The location-based startup in New York already brings in a small amount of advertising revenue - about $2 million in 2012, which is doubling about every quarter, according to a source familiar with the company’s financials. However, there may exist a much more lucrative stream of revenue deep in the guts of the company’s servers: monetizing data about venues and locations that it has collected from millions of check-ins throughout its roughly four-year lifetime. Foursquare already does this through a partnership with Gnip, which sells packaged data from social services like Twitter, but it may go beyond even that as the company is in talks with Yahoo to partner for the company’s location data - though the discussions are still fluid - according to two sources familiar with the matter. Foursquare was also reportedly in talks with Apple to serve up its location data for the iPhone’s Maps application, which was critically panned when compared with the robust data Google has available through its Maps application. Indeed, Foursquare’s data has become more valuable following Google’s $1 billion acquisition of Waze, according to a source familiar with the deal. Similar to Foursquare, Waze has a large community of users that essentially builds a database of intersections and streets along with traffic data, while Foursquare focuses on locations like venues and restaurants. Waze also uses data available through Foursquare’s platform. Get the full story at BuzzFeed
