I saw a new layer of founders - adherents of lean startup (by this term I mean all popular methodologies - business models, unit economics, customer development, etc.). These are founders who believe that there are methodologies that will lead to success without risk, you just need to conduct problem interviews correctly, then build business models correctly, test everything quickly and cheaply, and voila - you have a unicorn in your hands, preferably a dollar one. But it doesn't work that way!

Users in interviews don't give product recipes; they answer vaguely. In business models, everything is formulated easily, but in practice, such patterns cannot be found. Hypotheses are tested, but the problems of a cold start or a really expensive MVP ultimately prevent a quick and cheap launch.

So let's put an end to this discussion. All the methodologies taught in accelerators and lectures are certainly useful and do reduce risk, but not to zero, and not even to 50%; they reduce risk a little, allowing you to avoid the most novice mistakes. We even calculated - in an accelerator, the survival rate is around 15-17%, and if you look at all startups without acceleration and training, the survival rate is about 4-5%. But once the theoretical foundation is covered, you still have to face risk, you still have to raise money and invest it, you will still encounter a huge number of difficulties and situations where it is unclear how to act - this is the basis of entrepreneurship and startup management, and no lean startup can overcome it.
