After arriving from rival Google in 2008, Facebook’s second-in-command has helped grow its 70 million user base into over 750 million active “friends” today, representing about 11% of the world’s population. COO Sandberg also helped monetize them. The dorm-room startup is prepping for a reported early-2012 IPO that could value the social media giant as high as $100 billion. The Harvard MBA served as chief of staff for the U.S. Treasury Department under President Bill Clinton, and managed Google’s online global sales and operations as a vice president. One of few prominent women in tech, Sandberg has been vocal about empowering women. “We still haven’t achieved the goal of real equality for women in the workplace and men in the home,” she wrote in an August op-ed. “We can–we must–do better.”
