A patient walks in, describes something complex and human — pain that they live with, anxiety that they carry, a child's symptom that a parent can't quite articulate. The clinician listens carefully, asks the right questions, builds a picture with precise follow-up. The clinician wants to be present, but they can’t stop looking at their monitor as they’re typing up notes, populating electronic health records, drafting referral letters, coding for billing.

It is estimated that clinicians spend over two hours daily on after-hours documentation. The industry has a name for it: pyjama time. A cute phrase that tells you Doctors are finishing their paperwork in bed.

Burnout among physicians is on the rise, with the vast majority reporting that administrative burden is a primary driver. Health systems lose clinicians to early retirement, career changes, and sheer exhaustion.

For decades, clinicians relied on dictation software that turned speech into text but still required them to organise, structure, and edit their notes, so the administrative burden barely shifted.

Enter Heidi Health.

Heidi is an ambient AI medical scribe that listens during consultations and generates accurate, structured clinical notes — automating the documentation that consumes so much of a clinician's day. Describing Heidi as just a scribe understates what the team is building.

The product is a clinician workspace: it captures the consultation, generates multiple outputs from a single session (clinical notes, referral letters, task lists), recalls patient history across encounters, and gives clinicians a command layer to interact with their documentation naturally.

What makes Heidi distinctive is who it serves and how it reaches them. Where most competitors have focused narrowly on physicians in large hospital systems, Heidi works across general practitioners, psychiatrists, allied health professionals, veterinarians, nurses, dietitians, and more. Its template engine, built and refined by clinicians themselves, adapts to specialities, workflows, and geographies in a way that top-down enterprise tools simply cannot.

Heidi was founded in 2019 by Dr. Thomas Kelly, Waleed Mussa, and Yu Liu. Tom is a former surgical resident who has spent the better part of a decade building software for healthcare, including a previous business that reached meaningful scale. Over twenty per cent of Heidi's team have clinical backgrounds, which shows up in the product's intuitive design and its deep understanding of the workflows that matter.

The Heidi founding team have the traits we look for most in founders: radical self-belief in their vision, intellectual curiosity that drives them to seek feedback and iterate, and resilience forged through multiple pivots before finding the right product at the right time.

Heidi's Series B is led by Point72 Ventures, with participation from Blackbird and existing investors including LocalGlobe, Headline Ventures, and Saniel.

Traditional enterprise sales cycles in healthcare are notoriously slow. Procurement processes stretch across months, bake-offs involve dozens of physicians, and deep integration testing creates friction at every stage.

Heidi took a fundamentally different product led approach. Its freemium model allows any clinician to start using the product immediately, with no onboarding required and no IT department involved. A single doctor tries Heidi in their clinic, sees the time savings, and tells a colleague. That colleague tells their department. The department tells their health system. By the time an enterprise conversation begins, Heidi already has passionate internal champions and real usage data to point to.

This pattern has played out repeatedly. In one large health system, a paediatric surgeon who used Heidi in private practice introduced it internally, sparking adoption across nearly thirty departments within sixty days. In another, clinicians refused to trial alternative vendors after experiencing Heidi, choosing to self-fund access while waiting for institutional approval. These are not stories you hear about most enterprise software.

The magic of this motion is that it was organic. Heidi's intuitive interface, instant onboarding, and distinctive brand identity resonate with clinicians in a way that creates genuine word-of-mouth virality within clinical networks. The result is a go-to-market engine that is extraordinarily efficient — Heidi has spent far less than competitors on paid distribution while growing at a remarkable pace.

Healthcare is one of the hardest sectors to build software for. The workflows are labyrinthine, the terminology is specialised and unforgiving, every decision carries real clinical stakes, and the regulatory landscape shifts across every jurisdiction.

Products in this space demand an unusual level of trust from their users; clinicians will not adopt tools built by teams that don't understand their world from the inside. That's what makes Heidi's founding team so compelling. Dr Thomas Kelly, the CEO, trained as a surgical resident before moving into healthcare software. He's spent roughly a decade building products at the intersection of medicine and technology, including a previous venture that reached meaningful scale.

