time actually pays off, and it keeps pulling you back to building something people want rather than studying the market from the sidelines. Altman is blunt that the work is making a product so good people tell their friends, which is a useful counterweight when you feel the urge to keep researching competitors. Treat it as a starting point for calibrating how little upfront analysis you really need before you ship.
Why we picked it
A VC names the exact failure mode a solo founder falls into: researching and deliberating so long that competitors ship while you optimize a spreadsheet. It puts a number on when to stop with the 70 percent rule, so you have a concrete cue that research has stopped paying off. Read it as a starting point for recognizing diminishing returns, not as permission to skip thinking entirely.
