GroupMe is the best way to chat with everyone you know. It's absolutely free, whether you're talking to a group of friends, or texting with one person. Best of all, it works on nearly every phone, via push or SMS. With GroupMe, it's easy to reach anyone, anytime, anywhere.
GroupMe was founded by Jared Hecht and Steve Martocci in the Summer of 2010, inspired by a project conceived at the TechCrunch Disrupt Hackathon.
