Groupon has acquired the Y Combinator-backed startup Glassmap, whose business products target deals to customers nearby.

The deal was announced by Glassmap on Friday, and terms were not disclosed.

“Groupon has revolutionized how people today use technology to interact with the real world, and that’s why we’re so excited to join them,” wrote co-founders Geoffrey Woo, Jon Zhang, and Jonathan Chang on Glassmap’s blog.

The acquisition signals that Groupon is continuing to build its original deals business. Most of its other recent investments, including the acquisition of a merchant relations manager late last month, have been to its increasingly important goods segment.

Glassmap’s location technology may allow Groupon to better target its deals with the consumers its merchants want to reach.

Glassmap described its business product this way: “Our location technology learns about your customers as individuals — their habits, preferences, and tastes. Ping each user with information relevant specifically to him or her. Remind someone to check out your latest deal when they’re in the area. Reward your most loyal visitors with exclusive deals and coupons.”

The Glassmap application, launched in 2012, will shut down on February 15.
