Archangel Health

Archangel Health is building physician-graded clinical data infrastructure for medical AI. It sources, de-identifies and IP-clears clinical data to license to AI developers, and offers health systems a way to 'post-train' custom models on their own data inside their own IT infrastructure, keeping patient data HIPAA-compliant.

Medical AI is bottlenecked less by models than by high-quality, legally cleared training data. Archangel Health is going straight at that scarcity, with a network of credentialed physicians and over 20 distinct clinical data products.

The company was co-founded by Tej Patel and Aryaa Bhatia, both associated with UC Berkeley. Patel's background as a Truman Scholar with research in health economics and human-algorithm collaboration in clinical care informs the company's direction.

The founding team pairs a Berkeley research grounding in health economics and human-algorithm collaboration with a clear grasp of the sector's data-sourcing problem. They've assembled a network of credentialed physicians to grade the data — the hard, unglamorous part of the job.
