In its near 400-page S-1 filing for an initial public offering, Facebook had to reveal not only details about its revenue figures but also the now well-known names that helped build the social network from a dorm room side project into a global company. Not all of them are flattering. We knew that Sean Parker likes to party and Mark Zuckerberg has a dog. But did you know that Facebook can't live without Sheryl Sandberg?

Mark Zuckerberg is now at the mercy of stockholders. The IPO filing concedes that the 27-year-old has "control over key decision making" thanks to his controlling share of the stock. Facebook also paid Zuckerberg a (somewhat paltry) $703,833 in salary last year -- with stock, the number is about double at $1,487,362 -- but that will be reduced to $1 in 2013. That said, since he owns 28.4 percent of the company, he can just sell a few shares if and when he feels low on cash. 

Sheryl Sandberg is one of two "key personnel" whom if lost, "could harm [Facebook's] business." (The other one is easy to guess.) For her efforts, Sandberg earned $318,966 in salary from Facebook, but with her 1,899,986 Class B shares and 39,321,041 in stock options, her total shares are probably worth about a billion bucks. 

Donald Graham, the head of The Washington Post Company and CEO mentor to Zuckerberg, did not make that much money for serving on the board of directors in 2011: $16,667 and no stock. (Peter Thiel earned the same.) By comparison, LinkedIn co-founder Reed Hastings earned the same dollar amount but got 593,400 shares of stock for his role on the board.

Randi Zuckerberg, sister to Mark, didn't make too much more than your average young I-banker at Facebook, with her pay topping out at $139,578 in 2010. (She left the company in the beginning of August 2011 but earned $89,536 that year.) 

An unnamed Zuckerberg - Someone in the Zuckerberg family got 2 million shares "in satisfaction of funds provided for [Facebook's] initial working capital. We're guessing that was a check for about $1,000 back in 2004.

Dustin Moskovitz, one of Zuckerberg's Harvard roommates, is the third largest stakeholder in Facebook, owning 7.6 percent of the company. (Accel is number two with 11.4 percent.) 

Sean Parker, as played by Justin Timberlake, got plenty of screen time in The Social Network but is mentioned exactly once in the filing as one of the stockholders who "agreed to vote all of their shares as directed by, and granted an irrevocable proxy to, Mr. Zuckerberg at his discretion on all matters to be voted upon by stockholders."

Eduardo Saverin is not listed in the S-1 filing. Anywhere.
