FourSquare is leveraging its vast store of business locations for a new project — making tweet locations hyper-specific.

Twitter has announced that it’s working on making tweet locations more precise in a new partnership with Foursquare.

At first, the feature will only be available in select markets.

Right now, Twitter allows users to tag tweets with general locations like “Brooklyn, NY” or “SoMa, San Francisco,” but with Foursquare’s data, Twitter will be able to tag tweets to restaurants, stores, and potentially landmarks.

At the VentureBeat Mobile Summit in February, Foursquare chief revenue officer Steven Rosenblatt boasted the company had “triple digit revenue growth,” though he declined to name an actual growth number. However, he did say the Foursquare’s money comes from ads, data licensing, and local merchants subscriptions.

While Foursquare doesn’t have the most popular consumer apps, this new deal indicates it still has lots of valuable data.

The terms of the deal between Twitter and Foursquare have not yet been disclosed, but we’ve reached out to both companies for further information.
