Footfeed is a location-based mobile platform that allows brands to create their own check-in networks across multiple existing check-in services like Foursquare, Gowalla, and Facebook Places. It aggregates these networks into a single API platform. Brands can use Footfeed to engage customers by triggering messages on check-in, offering deals and rewards for locations, and sharing check-ins across social networks. Examples are provided of how Footfeed could be used by brands like Borders Books, Taco Bell, Coke Rewards, and for a Glee fan promotion. Licensing fees are based on either a monthly user fee or custom app development costs.
