Mobile social network Loopt is turning on the revenue streams by going after the daily deal space. It already partnered with Groupon to show users nearby Groupon Now deals via notifications, but today it is launching its own twist on daily deals. Loopt is calling them U-Deals. Instead of going out and getting a large inventory of deals at local merchants, U-Deals lets users request their own deals. Once a deal hits a tipping point, then Loopt will contact the business and request the deal. This will require a sales force, but not one as big as a traditional daily deal provider. "One of the things we like about this is that it's neither self-serve nor a pure sales force model," says Loopt CEO Sam Altman. "In our beta testings, businesses respond well to a phone call like 'we have a check for $2000 and 100 new customers for you if you agree to this deal.'"
