So much this. There is a very big difference between running a startup and a large / publicly traded company. There is no shame in a founder hiring a good ceo to manage the company after the startup phase. I worked for a company where they essentially grew through grit and insane hours and became established and went public. Then everything started going to hell. CEO was just not prepared to run a proper company and as a result constant production crashes, employee and customer churn. Company survives by constantly diluting and selling more shares now.
But that's also extremely risky, it's really not easy finding good CEOs and not easy to tell if one is going to be good or not (see Apple replacing Jobs in the 80s).
This. The things that get a start-up to IPO are not what make a successful company after IPO. Different leaders are needed, Google succeeded by bringing such a CEO on bord. It is hard to see companies on a good trajectory, from start up to mature public entity, fail due to these purely self inflicted things.
