(MoneyWatch) Facebook (FB) finally had its IPO, with insiders cashing out and selling 57 percent of the available shares. A number of people -- not just CEO Mark Zuckerberg -- and companies have seen their net worth rocket upward. In addition to the influence that money brings, these individuals and companies will have the pedigree in coming years of having been one of those involved with Facebook early on, meaning that they enter the Silicon Valley Pantheon, much the way as early backers and employees of such companies as Apple (AAPL), Microsoft (MSFT), and Google (GOOG) did. So, who are these people? Read on, as we present a combination of those at the top of Zuckerberg's management team and others who, whether from investments, being at the company early on, or smart negotiating, put away their own emu-sized nest eggs. We'll list what their holdings -- including stock they sold and stock they held -- is worth at the IPO price of $38.
