Sheryl Sandberg

Sandberg’s job seems to center more and more on defending Facebook from its critics. In July, the Federal Trade Commission slapped the social network with a record $5 billion fine to settle claims that it mishandled users’ personal data; now some politicians are considering an antitrust probe. The negative attention hasn’t dented growth, at least so far: In 2018, revenue came in at $55.8 billion, up 37% year over year.
