Icarus

Icarus is an aerospace and defense company building autonomous, solar-powered stratospheric aircraft for persistent surveillance and connectivity. Its APOLLO platform operates continuously above 60,000 feet, delivering rapid aerial intelligence, wide-area coverage across 1,000+ square miles, and always-on, low-latency (5-10ms) direct-to-device communications for weeks-long missions without ground infrastructure. Founded in 2023 and based in El Segundo, California, Icarus was part of Y Combinator's Fall 2025 batch. The company operates in the defense/aerospace hardware space and does not currently publish any public API, developer portal, SDK, or technical developer surface; this profile captures its identity for the API Evangelist network.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/icarus: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
