Medcast Raises $3.56M to Scale Clinical AI
Medcast raised $3.56M led by Best Practice Software to expand its MedLuma clinical AI platform for Australian GPs.

The big picture: Medcast, an Australian medical edtech company, has raised $5.4 million (AUD) to advance its clinical AI platform, MedLuma. The funding round was led by veteran Queensland medical software business Best Practice Software.
Why it matters:
- Clinical Trust: MedLuma addresses the critical need for trustworthy AI in healthcare by grounding its answers in Australian guidelines and medical sources, complete with citations and human review.
- Efficiency for GPs: The platform aims to significantly reduce the time doctors spend searching for clinical information, allowing them to focus more on patient care.
- Strategic Integration: The investment from Best Practice Software, a major player in practice management systems, signals a move towards integrating MedLuma directly into existing clinical workflows.
How it works:
- Evidence-Based AI: MedLuma provides AI-powered search results for clinical questions, drawing exclusively from Australian guidelines and medical sources.
- Transparency and Verification: Each answer includes citations linking to original material, and the platform combines technical checks with human review to ensure accuracy and reliability.
- Data Security: Medcast emphasizes keeping Australian health data onshore and collaborates with guideline publishers to secure content permissions, building trust among clinicians.
The catch: While MedLuma’s focus on Australian guidelines and data residency builds trust, it also limits its immediate market reach. The challenge of integrating new AI tools into established clinical software ecosystems, even with a strategic investor, can be complex and slow, potentially hindering rapid adoption beyond early adopters.
