# Function Health Secures $450M Growth Financing for Preventive Care Platform

> Function Health, a startup that sells AI driven preventive care, has raised $450 million in growth financing led by General Catalyst. The company runs a membership model that uses AI to analyze more than 160 biomarker tests along with medical imaging, aiming to flag disease early rather than treat it late. The round lands only eight months after a $298 million Series B, and the company says its annualized revenue is now approaching $1 billion. That is a striking pace for a health business, and a sign of how much appetite there is for consumer facing diagnostics that promise to catch problems before symptoms appear. The bet is that people will pay for continuous, data heavy health screening, and that AI can turn a flood of test results into something actionable. The open questions are the usual ones for the category, whether early detection at this scale genuinely improves outcomes or mostly surfaces findings that lead to still more tests.
