35 WOMEN UNDER 35 2016: Ruth Barnett, 32

As a former Sky News journalist covering social media, it’s fitting that Barnett was Snapchat’s first European communications hire. Prior to this, she was director of comms at start-up Second Home and SwiftKey’s VP of global comms. Her team there delivered one million users in a day for the launch of SwiftKey’s iOS app – through media coverage alone.
