Heads of several other tech companies sit on Facebook’s board of directors, with the stock shares to show for it. Reid Hoffman, the majority stakeholder of LinkedIn, invested in Facebook during an initial round of fund-raising as early as 2004, when the site was still in its infancy. He is estimated to have a stake of 0.5 percent, which means he would make $500 million on the IPO. Mark Pincus, cofounder of the gaming company Zynga, was another early investor, with a similarly valued stake. Both LinkedIn and Zynga recently launched their own IPOs, which means the two men are just building on their already considerable fortunes.
Other CEOs set to make some more bank: Netflix head Reed Hastings owns about 20,000 shares; Washington Post CEO Don Graham reportedly holds 1 million shares.
