Sonar was a free mobile application which showed the user how they are connected to other individuals in a room via publicly available social media profiles and location information from Foursquare, Twitter, and Facebook. [1] [2]
Sonar was founded by Ocean City, Maryland, native Brett Martin, [3] and was launched in 2011 at TechCrunch Disrupt New York. [1] [4] Sonar is the fourth business to come out of New York-based mobile incubator K2 Media Labs, with the previous three being Fingerprint, Tracks, and MarketSharing. [3]
Sonar has been offline as of September 2013, at which time Martin stated that he was no longer working on the project. [5]