Tom is joined by co-founders Waleed Mussa and Yu Liu, and together the team has navigated one of the more impressive pivot sequences we've seen. Heidi started life in 2019 as Oscer, an education platform training medical students through simulated case studies. When the complexity of that vision created too much onboarding friction, the team had the self-awareness to strip back and refocus. The result was Heidi's ambient scribe, launched in early 2024, which found explosive product-market fit almost immediately.

What stands out about the founding team is a combination of traits we weight heavily: radical self-belief in the vision, intellectual curiosity that drives them to seek out feedback and challenge their own assumptions, and the resilience to pivot repeatedly without losing momentum or conviction.

They move with rare operational intensity that shows up in the pace of product iteration at Heidi being remarkably fast for a company operating in a regulated, high-trust category.

In a market where core ambient scribing functionality is rapidly becoming table stakes, Heidi's differentiation lies in how deeply it serves the clinician. The template community is central to this. Clinicians build, share, and customise documentation templates across specialities — and adoption of this ecosystem has been a critical driver of engagement. Influential clinicians have become effectively product designers, creating templates that increase the product value for everyone.

This creates a flywheel. More users contribute more templates, which increases the value of the platform for all users, which drives further adoption. The feedback loops enable faster product iteration than competitors who rely on top-down design processes. And the cross-specialty coverage, from general practice and psychiatry to aged care, rehabilitation, and veterinary medicine, reaches clinician populations that enterprise incumbents have largely ignored.

Anecdotally, market references are indicating that Heidi has surpassed competitors in accuracy over the course of this year, a testament to the compounding data advantage of large-scale usage data and rapid iteration cycles.

The US ambient scribe market is intensely competitive. Incumbents like Abridge, Nuance DAX, and Suki have deep integrations with electronic health record systems, established relationships with large hospital networks, and hundreds of millions in capital. Winning head-to-head in the top tier of US health systems is difficult for any challenger.

The vast majority of global clinical care takes place outside of tightly integrated health systems. Small practices, aged care facilities, allied health providers, public health systems across the United Kingdom, Europe, Canada, Australia, and beyond — these environments often lack the IT infrastructure or procurement processes that integration-heavy vendors require. They represent an enormous portion of the addressable market, and they are structurally underserved.

Heidi's frictionless product-led growth motion, regulatory compliance across markets, and flexible template ecosystem make it uniquely suited to these fragmented international markets. The company has already established strong momentum in the United Kingdom's National Health Service, across Australian and New Zealand health systems, and is focused on European expansion. Heidi has a credible path to becoming the de facto ambient scribe platform outside the United States.

There are over eighty vendors globally pursuing variations of ambient documentation and clinical workflow automation. The category is competitive, particularly in the US, and product differentiation is narrowing as nearly every company expands into the same roadmap: coding automation, pre-charting, clinical agents, task execution.

We believe Heidi can thrive in this environment for several reasons. Its product-led growth engine creates distribution leverage that is genuinely difficult to replicate. Its template community and clinician feedback loops enable faster localisation and specialisation than top-down competitors can achieve. And its global-first positioning means it is building share in markets where incumbents are not focused.

Even in the US, Heidi has demonstrated the ability to displace better-funded, more deeply integrated competitors by winning clinicians over with superior usability and speed of deployment. Competition is real, but 'Heidi's path does not depend on winning every bake-off — it depends on being the platform clinicians choose for themselves.

What drew us to Heidi was a rare combination: a product that clinicians genuinely love, a go-to-market engine that turns that love into scalable distribution, and a founding team with the clinical depth and operational intensity to execute against a massive global opportunity.

The ambient AI scribe market is at an inflection point. Adoption is accelerating rapidly, and the category is evolving from simple documentation into the interface layer through which clinicians interact with their entire workflow.

But we believe the scribe is just a beachhead into the medical market. Heidi always pitched a vision beyond the medical scribe, and since we’ve invested, the team has continued their rapid product execution and launched the Evidence, Comms and a hardware product, Remote.

We are backing Tom, Waleed, Yu, and the Heidi team because they have earned the trust of tens of thousands of clinicians worldwide, because they move with extraordinary speed, and because they are building something that makes healthcare professionals' lives better.
