Surtr Defense Systems

Surtr Defense Systems is a Y Combinator-backed defense technology company building ParallaxOS, an open operating system for counter-UAS (counter-drone) command-and-control. Surtr positions itself outside the incumbent C2 tension by not competing with hardware partners on contracts and not monetizing partner data: hardware partners decide what data the platform sees, customers decide what data is kept, and every byte is visible to partners and customers in real time. ParallaxOS ingests any sensor (radar, RF, EO/IR, acoustic) over open defense-interoperability standards such as NATO SAPIENT, Link 16, Cursor on Target, and ATAK; tasks any compatible kinetic, EW, or directed-energy effector with human-in-the-loop authorization on every engagement; and performs multi-sensor fusion, autonomous track correlation, and AI threat classification at millisecond latency on the tactical edge. Customer data, integration code, and decisions remain the customer's, deployed on-prem or in GovCloud. Founded by Anshul Ahluwalia (CEO, ex-Shield AI) and Cameron Fiore (CTO, ex-Anduril, ex-Shield AI). Added to the API Evangelist network as a portfolio lead; no public developer API surface is published as of this enrichment pass.

Surtr Defense Systems is profiled on the APIs.io network. Tagged areas include Company, Defense, Defense Technology, Counter-UAS, and Command and Control.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/surtr-defense-systems: open an issue to ask a question, or submit a pull request to add artifacts.
