Aemon

Aemon is an autonomous AI research-and-development engineer founded in 2025 by Ray Xu and Richard Zhou and backed by Y Combinator (Winter 2026 batch). Given an engineering problem and a measurable objective, Aemon reads state-of-the-art research, then generates, tests, and evolves thousands of candidate approaches at machine speed to discover optimal solutions that can exceed what human experts find. The team demonstrated the approach by setting a new world record on the NP-hard circle-packing optimization problem for under $10 of compute, beating a prior Google DeepMind result. Aemon is an early-stage, demo-first enterprise product headquartered in San Francisco; as of this profile it publishes no public developer API, SDKs, or documentation surface.

Aemon is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Machine-Learning, Research, and Optimization.

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/aemon: open an issue to ask a question, or submit a pull request to add artifacts.
