Yep, agreed on the last slide that lean startup only works 1 out of 10 times

As opposed to?

Seriously, I'm not trying to be snarky. "Lean" is a way of thinking, a set of principles, etc. that should increase the odds of success of most startups. So if we say "using this only works 1 in 10 times" then how often do startups succeed who don't use them? And if one were to advocate for a "something else" model then what, exactly, is the "something else"?

Or I guess another way of wording what I'm asking is "Is there actually any counter-indication to doing things like getting to know your customers and understand their pains, achieving product / market fit before doing a big-bang PR launch, and waiting to try and massively scale sales and marketing until you know there is a market for what you're building"?
