Function Health closed a $298 million Series B led by Redpoint Ventures, valuing the company at $2.5 billion. The Austin‑based lab testing and imaging subscription startup offers consumers access to an expansive menu of diagnostic tests and imaging, tapping rising consumer demand for at‑home and direct‑to‑consumer health data. The financing underscores investor interest in consumer health platforms that combine diagnostics, data and care navigation. Function plans to scale lab capacity, expand the test menu and integrate imaging offerings, while preparing for reimbursement and regulatory complexities tied to diagnostic services sold directly to consumers.
