The Company

OpenEvidence builds an AI platform that helps clinicians find and synthesize medical evidence at the point of care.

It raised a $250 million Series D at a $12 billion valuation in January 2026, doubling the valuation reported at its preceding round.

Why It Matters

Clinical AI is a high-stakes category where product quality, evidence partnerships, and workflow adoption matter as much as model capability. OpenEvidence is a key private-market signal for trusted, vertical AI distribution.
