Distributed Spectrum
Distributed Spectrum builds AI-powered radio-frequency sensors and software that automatically detect, classify, and locate signals - drones, jammers, tactical radios, GPS spoofers - in real time. Founded by three Harvard engineers, the company packs commercial hardware and edge AI into sub-one-pound sensors that give soldiers and analysts persistent spectrum awareness without specialist RF expertise. It raised a $25M Series A in March 2025 and has fielded systems with US military branches and partners in Ukraine.
TERN
TERN is an Austin-based startup building IDPS (Independently Derived Positioning System), an AI-powered, software-only alternative to GPS. Instead of relying on satellite signals that can be jammed, spoofed, or blocked by tall buildings and tunnels, TERN's AI reads the sensors already inside vehicles and phones - accelerometers, gyroscopes, speedometers - and matches that motion against existing map data to figure out exactly where you are. Founded by AI engineers and former U.S. special operations personnel, TERN serves automakers, delivery fleets, emergency services, and defense customers who cannot afford to lose their location when the signal drops.
