This year, Groupon has made a number of moves - including the launch of Gnome, Snap, Deal Builder, Pages, and Getaways - to prove that they are more than just a daily deals site for businesses and consumers. Today, they continued this identity shift with the acquisition of Swarm Mobile, a customer engagement platform and analytics dashboard for brick-and-mortars. Through WiFi, Bluetooth, and infrared technology, the San Francisco-based startup helps retail stores connect with and track customers while in-store. For example, with Swarm, stores can send timely, relevant promotions and information directly to a shopper's smartphone.
