# Function Health Raises $450M for Its AI Preventive-Health Platform

> Function Health has closed $450 million in growth financing led by General Catalyst's Customer Value Fund, a large infusion for its AI-driven whole-body health platform. The company had previously raised a $298 million Series B in late 2025 at a $2.5 billion valuation, so this round marks a steep step up in capital. The product bundles more than 160 lab tests spanning cardiac, metabolic, and cellular health, then uses what it calls its MI Lab to spot trends and surface predictive insights over time. The idea is to shift medicine toward continuous, preventive monitoring rather than waiting for symptoms to appear. The raise reflects a broader wager that consumer preventive health, powered by frequent testing and AI-driven interpretation, is becoming a real category. The open questions are the familiar ones for this space: whether heavy testing meaningfully improves outcomes, and whether the model reaches beyond an affluent, health-obsessed early audience. A war chest this size buys Function a long runway to find out.
