Entrepreneurs: Ben Yu and Deven Soni, founders of San Francisco-based Sprayable Energy.

Bonding at sea: Yu, who studied molecular and chemical biology at Harvard before joining Peter Thiel's fellowship, and Soni, a venture capitalist, met when they shared a cabin during an entrepreneurs-only expedition to Antarctica in 2011. The duo collaborated on a few projects before developing what they describe as the world's first caffeine-based topical energy spray.
