Building the AI Care Partner for Every Clinician

A month ago, we announced our $65 million USD Series B it’s a statement of belief from our investors. Belief in the mission we started 5 years ago. Belief that technology will help medicine restore the essential time and human connection that is the foundation of trust between clinicians and our patients.

Your response has been overwhelming and deeply affirming. It reminds us why we started Heidi and why we’re so committed to keep evolving.

As a doctor, I know firsthand what it feels like to practice medicine with and without Heidi. The difference is profound.

Starting Heidi I believed every clinician should practice with AI. Care would feel more human, not less. Patients would feel seen and supported. Every encounter would leave the system stronger.

Heidi exists to stand alongside clinicians, as an AI Care Partner - helping us deliver the care we dedicated our lives to.

As a company founded by clinicians, our purpose has always been to improve outcomes for both patients and practitioners. That commitment guides every decision we make. At Heidi, clinicians aren’t just users of our technology; they’re active partners in shaping it.

Our medical knowledge team is made up of clinicians turned engineers. They continuously evaluate model performance, review outputs and enforce robust clinical guardrails to ensure Heidi remains safe, accurate, and deeply human-centred.

From emergency departments in Canada to NHS Trusts in the UK and clinics across the US -Heidi is being embraced by the very people it was created to serve. Today, more than half of Australia’s GPs use Heidi, a reflection of the real, measurable impact we’re making on patient care - and the relief we’re bringing to clinicians.

To every clinician who’s welcomed Heidi into your daily practice — thank you. You’ve shown what’s possible when technology starts from empathy and you’ve helped us prove that AI can be deeply human.

With this latest funding, we’re accelerating our growth - investing in new languages, enhanced technology, and deeper clinical insights to make Heidi an even more capable partner.

But growth isn’t about scale for its own sake. It’s about earning the trust to sit beside every single clinician in the world.

We’re far from done.

The features that are coming will blow you away. We will transform care forever, together.

Heidi. By Your Side.
