Surtr Defense Systems
The open operating system for counter-UAS
We are building ParallaxOS, an open operating system that fuses sensor data from any radar, RF detector, camera, or acoustic array into a single unified view. It uses AI to classify drone threats and recommend engagement options, all through one interface that supports any hardware and keeps a human in the loop.
We live and work in San Francisco, CA, and plan to base the company here after YC.
San Francisco is where we both live and have access to our technical and defense industry networks. It's the right place to build and scale Surtr.
