Melbourne-based healthtech startup Heidi has closed a $65 million Series B round led by Point72 Private Investments, valuing the company at $465 million and bringing its total funding to nearly $100 million. Existing backers Blackbird, Headline, and Latitude also participated.
Heidi’s ambient AI “Care Partner” transcribes patient visits in more than 110 languages, auto-generates clinical notes, applies billing codes, and manages follow-up tasks. The platform has been adopted by over 60 per cent of NHS GPs, powering more than 340,000 patient consultations each week for major groups like One Care and the Modality Partnership.
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 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.”
With this new capital, Heidi plans to triple down on its UK, US, and Canadian expansions while sustaining growth in France, Spain, Germany, Ireland, South Africa, Singapore, and Hong Kong. The company will double its UK headcount to meet surging NHS demand.
Building an AI care partner
Founded by Dr Thomas Kelly, a former vascular surgical resident who experienced firsthand how paperwork erodes patient time; Waleed Mussa, an AI product veteran with deep experience in voice technology; and Yu Liu, who led engineering at scale-up voice-AI firms, Heidi claims to have returned more than 18 million hours to clinicians worldwide over the past 18 months. The platform now supports over 2 million patient consults per week across 116 countries.
Dr Thomas Kelly, the CEO and co-founder of Heidi and a 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.”
Heidi’s proprietary technology pillars include a real-time transcription engine optimised for clinical jargon, a HIPAA-grade cloud architecture ensuring data security, and a multilingual natural-language understanding model trained on millions of clinical dialogue snippets. These innovations set Heidi apart from competitors such as Suki, Nuance Dragon Medical, Robin Healthcare, and Notable Health, all of which offer ambient-voice or AI-scribe solutions but rely on legacy speech engines or fragmented integrations.
In the UK, Heidi has been chosen by Modality Partnership for the largest deployment of ambient AI in healthcare and by Cambridge University Hospitals NHS Foundation Trust.
Pilot programmes with Cambridge University Hospitals NHS Foundation Trust, the North West London Acute Provider Collaborative, and One LSC, serving over 4 million people, are being expanded into hospitals and specialist care settings.
