AI healthcare startup Heidi raises $65M in series B funding at $465M valuation

Healthcare AI startup Heidi has secured $65 million in Series B funding, pushing its valuation to $465 million. The round was led by Point72 Private Investments, with continued backing from Blackbird, Headline, and Latitude, the growth fund of Phoenix Court. This brings Heidi’s total funding to nearly $100 million, fueling its push to reshape how clinicians manage their daily work.

Bloomberg confirmed the funding, reporting: “Heidi, a startup that uses artificial intelligence to automate administrative work for doctors, has raised $65 million in a new funding round led by billionaire Steve Cohen’s Point72 Private Investments.”

Heidi is building an AI Care Partner that works alongside clinicians to take over time-consuming administrative tasks like documentation, evidence search, and follow-up communications. For many healthcare professionals, these chores eat up almost as much time as patient care. Heidi’s platform has already returned more than 18 million hours to frontline clinicians in just 18 months, giving them back time to focus on patients instead of paperwork.

Dr. Thomas Kelly, Heidi’s CEO and co-founder and a former vascular surgical resident, framed the company’s mission against a backdrop of mounting pressure on global healthcare systems.

“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.”

Adoption has been striking. Tens of thousands of clinicians across more than 200 medical specialties use Heidi to reduce administrative load. Over the past year and a half, the platform has supported 73 million patient consults and now handles over two million consults every week in 110 languages across 116 countries.

With $65M in New Funding, Heidi Wants to Give Clinicians Their Time Back

In a blog post, Heidi said it plans to use the fresh capital infusion to grow its team and deepen its presence in key markets, including the United States, the  United Kingdom, and Canada, while continuing to build on grassroots adoption across France, Spain, Germany, Ireland, South Africa, Singapore, and Hong Kong.

Health systems in multiple countries are already integrating Heidi into their operations. In the UK, Heidi was selected by Modality Partnership for the country’s largest ambient AI deployment, and is being piloted with NHS Trusts in North West London and One LSC in Lancashire and South Cumbria, serving a combined population of more than 4 million people. In the United States, Beth Israel Lahey Health has signed on, and MaineGeneral has cited Heidi as a “transformation partner” across its network in Maine. In Canada, the Yukon Government has made Heidi its official choice. Australia’s Monash Health has adopted Heidi across 40 facilities serving 1.6 million people, and Queensland Health Children’s Hospital and Health Service is using it to support specialized pediatric care. In New Zealand, the Health Ministry has formally endorsed Heidi as one of two healthcare AI providers safe to trial in the public system.

Sri Chandrasekar, Managing Partner at Point72 Private Investments, sees Heidi as tackling a pain point that cuts across healthcare systems globally.

“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 the adoption rates they’ve demonstrated within health systems and are excited to support their vision of expanding healthcare capacity while preserving the human touch in patient care.”

Alongside the funding news, Heidi announced two key leadership hires. Paul Williamson, former Head of Revenue at Plaid, joins as Chief Revenue Officer, and Dr. Simon Kos, former Chief Medical Officer at Microsoft, steps in as Chief Medical Officer.

Paul Williamson explained his decision to join Heidi through the lens of his career trajectory.

“During my career, I’ve chosen to work with companies that have transformed their respective industries – from Salesforce in customer relationship management to Plaid in financial services. Today, I join Heidi’s mission to redefine healthcare in the age of AI.”

Dr. Simon Kos highlighted the human impact of the platform:

“With Heidi by their side, clinicians not only improve their experience of delivering care but the patients’ experience of receiving it. Heidi’s bold vision extends beyond the current promise of ambient voice technology and into a future where every clinician can leverage AI to expand their clinical capacity while protecting the human touch in healthcare.”

Founded in Melbourne, Australia, Heidi has grown from a local startup into a global healthcare AI partner used across emergency departments, general practice, and specialist clinics. The platform now processes more than two million consults weekly, adheres to strict privacy and security standards, including NHS, HIPAA, GDPR, and Australian Privacy Principles, and has secured SOC2 and ISO27001 certifications.

With this new capital and leadership, Heidi is positioning itself as a key player in reshaping how healthcare systems tackle administrative overload — a challenge that has long strained both clinicians and patients.
