Gartner predicts that by 2015, at least 60% of information workers will access content apps on mobile devices. Poised to capitalize on that trend is Aaron Levie, who launched cloud storage player Box from his dorm room at the University of Southern California in 2005. Levie’s mission today, as it was back then, is to make it easy and safe to share content from any device. The company -- backed by $300 million in venture funding -- has its sights set on enterprise customers, and last year, it more than tripled the number of Box deployments with 5,000+ seats. Next up: IPO.
