Hilary Mason
Chief Scientist, bitly
Age: 32

Mason may be one of the few females behind bitly, the popular URL shortening service that allows users to track the traffic and analytics data behind their links. But as its chief scientist, her smarts are essential in creating new products that keep the sharing site up to par with competitors. Mason also has a bleeding heart: She co-founded HackNY, a non-profit that connects student hackers with New York tech startups, in 2010.
