“From the day I started Heidi, the ambition was always bigger than writing doctor’s notes. I imagined that AI would sit alongside clinicians and complete real work under their supervision,” said Dr. Thomas Kelly, Co-founder and CEO of Heidi. “That’s the shift we’re now making: from documenting care to helping clinicians act on it. This round is about getting an AI Care Partner to every doctor in the world, and putting clinicians back at the center of care with their patients.”
The US$240 growth investment was led by General Catalyst’s Customer Value Fund (CVF). Commenting on the growth investment, Pranav Singhvi, Co-Founder and Partner at CVF, General Catalyst, said: We’re thrilled to partner on Heidi’s next phase of growth as they move from easing documentation to taking on more of the clinical work day.”
Founded in Melbourne, Australia, Heidi has raised US$436.6 million in funding to date, from global investors including Blackbird, General Catalyst, Phoenix Court (the home of LocalGlobe, Latitude and Solar funds), Point72 Private Investments, Headline, Possible Ventures, Glitch Capital and Archangel.
Heidi reported that its Annual Recurring Revenue (ARR) skyrocketed from US$1 million to US$50 million in just 24 months ending April 2026 as its platform has already scaled to support clinicians across 190 countries.
Heidi also shipped its first wearable device, Remote, built to work across settings, from surgery to community clinics, and Dictate, a voice-to-text feature.
