Tech firm to expand work for NHS

By the Editorial Team · Wednesday, September 23, 2026

Australian AI company Heidi, which supports NHS clinicians with automated clinical note-taking, raised $100 million in a Series C funding round valuing the firm at around $900 million. The investment will accelerate Heidi's expansion across the UK healthcare sector, enhance regulatory compliance, and double its London-based workforce while maintaining stringent data security standards.

An Australian artificial intelligence company used by doctors within the National Health Service (NHS) has secured $100 million in new funding to support its expansion in the United Kingdom. Heidi, founded in Melbourne in 2019 and initially known as Oscar, announced the successful close of its Series C funding round, which values the company at approximately $900 million.

Heidi specializes in AI-driven transcription and note generation services designed to help clinicians reduce administrative burdens by automating clinical note-taking after patient consultations. The company has also broadened its offerings to include access to medical research at the point of care, as well as audio conversion like voice-to-text services, aiming to enhance efficiency for healthcare professionals.

The company currently facilitates approximately 2.8 million patient interactions each week in 110 languages. This year, Heidi was selected to supply the NHS Midlands region, marking the largest clinical AI documentation procurement by the health service. The contract encompasses 15 acute and community trusts, several integrated care boards, and 1,239 general practitioner practices.

Beyond the NHS, Heidi’s services extend to private health and care providers such as Portman Dentex, a dentistry organization, and Sue Ryder, a palliative care charity.

To date, Heidi has raised a total of $436.6 million from a range of global investors. The recent funding round was led by Blackbird, an Australasian investment firm and existing stakeholder, with participation from Phoenix Court and others. Additionally, the company has secured a $240 million lending facility spearheaded by a fund tied to the US-based firm General Catalyst.

Raghav Sharma, Heidi’s European director, said the latest capital infusion will facilitate growth within the UK market and the NHS, including planned expansion from the firm’s London office. Currently, Heidi employs 67 staff members in the UK and aims to double that number. The investment will also be directed toward regulatory compliance and clinical safety development.

Sharma underscored the company’s commitment to data security, noting that all patient data is stored and encrypted within the UK. He emphasized the importance of robust security measures in addressing concerns held by clinicians, healthcare providers, and patients regarding the use of AI technology in clinical environments.
