Heidi Health Raises $100M Series C+ Led by Blackbird to Expand AI Care Partner

Heidi Health Secures $100M Series C+ Round

Melbourne-based Heidi Health has raised $100 million USD in a Series C+ funding round led by Blackbird. The round, dated September 22, 2026, also included participation from Headline, Point72 Private Investments, and Phoenix Court's growth fund Latitude. This latest injection of capital brings Heidi's total funding to $96.6 million USD, according to the company.

What Heidi Health Does

Heidi is building an AI Care Partner designed to expand clinical capacity by supporting every stage of care delivery. The company's platform goes beyond its original AI scribe offering. It has introduced Evidence, a feature that gives clinicians access to trusted medical research at the point of care, enabling healthcare teams to coordinate patient communications more effectively.

The company reports that its technology supports more than 2.7 million patient interactions each week, operating in 110 languages across 190 countries. This global reach underscores the platform's scalability and its potential to address clinician shortages and administrative burdens in diverse healthcare systems.

Market Position and Compliance

Heidi aligns with leading international healthcare and privacy frameworks, including NHS requirements, GDPR, HIPAA, and the Australian Privacy Principles. The company maintains enterprise-grade security certifications such as ISO 27001, SOC 2 Type II, Cyber Essentials Plus, and ISO 42001. These credentials are critical for healthcare organizations evaluating AI vendors, as they demonstrate a commitment to data protection and regulatory compliance.

Investor Perspective

The Series C+ round was led by Blackbird, a prominent Australian venture capital firm. The participation of Headline, Point72 Private Investments, and Phoenix Court's Latitude fund signals broad international interest in Heidi's approach to AI-driven clinical support. The funding will likely accelerate product development, market expansion, and further integration of AI into care delivery workflows.

Implications for the Healthcare AI Market

Heidi's raise comes amid growing demand for AI solutions that can alleviate pressure on healthcare systems worldwide. By combining an AI scribe with evidence-based research access and patient communication tools, Heidi positions itself as a comprehensive care partner rather than a point solution. The company's ability to operate across 190 countries and support 110 languages suggests a robust technical infrastructure and localization strategy.

For investors and acquirers, Heidi represents a scaled AI healthcare platform with strong compliance credentials and a large, addressable market. The Series C+ funding provides capital to deepen its moat and expand its footprint, making it a notable player in the clinical AI space.
