About Greypoint Industries
Summary
Greypoint Industries builds LEGION, an autonomous drone swarm for military use that detects, geolocates, and tracks battlefield emitters by exploiting the enemy's own radio signals. The system targets previously hard-to-find threats, including jammers, command posts, and drone operators, giving warfighters precise, real-time location data on those targets. It shifts forces from reacting to incoming threats to proactively engaging the source.
Go-to-market
The direct customer is the military. The product addresses a defense procurement need for counter-drone and emitter-tracking capability at the unit level.

Building drone swarms that hunt drone operators
We build LEGION, a drone swarm that identifies, geolocates, and tracks every emitter on the battlefield using the enemy’s own radio signals. LEGION enables our warfighters to precisely track previously obscured targets like jammers, command posts, and drone operators so they can proactively respond to threats instead of reacting to them.
