# Function Health secures $450M growth funding for preventive care AI

> Function Health has closed a $450 million growth round led by General Catalyst, while holding its valuation at $2.5 billion. The financing comes just eight months after a $298 million Series B, a fast follow-on that signals strong investor conviction in the company's model. Function sells consumers a subscription for comprehensive lab testing and AI-driven interpretation, aiming to turn scattered biomarkers into personalized, preventive health guidance. The pitch taps a growing appetite for people to measure and manage their own health data rather than wait for something to go wrong. The new capital is paired with acquisitions that fill out the offering. Function has picked up Getlabs, which handles mobile blood draws, and SuppCo, a supplement tracker, moves that push it toward an end-to-end loop of testing, insight, and action. Whether preventive testing at this scale meaningfully improves outcomes is still an open question, but investors are clearly betting on demand.
