Dennis Crowley is co-founder and executive chairman of Foursquare, a pioneer in the rise of the mobile, local, and social apps famous for pioneering the venue check-in concept. Today, it supports popular consumer apps and a large enterprise business around consumer geolocation data. The company has 150,000 developer partners and says it powers location experiences for more than 1 billion people globally.

Foursquare recently introduced Marsbot, an audio AR solution (i.e. a proactive walking assistant) that creates a reason to keep your hearables in all day when moving around a city or town. Marsbot harvests the nearly endless data from Foursquare's community and whispers nuggets of content to users as they go through specific locations.

Crowley started out in the early dotcom days as a research analyst and then became known for organizing large scale games that integrated technology with real-world settings. He then founded Dodgeball which was location-based social software for mobile devices and was acquired by Google in 2005. That led to some time at Google as a product manager before co-founding Foursquare in 2009.
