Heidi, the Melbourne-founded healthcare AI startup, has secured US$340 million in new funding to support its next stage of growth. Announced on September 22, 2026, the latest Heidi funding package combines a US$100 million Series C equity round with a separate US$240 million growth investment.
The company is expanding its ambitions beyond medical note-taking. Its goal is to help clinicians manage more of the administrative work surrounding patient care, while keeping medical judgement with healthcare professionals.
Heidi Funding: What the US$340 Million Package Includes
The financing has two distinct components:
| Funding component | Amount | Lead investor |
|---|---|---|
| Series C equity round | US$100 million | Blackbird |
| Growth investment | US$240 million | General Catalyst’s Customer Value Fund |
The equity round values Heidi at US$900 million. Existing investors Phoenix Court, Point72 Private Investments and Headline also participated. The full US$340 million package includes both forms of capital.
General Catalyst describes its Customer Value strategy as financing customer acquisition and sales and marketing activity. Its general model links returns to the customer value generated by that spending, allowing companies to preserve more of their own capital for areas such as product development and engineering.
The approach is designed to fund commercial expansion while preserving equity capital for longer-term product investment. General Catalyst describes this as a distinct financing model for businesses that already have an established customer acquisition process.
What Heidi’s Healthcare AI Platform Does
Heidi’s core product helps clinicians prepare documentation from consultations. Its Scribe workspace can combine a consultation transcript with relevant information, such as earlier notes, correspondence and uploaded results, to generate a draft note.
The platform also includes:
- Evidence: A clinical knowledge tool that provides responses with source citations.
- Tasks: A workspace for tracking actions identified during consultations or added manually.
- Templates: Customisable formats for different appointments and clinical settings.
- Heidi Remote: A device for hands-free audio capture.
These tools address several parts of a clinician’s working day. Their practical value depends on how well they fit existing routines and help staff complete work accurately. Generating a draft is one step; checking and using it remain part of the clinical workflow.
The demand for administrative support sits within a wider staffing challenge. The World Health Organization projects a shortage of 11 million health workers by 2030, concentrated mainly in low- and lower-middle-income countries. It also identifies training, recruitment, deployment and retention problems across countries at different income levels.
This context helps explain interest in tools that may free up clinical time. Software can support workforce capacity, while staffing, training and access to care still require investment.
Growing Usage Supports the Heidi Funding Story
Heidi reports that its platform supports around 2.8 million patient visits each week, with use across 190 countries and 110 languages. It also says it has supported more than 175 million visits in total.
These are company-reported usage figures. They indicate the scale of activity on the platform, rather than the number of paying healthcare organisations or individual clinicians.
For the business, a key task is translating broad usage into lasting relationships with healthcare providers. Continued adoption will depend on whether organisations find the software useful enough to incorporate into everyday work.
The latest Heidi funding follows a US$65 million Series B announced on October 6, 2025, led by Point72 Private Investments. That round valued the company at US$465 million and supported plans for product development and international expansion.
At the time, CEO and co-founder Dr Thomas Kelly, a former vascular surgical resident, described Heidi’s purpose as reducing administrative work so clinicians could concentrate on patients. The new financing builds on that direction.
Healthcare Providers Are Already Using Heidi
Adoption Across Metro South Health
In Australia, Metro South Health confirmed in September 2026 that it was implementing Heidi’s AI scribe across its health service following a 2025 trial.
The provider reported an average saving of 59 minutes a day for doctors. It also said 92% of clinicians reported spending less time on administration, while more than 70% of participating patients felt their clinician spent more time with them and listened more.
These findings reflect Metro South Health’s local trial and rollout experience. They give a concrete example of the operational benefits healthcare organisations are examining when deciding whether to adopt AI documentation tools.
Expansion Within NHS Services
In the UK, Walsall Healthcare NHS Trust announced in August 2026 that Heidi had been selected as the preferred ambient voice technology supplier for Walsall and The Royal Wolverhampton NHS trusts.
The decision followed an eight-month pilot involving emergency care and several outpatient specialties. The trust reported that average documentation time fell to under four minutes per patient.
The planned rollout begins in emergency departments and outpatient specialties, with expansion across all areas by 2028. The trust’s process requires generated notes to be reviewed, edited where necessary and approved before they enter a patient’s record.
Moving Beyond Documentation to Supervised AI Tasks
Heidi’s next product direction focuses on work that continues after a consultation note has been written. The company identifies preparation before visits, following up diagnostics and other operational tasks as areas it wants to address.
Its stated approach keeps medical judgement with clinicians while AI assists with clerical work. This shifts the product challenge towards completing useful tasks within established healthcare processes.
The Heidi funding announcement says part of the investment will support clinical evidence, quality management and regulatory submissions for these capabilities. It also states that the forthcoming capabilities will not be available in the UK and EU.
Clinical Review Remains Central to Adoption
Healthcare organisations must explain how the technology fits into care. Leeds and York Partnership NHS Foundation Trust tells patients that clinicians check and approve Heidi-generated notes before adding them to the health record. Clinicians remain responsible for the accuracy and content.
The trust also says patients can decline the tool or change their mind without affecting their care. Its information distinguishes documentation support from clinical decision-making, which remains with the care team.
For a company expanding across healthcare systems, these everyday practices matter alongside product development. Clear responsibilities, patient choice and reliable review procedures will influence whether new tools become trusted parts of clinical work.
