About Surtr Defense Systems
Surtr Defense Systems develops ParallaxOS, an open counter-UAS operating system for sensor fusion, command and human-authorised effector tasking. The software combines acoustic, visual, radar and other detections into correlated tracks, then presents operators with a shared operational picture and response controls.
Open interfaces let defence users connect existing sensors and effectors rather than replace them with one closed stack. The company has tested acoustic and visual FPV-drone tracking with military operators in Ukraine. Surtr raised a US$4.8 million seed round in July 2026 to expand engineering and field deployments.
