Geo-based marketing is just getting started, and local businesses are feeling their way around how best to use service like Foursquare, Facebook Places, Gowalla, and even Twitter. It's hard enough if you have only one store. For chains and national retailers, managing Foursquare Specials across 400 stores is a nightmare. MomentFeed is trying to bring some order and analytics to this chaos with a location-based marketing dashboard aimed at businesses with more than one location. The LA-based startup just raised a $1.2 million seed round from DFJ Frontier, DFJ JAIC, Factual founder Gil Elbaz,and Rapleaf founder Auren Hoffman, and Walter Kortschak.
