Foursquare
Foursquare, launched in 2009 by Dennis Crowley and Naveen Selvadurai, began as a quirky social check-in app and has since morphed into a major player in location-based technology. Known for its original gamified check-in system, Foursquare now focuses on providing data-driven insights and location intelligence to businesses. The company’s rebranding includes Foursquare City Guide, a recommendation app, and Foursquare for Business, offering analytics and marketing solutions. Despite facing competition from other location services, Foursquare remains relevant with its valuation hovering around $600 million, driving innovation in how we interact with the world around us.
