At 6 years old, Foursquare is among the established old guard that serves as inspiration for young entrepreneurs amid today's launch-and-burn startup ecosystem. The location app boasts a solid user base, impressive investors and, naturally, headquarters fit for a Silicon Alley success story. Located in New York's SoHo neighborhood, the space was chosen, designed and outfitted with employee collaboration in mind. "As soon as we saw our office in SoHo, we knew it was the perfect headquarters for Foursquare," said co-founder and CEO Dennis Crowley. "There are high ceilings with oversized windows, a massive skylight and views. We had a few priorities for the space: fostering collaborative communication, providing comfortable and functional work and meeting areas, and making sure the office still felt like Foursquare."
