Yeah, then the investors call a board meeting and bring in a new CEO to provide adult supervision after a 2/3rds vote. The give that guy more equity than you to keep the ship afloat. "It's not your company anymore."
I’m not sure where that’s coming from.
Also plenty of companies out there have control past the A.
And in the best case it’s just one series A taking ~15%, thus founders still have 85%
Equity ownership and voting control are also different things. After the B you commonly have 2 investors and an independent director on the board, alongside 1-2 founders.
