Airspace Defense (formerly Airspace Systems) is a Silicon Valley company that secures the low-altitude airspace where drones increasingly operate. Its patented Airspace Spatial platform fuses Remote ID, RF and electronic sensing, radar and AI analytics to detect, identify and track unauthorized drones and their operators at city scale. Founded in 2015 by a team from Apple, Google and Cisco, the company serves public safety agencies, national defense and major enterprises, and its autonomous Interceptor drone is held in the Smithsonian National Air and Space Museum.
SkyGrid builds high-assurance, third-party software services that safely fold autonomous aircraft, drones, and eVTOL air taxis into shared airspace. Born as a 2018 Boeing and SparkCognition joint venture and now a subsidiary of Wisk Aero, the Austin-based company delivers a real-time digital twin of the low-altitude sky - weather, obstacles, traffic, and vertiport status - plus automation and decision-support tools that route, synchronize, and deconflict flights at scale.
