93. Chris Cox

VP of Product, Facebook

Chris Cox is one of the Facebook employees whom Facebook CEO Mark Zuckerberg trusts the most. Cox first joined Facebook as an engineer in 2005 where he helped build the News Feed. In 2012, Cox played an instrumental role in Facebook's mobile efforts, requiring every employee to include a mobile mockup when pitching new products. He's since been put in charge of reinventing his original creation by turning the News Feed into an information-distribution hub for the entire Internet.
