MELBOURNE, Australia– Heidi, a fast-growing healthcare AI company, has raised $65 million in a Series B funding round led by Point72 Private Investments, with participation from existing investors Blackbird, Headline, and Latitude, the growth fund of Phoenix Court. The new funding brings Heidi’s total capital raised to nearly $100 million and values the company at $465 million.
The Series B funding will accelerate Heidi’s mission to build an AI Care Partner designed to work alongside clinicians, automating time-consuming administrative tasks such as clinical documentation, evidence search, and patient follow-up. In just 18 months, Heidi’s technology has returned more than 18 million hours to frontline clinicians by streamlining their workflows.
“It is untenable that healthcare demand continues to rise while clinical time continues to shrink,” said Dr. Thomas Kelly, Heidi’s CEO and co-founder, and a former vascular surgical resident. “Building a sustainable healthcare system requires expanding clinical capacity without compromising clinician wellbeing or patient safety. That’s why I founded Heidi: to build an AI Care Partner that stands alongside clinicians, empowering them to deliver the care to which they have dedicated their lives.”
Heidi’s platform is currently used by tens of thousands of clinicians across more than 200 medical specialties, supporting over 73 million patient consultations to date and more than two million weekly consults in 110 languages across 116 countries.
The company plans to use the new funding to expand its workforce and grow its presence in the United States, United Kingdom, and Canada, while strengthening clinician-led adoption in France, Spain, Germany, Ireland, South Africa, Singapore, and Hong Kong.
Heidi’s AI platform is being deployed or tested across major healthcare systems worldwide. In the United Kingdom, the technology has been selected by Modality Partnership for the largest deployment of ambient AI in the UK and is being piloted at NHS Trusts across North West London and Lancashire–South Cumbria. In the United States, Heidi is partnering with Beth Israel Lahey Health, Massachusetts’s largest hospital network, and MaineGeneral Health, one of Maine’s leading hospital systems. In Canada, Heidi is the official AI partner of the Yukon Government. In Australia, it is working with Monash Health and Queensland Health Children’s Hospital and Health Service. In New Zealand, the Health Ministry has formally endorsed Heidi as one of only two AI providers approved to trial in the public system.
“We believe administrative burden is contributing to clinician burnout and capacity challenges across healthcare systems,” said Sri Chandrasekar, Managing Partner at Point72 Private Investments. “Heidi’s platform has the potential to meaningfully improve how clinicians manage their administrative workflows. We’re impressed by their adoption rates and excited to support their vision of expanding healthcare capacity while preserving the human touch in patient care.”
Heidi also announced two key executive appointments: Paul Williamson as Chief Revenue Officer and Dr. Simon Kos as Chief Medical Officer.
“During my career, I’ve chosen to work with companies that have transformed their industries — from Salesforce to Plaid,” said Williamson, previously Head of Revenue at Plaid. “Now, I’m proud to join Heidi’s mission to redefine healthcare in the age of AI.”
“With Heidi by their side, clinicians not only improve their experience of delivering care but also the patients’ experience of receiving it,” added Dr. Kos, formerly Chief Medical Officer at Microsoft. “Heidi’s bold vision extends beyond ambient voice technology to a future where every clinician can leverage AI to expand clinical capacity while preserving the human connection in care.”
