Lean startup's hypothesis-driven experiments help less than a theory of what causes someone to buy, and followed alone they teach nothing.

Like Lean Startup, I think is Like the approach of being hypothesis-driven and like all, and kind of like running experiments and stuff like that is not a, it's a kind of approach. It's a method, but you need an underlying theory about what causes, what causes somebody to buy, what's important. And so I view it like, okay, cool. It's a, it's, it is a helpful thing, but it is not. It's not as important. And if you just follow it, you're going to do what everyone does, which is like you run a bunch of experiments and you don't learn anything.
