Everyone knows Bono for his sunglasses, U2 fame, and activism, but not so much the fact that he's a cofounder of Elevation Partners, a private-equity firm that invests in new media and technology.

The firm is named after the U2 song “Elevation.” According to Bloomberg, Elevation Partners has invested $1.76 billion, with a 12% net internal rate of return. And you might recognize some names from its portfolio: Palm, Inc., Facebook, Forbes, and Yelp.

The Independent reported that the group brought in $1.4 billion from its investment in Facebook alone.
