Chief strategy officer, Snapchat
Estimated 2016 revenue: $367 million
At the Cannes ad festival last summer, Snapchat chief strategy officer Imran Khan could be spotted moseying down the Croisette by himself, seemingly just another ad-sales guy in jeans and a tucked-in collared shirt. Meanwhile, lesser industry notables ran around with entourages rivaling some rap stars. Never mind that Khan shepherds the hottest digital platform around. Choosing simplicity over pizzazz is part of what Snapchat CEO Evan Spiegel admires about his executive sidekick, who, eMarketer predicts, will turn the mobile app into a $1 billion business next year.
