Healthcare AI startup Heidi 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 investment values the company at $465 million, bringing its total funding to nearly $100 million.
The funds will accelerate Heidi’s goal of building an AI Care Partner designed to support clinicians by automating time-consuming administrative tasks such as clinical documentation, evidence searches, and patient follow-ups. According to research, clinicians currently spend almost as much time on administrative work as on direct patient care. In just 18 months, Heidi’s tools have saved over 18 million clinician hours by streamlining these processes.
Dr. Thomas Kelly, CEO and co-founder of Heidi and a former vascular surgery resident, said: “It is untenable that healthcare demand continues to rise while clinical time continues to shrink. 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 now supports tens of thousands of clinicians across 200 specialties, helping facilitate more than 73 million patient consults globally. The platform currently handles over two million consults weekly in 110 languages across 116 countries.
With the new investment, Heidi plans to expand its workforce and strengthen operations in the US, UK, and Canada, while deepening adoption in France, Spain, Germany, Ireland, South Africa, Singapore, and Hong Kong.

The company is working with several major healthcare systems worldwide, including the UK’s Modality Partnership — in what is described as the largest deployment of ambient AI in British healthcare — and pilot programs with NHS Trusts in London and Lancashire. In the US, Heidi is collaborating with Beth Israel Lahey Health in Massachusetts and MaineGeneral in Maine. It is also the official AI partner of the Yukon Government in Canada, and is working with Australia’s Monash Health and Queensland Health Children’s Hospital. New Zealand’s Health Ministry has endorsed Heidi as one of two AI providers approved for public health trials.
Sri Chandrasekar, Managing Partner at Point72 Private Investments, said: “We believe administrative burden is contributing to clinician burnout and capacity challenges across healthcare systems. Heidi’s platform has the potential to meaningfully improve how clinicians manage their administrative workflows. We’re impressed by their adoption rates and are excited to support their vision of expanding healthcare capacity while preserving the human touch in patient care.”
Heidi also announced new leadership appointments: Paul Williamson, former Head of Revenue at Plaid, joins as Chief Revenue Officer, and Dr. Simon Kos, former Chief Medical Officer at Microsoft, becomes Chief Medical Officer.
Williamson said: “During my career, I’ve worked with companies that have transformed their industries — from Salesforce to Plaid. Today, I join Heidi’s mission to redefine healthcare in the age of AI.”
Dr. Kos added: “With Heidi by their side, clinicians not only improve their experience of delivering care but also enhance the patient experience. Heidi’s vision extends beyond ambient voice technology to a future where every clinician can use AI to expand their capacity while protecting the human touch in healthcare.”
