Where is this coming from? Sam does not have a "great" record as a CEO. In fact, he barely has any records. His fame came from working in YC and then the sky-rocketing of open AI. He is great at fundraising though.
the guy founded and was CEO of a company at 19 that sold for $43m
It is easy to sell a company for $43 if you raised at least $43. Granted, we don't know the total amount raised but it certainly it's not the big success you are describing. That and I already mentioned that he is good in corporate sales.
Which is a big part of being a great CEO
This isn't a success story, it's a redistribution of wealth from investors to the founders.
I'm curious - how is this easy?
