Michael Greenhalgh
Founder, Health.AI · studied AI at Stanford · 40+ years in technology
michaelgreenhalgh.com ↗The client
A technologist and a clinic owner.
Michael Greenhalgh has spent more than 40 years in technology, studied NLP and AI at Stanford, and since 2007 has co-owned neurorehabilitation clinics that have helped thousands of patients across San Francisco, Sacramento, Oakland and San Diego.
He founded Health.AI around one idea: the gap between what medical science knows and what patients actually receive is the defining information problem of our time. Health.AI optimizes for accuracy, not engagement.
A vision that broad needs many products, for patients, clinics, practitioners and the public. Instead of hiring an agency or a large in-house team, Michael works with Generation AI: our engineers, led by our founder, and a fleet of AI agents.

- Direct conversations with the founder, with no layers of account managers.
- Fast cycles: working software every week, refined with real feedback.
