Heidi, the fast-growing healthcare AI company, today announced the closing of a $65 million Series B funding round, led by Point72 Private Investments with participation from continuing investors Blackbird, Headline, and Latitude, the growth fund of Phoenix Court. This round values Heidi at $465 million and brings total funding to nearly $100 million.

The Series B funding will accelerate Heidi’s mission to build an AI Care Partner that sits alongside clinicians, expanding their capacity by automating tasks such as clinical documentation, evidence search, and follow-up communications. Research shows clinicians spend nearly as much time on administration as on patient care. In just 18 months, Heidi has returned more than 18 million hours to frontline clinicians by streamlining critical administrative tasks.

Dr Thomas Kelly, the CEO and co-founder of Heidi and former vascular surgical 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.”

Tens of thousands of clinicians from over 200 medical specialties have turned to Heidi to ease administrative overload. Over the past 18 months, Heidi has supported 73 million patient consults and now supports over two million consults weekly in 110 languages across 116 countries.

As part of this Series B funding round, Heidi will continue to expand their headcount, office locations and local support in the USA, UK and Canadian markets and build on clinician-led adoption in France, Spain, Germany, Ireland, South Africa, Singapore and Hong Kong.

Primary care, hospitals and healthcare systems are exploring AI capabilities with Heidi, in:

the UK selected by Modality Partnership in the largest deployment of ambient AI in UK and Cambridge University Hospitals NHS Foundation Trust; in pilot programmes with NHS Trusts across the North West London Acute Provider Collaborative – a group of hospitals serving a local population of ~2.2 million and One LSC, the collective of the five NHS Trusts in Lancashire and South Cumbria, serving nearly 1.8 million people;
