Swarm, a tool that helps retailers keep tabs on what their customers are doing by providing free, tracked WiFi, has closed a $1 million seed round from Nas, Brian Lee, FlightClub, and a number of other angel investors. The company told TechCrunch that it closed this seed round, which was raised over the last year, because it plans to raise a larger Series A round soon.
