Sonar is a mobile application that uncovers the hidden connections you share with people nearby. We bottle the 1000s of connections that you miss every day- friends, friends of friends, fellow alumni, likeminded strangers- and put them in the palm of your hand. In real time. The best part of sonar is that it works even if no one else is using it. Every time you open the app, sonar scours the web for people nearby, synthesizes their publically available profiles, and intelligently sorts them by their relevance to you. Networking is about to get a lot more efficient.
