Mark Zuckerberg

Refusing to sell, then locking in control. Zuckerberg turned down Yahoo's offer of about a billion dollars for Facebook in 2006, when the site was two years old, against the wishes of some investors and staff. At the 2012 listing he kept control through shares carrying ten votes each, so outside shareholders cannot remove him. Independence let him make huge bets such as the metaverse spending, with little check from investors.
