Dennis Crowley

CEO and Co-founder
Foursquare

The impact of the geo-location on mobile is undeniable, and Dennis Crowley has been at the forefront of the trend at foursquare and, before that, at Dodgeball, which was acquired by Google in 2005. But–since the plains are covered with the bodies of pioneers–will Crowley's check-in and mayoral empire prevail over incursions from competitors, most especially social networking giant Facebook? And, as it evolves, can he turn the start-up from a game into a real money- making business? Crowley holds a master's degree from New York University's Interactive Telecomm- unications Program and a bachelor's degree from the Newhouse School at Syracuse University.
