Toyin Ajayi is a board-certified family medicine physician and the co-founder and CEO of Cityblock Health, a New York-based company that builds neighborhood-rooted care for Medicaid and dually eligible patients - the people most health systems treat last. She co-founded the company out of Google's Sidewalk Labs in 2017, took the CEO seat in 2022, and has grown it into a roughly $6 billion business serving hundreds of thousands of members. Trained at Stanford, Cambridge, and King's College London, she practiced in safety-net hospitals and ran a clinic in Sierra Leone before deciding the system itself needed rebuilding. Her current obsession: making the most vulnerable patients the proving ground for AI in medicine.
