Archangel Health
Founders
Archangel Health builds the infrastructure to post-train and evaluate medical AI, including RL environments inside real de-identified EHRs, physician-verified training data, and benchmarks that test clinical reasoning on hard cases. Frontier labs and medical AI companies use it today, and the company is moving toward post-training open-source models for health systems on their own data.
