At Tech Companies Like Facebook, the Founders Aren't the Only Ones Giving Big

Tech giants like Facebook have made multi-millionaires out of many more people than just their founders and CEOs. So while we do extensive coverage of people like Mark Zuckerberg, Sheryl Sandberg, Dustin Moskovitz, Chris Hughes and Sean Parker, we also dig down as much as we can to the second and third tiers, where relative unknowns are still capable of giving away millions of dollars. 

The latest example of this is Mike Schroepfer, Facebook's Chief Technology Officer.

When Facebook made its IPO, Schroepfer owned just over 2 million shares, or .11 percent of the company, which instantly made him worth nearly $100 million. Considering that Facebook's share price has nearly doubled since its IPO, and Schroepfer has been making well over $20 million a year, mostly in stock options, he's probably worth $200 million or more by now, though he has sold off the majority of his shares, and also donated a significant chunk of them to charity. 

According to SEC filings, Schroepfer donated 200,000 shares of Facebook stock to a charitable entity back in January, and just last week, donated another 40,000. At their current value, that's about $18 million worth of stock that Schroepfer has dedicated to charitable causes—a pretty significant chunk relative to his overall net worth.

So where is this money going? The trouble with SEC filings is that they don't typically list the recipients of charitable donations, just that the ownership of a stock was transferred to a charitable entity. So it's very difficult to say what causes Schoepfer supports.

If he doesn't personally disclose the information, finding out can be like searching for a needle in a haystack, combing over tax filings of nonprofits looking for a match.

One guess might be the Silicon Valley Community Foundation, which houses Mark Zuckerberg and Priscilla Chan's donor-advised fund, worth nearly $2 billion. Barring a response from Schroepfer, however, we may have to wait a year or more before we can even begin to find out.
