Medcast raises $5.4M to expand MedLuma, an Australian clinical knowledge platform for GPs

# What happened

Medcast, a medical education and training business founded in Bowral in 2013, has raised $5.4 million to expand its clinical knowledge platform, MedLuma. The round was led by Best Practice Software, a long‑standing Queensland medical software company.

# Why the raise matters

Best Practice's investment is aimed at bringing MedLuma into the clinical software GPs already use. Medcast and Best Practice already collaborate on clinical software and education, and the funding will support integrations with Best Practice's practice management systems.

# What MedLuma does now

MedLuma searches medical guidance and returns answers that link back to the original guideline or source material. The platform emphasizes three design choices:

• Sourcing: answers are grounded in Australian guidelines and medical publications.
• Traceability: outputs include citations that link to original materials so clinicians can verify sources.
• Local control: Australian health data is kept onshore and Medcast works with guideline publishers to obtain permission to use content.

Medcast describes MedLuma as combining technical checks with human review to produce results clinicians can trust.

# How the funds will be used

Medcast says the $5.4 million will be allocated to hiring in technology and clinical teams, product development, and integration work with clinical software platforms — specifically naming Best Practice's practice management systems.

# Who's behind Medcast

Medcast was founded by CEO Dr Stephen Barnett and chief product officer Justin Lewis in 2013. The company has provided clinical education and professional development to more than 100,000 registered healthcare professionals since its founding.

Best Practice CEO Craig Hodges is quoted as supporting the investment, noting confidence in the MedLuma team and platform and the opportunity to build a product tailored to Australian healthcare workflows.

# What this means for clinicians and practices

Clinicians using MedLuma can expect quicker access to guideline‑based answers with source citations, and an experience designed to sit inside or alongside clinical software they already use. The emphasis on Australian guidelines and onshore data storage is intended to address local regulatory and trust concerns that influence adoption in primary care.

# Immediate next steps

Medcast will scale headcount in engineering and clinical roles and focus product work on deeper integrations with practice management systems, starting with Best Practice, to make MedLuma accessible in the tools clinicians already use.

# Bottom line
