Heidi, a fast-growing health care artificial intelligence (AI) company out of Melbourne, Australia, has secured $65 million in Series B funding to accelerate development of its AI Care Partner platform — a digital assistant designed to help clinicians manage administrative tasks and reclaim time for patient care.

The round was led by Point72 Private Investments, with participation from existing investors Blackbird, Headline and Latitude, the growth fund of Phoenix Court.

The raise values Heidi at $465 million, bringing total funding to nearly $100 million.

Automating the second shift

Heidi’s AI Care Partner automates documentation, evidence searches and follow-up communication, areas that often consume as much clinician time as patient care itself.

The company says its technology has already returned more than 18 million hours to frontline clinicians in 18 months.

“It is untenable that health care demand continues to rise while clinical time continues to shrink,” said Thomas Kelly, M.D., Heidi’s CEO and co-founder, and a former vascular surgical resident. “Building a sustainable health care 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 reports that tens of thousands of clinicians across more than 200 medical specialties are now using its system, supporting 73 million consults to date and two million consults weekly in 110 languages across 116 countries.

Expanding into major health care systems

With the new investment, Heidi plans to expand its workforce and physical presence in the U.S., U.K. and Canada, while deepening its footprint in Europe and Asia through clinician-led adoption.

The platform is already being deployed in major health systems.

• U.K.: Used by the Modality Partnership in the largest ambient AI deployment in the country, and in pilot programs with NHS Trusts serving millions across North West London and Lancashire.
• U.S.: Partnering with Beth Israel Lahey Health in Massachusetts and MaineGeneral Health, which called Heidi a “transformation partner.”
• Canada: Adopted by the Yukon Government for its public health system.
• Australia: Integrated with Monash Health and Queensland Health Children’s Hospital and Health Service.
• New Zealand: Formally endorsed by the Health Ministry as one of two AI vendors safe to trial in public settings.

Sri Chandrasekar, managing partner at Point72 Private Investments, said the firm was drawn to Heidi’s rapid adoption and focus on alleviating burnout.

“We believe administrative burden is contributing to clinician burnout and capacity challenges across health care systems,” he said. “Heidi’s platform has the potential to meaningfully improve how clinicians manage their administrative workflows.”

New leadership with tech and clinical pedigree

Heidi also announced two senior appointments: Paul Williamson as chief revenue officer and Simon Kos, M.D., as chief medical officer.

Williamson, formerly head of revenue at fintech company Plaid and an early executive at Salesforce, said he joined Heidi to help “redefine health care in the age of AI.”

“During my career, I’ve chosen to work with companies that have transformed their respective industries,” Williamson said. “From Salesforce in customer relationship management to Plaid in financial services.” He intends to do the same with Heidi.

Kos, previously chief medical officer at Microsoft, added that Heidi’s work extends beyond the current wave of “ambient AI” technologies.

“With Heidi by their side, clinicians not only improve their experience of delivering care but the patients’ experience of receiving it,” he said. “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 health care.”

Building trust and compliance

Heidi said its systems adhere to international privacy and security standards, including HIPAA, GDPR and Australian Privacy Principles, and have obtained SOC 2 and ISO 27001 certificates.

The company’s goal, Kelly said, is to build technology that feels like a true partner — not a replacement — for clinicians.
