Defense tech startups in Austin

Builds software-defined phased-array payloads, satellite buses and communications systems for defense, and is building its own satellite network.

Develops high-power microwave and directed energy systems, first for counter-drone defense, using gyrotron know-how from the founders' earlier microwave launch work.

Builds integrated RF detection, AI acoustic sensing and compact radar systems that detect and track drones and aircraft for security and counter-drone missions.

Trains military-specific AI models, Omega for command-level reasoning and Alpha for the tactical edge, to support operational decisions.

Builds Bullfrog, an autonomous robotic weapon station that aims machine guns such as the M240 to shoot down close-in drones.

Builds autonomous surface vessels from small attritable craft to larger ships, with autonomy software and a dedicated shipyard for the US Navy and allies.

Builds URZA, a vendor-agnostic orchestration platform that coordinates mixed fleets of autonomous systems across domains for the military and intelligence community.

Develops onboard AI agents that let operators command teams of drones and robots by voice over existing radios, even in disconnected environments.

Combines autonomous underwater vehicles with Absolute Ocean, a platform that fuses sonar and ocean data for near-real-time seabed intelligence.
