He acquired health.ai and is building an AI-powered system that validates health information against the full body of medical evidence. This is his story, told by the team that builds alongside him.
Most health technology companies optimize for engagement. Health.AI optimizes for accuracy. Michael Greenhalgh's thesis is that the gap between what medical science knows and what patients actually receive is the defining information asymmetry of our era — and that AI, properly directed, can close it.
The internet promised to democratize medical knowledge. Instead, it created an ecosystem where misinformation spreads faster than peer-reviewed research, where supplement companies outspend universities on content marketing, and where a concerned parent searching for answers is more likely to find a sales funnel than a citation.
Health.AI exists to build the infrastructure that makes verified health information as accessible and reliable as GPS navigation. Not a chatbot. Not a symptom checker. A truth layer for all of healthcare.
