I think Marc Bodnick probably nailed it.
More generally, very charismatic CEOs doing something that sounds disruptive with social proof (e.g., famous angels) … can recruit really amazing people to the board if they really work at it.
Mentoring people is a natural human instinct in many successful leaders.
A super charismatic CEO, in a potentially disruptive space, asking for mentorship (along with 0.5-1% of the company for it) … someone great will take that offer.
