Surtr Defense Systems, a startup aiming to unify the fragmented world of counter-UAS technology, has secured $4.8M in pre-seed funding from Y Combinator.
The YC P26 alum is developing ParallaxOS, an open operating system designed to connect disparate sensors, effectors, and software platforms into a single operational picture. Founded by former engineers from defense tech giants Anduril and Shield AI, Surtr aims to simplify integration and data sharing for defense operators, making existing systems work better together.
