Foursquare

Foursquare is a geospatial technology company that turns the physical world into structured, privacy-minded location data. Once known for the check-in app that helped popularize mobile location sharing, the company reinvented itself as an independent location-intelligence platform. Its products - Places, Movement SDK, Studio, and the Graph - supply a database of 120+ million points of interest and movement signals that power maps, marketing, analytics, and app features for companies including Apple, Uber, Snapchat, and Spotify.
