Jumping from FAANG to startup

Jumping ship from big corporations and going to a startup seems ideal. You can can grow an organization underneath you, there is no need to play these games as with smaller teams the ability to see impact is greater. But ultimately a company can only scale to the managerial ability of its leadership. So if you haven't learned how to be a leader, how to be a manager, you won't be able to grow the business effectively. Corporations provide a training ground, with clearly defined rules (just not written down anywhere), but once you know the game, you can be effective at playing it.
