Function Health secured a $298 million Series B led by Redpoint, driving a $2.5 billion valuation for the consumer lab‑testing platform. The Austin startup provides subscriptions for hundreds of lab tests plus imaging, seeking to scale direct‑to‑consumer diagnostics and clinical integrations. Investors cited growing consumer demand for proactive testing and the potential to integrate diagnostics into longitudinal care. The funding will expand test menus, distribution, and presumably regulatory and lab infrastructure to support scale. The round underscores market interest in consumer‑facing diagnostics but raises execution questions on reimbursement, clinical utility, data privacy and the economics of wide test availability.
