We here at GroupMe HQ are big fans of Foursquare, and we’ve heard that a lot of our users love it as well. Today, we’re releasing a fun new feature that integrates the best of Foursquare into the GroupMe experience.

Try it out now: visit groupme.com/foursquare. After you connect your Foursquare account, we make it easy to start a group with the friends that are at or near your latest Foursquare checkin.

Imagine it with us: you’re at a concert and notice on Foursquare that a bunch of your friends are there too. But you don’t know where they are or how to get everyone together. You open up groupme.com/foursquare on your phone, check off all their names, and you’re instantly dropped into a GroupMe. With one text, everyone can plan where to go next.

We’re also open sourcing a lot of the code behind this new feature—check out boy wonder developer Pat Nakajima’s Ruby wrapper for the Foursquare API. It’s named John Mayer, of course.

Pat and our cofounder Steve Martocci will be presenting all this at tomorrow’s Foursquare Hack Day at General Assembly. You know, just a few months ago, GroupMe was born at a hack day here in New York, so contributing to this awesome hacker culture is really important to us. 

To recap: start a group with people nearby, check out John Mayer, and come say hi and make cool things at the Foursquare Hack Day. Happy Friday!
