That's why the pressure is so great on him.
EDIT: you guys don't like this comment. Let me generalize.
- Facebook is a bad example because it reached a 50B valuation in private equity deals.
It's better if you mention a company that has already IPO'd, been sold outright (founder not involved anymore), or has lower-valuation equity deals, so that the founder is not under as much pressure.
I would not like to be in the position of figureheading such a company pre-IPO.
This is just my personal taste. Please don't think that I'm trying to be prescriptive. You can trade places with Mr. Zuckerberg if you like. I'm just giving you my thoughts of a better example.
I give up, you guys clearly don't like my impressions of the pressure on him. I guess we'll just have to agree to disagree.
