Dennis Crowley (born June 19, 1976) is an American Internet entrepreneur best known for co-founding the popular social networking sites Dodgeball and Foursquare.


Crowley was born in Medway, Massachusetts to Mary Moraski Crowley and Dennis P. Crowley.[1] He grew up in a church-going close-knit family.[2] He graduated from Xaverian Brothers High School in Westwood, Massachusetts in 1994 and was featured in the front-cover story of Xaverian's seasonal magazine.[citation needed] He received a B.A. in 1998 from Syracuse University's S.I. Newhouse School of Public Communications and a M.P.S. master's degree in 2004 from New York University's Tisch School of the Arts Interactive Telecommunications Program (ITP).[3]


After graduating from Syracuse, Crowley worked as a researcher for Jupiter Communications. In 2000, he joined mobile app provider Vindigo as a product developer. In 2003, he worked on MTV's wireless product development side, and held stints at PacManhattan and ConQwest 2004.[4]

Crowley co-founded Dodgeball with fellow student Alex Rainert in 2003 while attending New York University.[5] Dodgeball was subsequently acquired by Google in 2005,[6] after which Crowley along with Naveen Selvadurai developed a second version of the original Dodgeball service called Foursquare in late 2008 and launched the service at SXSW in 2009.[7] Foursquare, offering location-based social networking services via mobile devices, had over 6 million users worldwide as of January 2011,[8] 10 million users as of June 2011[9] and 25 million users reportedly in August 2012.[10] It was reported in January 2016 that Crowley is no longer CEO of Foursquare and is now executive chairman.[11][12][13] He was replaced as CEO by Jeff Glueck.[14][15][16]
