Background
Surtr Defense Systems is a Y Combinator Spring 2026 company founded in 2026. YC lists Anshul Ahluwalia and Cameron Fiore as founders.
The company builds ParallaxOS, a hardware-agnostic operating system for drone defense.
The YC profile says the software ingests data from radar, RF detectors, cameras and acoustic arrays, then fuses those inputs into a single operational picture for counter-UAS teams.
Surtr is a software-layer C-UAS company. Its target problem is interoperability: base-defense buyers are accumulating sensors and effectors faster than they can make them work as one system.
