Most of the leadership advice available to a woman founder was written by, and for, someone who never had to prove they belonged in the room in the first place. That gap shows up in small but costly ways: coaches who mistake a founder's caution for lack of confidence, advisors who can't tell the difference between a real risk and an inherited one, board members who read decisiveness in a woman as recklessness when they'd read the identical call in a man as strength.
