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.
