GlassMapSaaS
Glassmap is a simple, beautiful way to show your friends where you are and what you are up to. Use it to coordinate meetings and hangouts, keep up with loved ones, and serendipitously discover who and what is around you. Available for iOS and Android phones. Glassmap was founded in 2011 by Geoffrey Woo, Jon Zhang, and Jonathan Chang, went through Y Combinator's Summer 2011 batch, and was acquired by Groupon in January 2013.
