OpenEvidence closed a $735M Series D in January 2026 to push its physician-facing clinical search across more than 40% of US doctors, the largest deployment in the category. Ambience Healthcare reached $243M Series C as the leading ambient-scribe product against Suki AI's $70M and a still-private Heidi AI. Tempus and Recursion straddle this category and ai-drug-discovery, while Lunit and Harrison.ai dominate AI radiology in oncology and chest imaging respectively. Glass Health and K Health build clinical-decision-support layers on top of the EHR, and Color Health rebuilt cancer-care navigation around an AI copilot. FDA 510(k) clearances for AI-as-medical-device are now flowing at a record pace.

Key trends 2026
- Ambient scribes reach saturation pricing. Suki, Ambience, and Heidi compete at $200-400/clinician/mo, down from $600+ a year ago.
- OpenEvidence becomes the doctor-facing search default. $735M Series D funds outpaces any UpToDate-replacement attempt before it.
- FDA AI/ML 510(k) clearances accelerate. 2024-2026 device list growth tracks above 200/year, vs ~30/year pre-2020.

FAQ
Frequently asked
How is ai-medical different from ai-drug-discovery?
AI-medical covers point-of-care clinical tools — scribes, decision support, imaging, search (OpenEvidence, Ambience, Suki, Lunit). AI-drug-discovery covers preclinical R&D — molecular generation, target ID, protein folding (Recursion, Insilico, Chai). A few firms (Tempus, Recursion) operate in both.
Which AI medical startup has raised the most?
OpenEvidence leads at $735M total funding after its January 2026 Series D, focused on a clinical search product used by US physicians. Ambience Healthcare follows at $243M Series C for ambient documentation, then Suki AI at $70M.
Are these tools FDA-cleared?
It depends on intended use. Diagnostic imaging products (Lunit, Harrison.ai modules, NIRAMAI) carry FDA 510(k) or CE Mark clearance. Documentation and search tools (Ambience, Suki, OpenEvidence) typically operate as non-device clinical software, which has lighter regulatory requirements.
