Heidi Health raises $340M to deepen AI adoption across health systems
Heidi Health said it raised $340 million, combining a $100 million Series C led by Blackbird and $240 million from General Catalyst, to expand its AI Care Partner across health systems. The company also detailed Scribe, Evidence and new hardware as it reports adoption by Beth Israel Lahey Health and NHS England Midlands.
“From the day I started Heidi, the ambition was always bigger than writing doctor’s notes. I imagined that AI would sit alongside clinicians and complete real work under their supervision,” co-founder and Chief Executive Dr. Thomas Kelly said. Founded in Melbourne, Australia, Heidi is building what it calls an AI Care Partner designed to expand clinical care capacity for healthcare providers across every stage of care.
The funding and product expansion come amid strong adoption of AI in healthcare, especially in the United States. A survey led by the American Medical Association found that 81% of physicians surveyed in 2026 said they were using augmented artificial intelligence, more than double the rate in a poll sent out in 2023. “AI has quickly become part of everyday medical practice,” said AMA CEO and Executive Vice President John Whyte, MD, MPH. “Physicians see real promise in its ability to support clinical decisions and cut down on administrative burden.” Whyte cautioned that most physicians are generally supportive of AI in healthcare but are wary of patient use for tasks requiring clinical judgment. In many cases, doctors, nurses and clinical workers fear that AI might degrade the ability of human specialists to do their job appropriately if it takes the place of actual expertise.
Heidi appears to be working around those fears by designing its platform to augment, not replace, the foundations of trust and insight through a layer of administrative automation and research assistance. The platform’s core is Scribe, which listens ambiently to record patient history and symptoms, update records, provide multilingual support, organize text and prepare for likely questions such as coding suggestions and extra documents like handouts.
In addition to Scribe, Heidi released Evidence, which provides doctors, nurses and other professionals direct access to trusted medical research at the point of care. It automatically factors in active patient details, uploaded lab results and live conversation transcripts to generate summaries with in-line citations linked to original sources with risk scoring. The company said Evidence has answered more than 10 million queries since its March launch.
Heidi also shipped its first secure, wearable hardware device, Remote, built to work within clinical settings from surgery to community clinics, and Dictate, a voice-to-text feature. Kelly said the objective behind Heidi is to help ease the burden of clinicians and care providers while leading adoption across U.S. health systems.
Since the company’s Series B in October, Heidi has seen an enterprise activation rate of about 62% across major public and private health systems. In the United States, Beth Israel Lahey Health, one of the largest health systems in Massachusetts, uses Heidi. In the United Kingdom, Heidi was selected as the sole supplier for the National Health Service England Midlands, which the company described as the largest clinical AI procurement in NHS history.
