GroupMe

GroupMe was acquired by Skype in August 2011.

Headquartered in New York, NY, GroupMe lets you effortlessly group text with the people in your life that are important to you. It's your real-life network, in your pocket. It's totally free and works on every phone.

GroupMe was founded by Jared Hecht and Steve Martocci in the Summer of 2010 and inspired by a project conceived at the TechCrunch Disrupt Hackathon.
