Foursquare is a location technology platform dedicated to improving how people move through the real world. Their technology’s unparalleled sense of place and space has allowed them to help the world's leading brands and advertisers unlock valuable insights about their consumers and their businesses.
With their Pilgrim SDK, they use a whole array of dimensions and sensors to capture where people really are and confirm those signals with a self-refreshing map of the world that is rich in context necessary to understand a place, not just a location. They have a first-party panel who have consented to be always on in exchange for location utility.
