From Disrupt Battlefield Runner-Up To Veterans Of Proximity-Based Social, Sonar Tells All

My first-ever Disrupt was a year ago, almost exactly. I had just started working for TechCrunch and Disrupt NYC 2011 was my initiation, of sorts. I had heard of Disrupt before ? but witnessing the Battlefield first-hand, from the front row no less, is a totally different beast. Every uncertain moment or slip-up during a presentation left me worried, and each triumphant joke or wondrous moment made me clap as loud as the folks in the back. Looking back on that time, a handful of startups are still locked safely away in my memory, the most prominent of all being Sonar. That's because the second I heard the concept, I knew it would be a big deal. Considering a host of new apps on the market that do similar things, like Highlight and Crowded Room, I was right. But as Disrupt NYC 2012 (tickets here) draws nigh, I couldn't help but wonder what life has been like for Brett Martin and his social proximity company since launching on the main stage just a year ago. I set out on a mission to find out the answer, and Brett Martin was kind enough to oblige.
