Backing Heidi and Inviting The Community Alongside Us
Video with no sound: A recorded video call with one of Heidi's founders, who talks in front of a window with city buildings behind him. For the first 38 seconds his words are on screen: "1 in 2 GPs in the UK use Heidi most weeks, 1 in 3 GPs in Canada, similar in Australia. If you think of how many visits they do, and then if they're saving a... and then if they are saving a few hours a day, on a national scale we increased GP capacity by a meaningful amount. It will definitely become standard of practice, like, in a few years. If you're seeing a doctor and they're not using some sort of AI system, it would be a bit unusual. It's always been a dream of mine find a way for clinicians to come on the journey, so we've had, like, ambassadors along the way, and others who've joined the team of course, but especially as the reach of Heidi's grown, it's been really hard for us to be able to give everyone a way to participate." Then a title card shows the word Archangel with its logo. After it no more captions show: the founder talks, at times alone and at times on a split screen with the interviewer, with the Archangel logo and word in the corner. It ends on the Archangel card again.
Welcome to Archangel's blog !
At Archangel, we have had the privilege of supporting Heidi Health since its earliest stages, when it was still ‘Oscer’. Looking back on the original concept deck, many of the core ideas were already present: ambient transcription, clinical documentation, support for diagnosis. What changed over time wasn’t the vision, but the clarity of execution that only emerges through deep iteration.
Today, Heidi has grown into one of the most widely adopted AI tools in clinical practice. It is used weekly by nearly half of all GPs in the UK, with similar penetration in Canada and Australia. More importantly, it is delivering real outcomes: reducing burnout, enabling clinicians to return to practice, and expanding healthcare system capacity.
There are three key reasons we continue to back this team:
- Founders deeply aligned with the end user: Heidi was not imagined from the outside in. It was built by clinicians, for clinicians, informed by first-hand experience and shaped by a clear understanding of daily pain points in healthcare delivery.
- A rigorous approach to market and timing: This is not a case of chasing generative AI hype. Heidi spent years building proprietary models, only to later embrace the wave of foundation models as a go-to-market accelerant. It’s a case study in timing meeting execution.
- Meaningful product-market fit: Heidi is not just being used. It is being championed by doctors who integrate it into their workflows, recommend it to colleagues, and advocate for it within their institutions. That level of adoption in healthcare is rare.
We are now offering our allocation in Heidi to members of its user base, those who have supported its growth, seen its impact firsthand, and wish to take part in its next chapter. It reflects a belief we hold strongly: that users, particularly in mission-driven categories like healthcare, deserve a seat at the table.
To the founders building in difficult markets: clarity and persistence still matter. To our fellow investors: adoption at this depth is worth studying.And to the Heidi community: we’re proud to extend the opportunity.
