Earlier, Groupon had signed up many of the logical location-based services as distributors for its daily deals, and at the time, it was acknowledged that discussions were on with Foursquare. Now it’s official. Business Insider is a little too excited about this arrangement. Groupon’s real-time Groupon Now local deals are not widely available yet, and if Groupon ever gets its big data analysis act together, won’t be any more targeted than its emailed deals. It’s the real-time, hyperlocal geo-targeting that makes them different – geared more to impulse purchases, and thus useful for merchants as “inventory liquidation” (get fannies in seats, now) more than customer acquisition. And Foursquare still has only 10 million users. Don’t get me wrong – this is good for both companies. And Foursquare’s getting some revenue out of this deal, in contrast to some of its other “trial” partnerships.
