Heidi lands $340M to build 'AI care partner' for clinicians

Healthcare startup Heidi secured $340 million in funding to expand its AI-powered capabilities beyond clinical documentation. The Series C round, led by Blackbird, valued the company at $900 million and also attracted investments from existing backers Phoenix Court, Point72 Private Investments, and Headline. Blackbird's Customer Value Fund contributed $240 million to fuel Heidi's rapid growth.

The funding will enable Heidi to move from documentation to providing agentic capabilities that support clinicians in their work around patient visits. CEO Thomas Kelly emphasized that the company's goal is to act as an "AI Care Partner" to clinicians, freeing them to focus on patient care. In the past two years, Heidi's AI care partner has supported over 175 million patient visits, tripling clinical hours since September 2025.

Heidi's technologies include an AI scribe, clinical guidelines, Remote hardware for clinical work, voice-to-text Dictate, and clinical decision support tool Evidence. The company has deployed its solutions in 110 languages across 190 countries, including major U.S. health systems, the UK's NHS, and Australia's largest hospitals. Kelly stated that Heidi aims to increase healthcare capacity by automating administrative tasks and providing more time for patient care.
