Surtr Defense Systems

The open operating system for counter-UAS

Y CombinatorSpring 2026ActiveIndustrialsDefense

What they do

Problem

Organizations defending airspace struggle to integrate disparate counter-UAS sensors into a unified, actionable view for detecting, classifying, and responding to drone threats.

Solution

ParallaxOS is an open counter-UAS operating system that fuses data from multiple sensor types into one interface with AI-driven threat classification and engagement recommendations while keeping a human in the loop.

Who it's for

Defense and security operators (military, government, and critical infrastructure security teams) running counter-UAS systems.
