Less Manual Work. Better Capability.
Your team is stuck with clunky processes, training that doesn't stick, and tools that don't fit. RETSA Group fixes that. We're an Australian consultancy that builds practical AI tools, effective training, and streamlined workflows.
Whether you need better training, smoother processes, or AI tools that actually get used, we deliver practical solutions that fit how your team works.
Every solution is designed to fit how your team actually works, built for adoption rather than just delivery.
Programs built for retention and adoption, not just compliance checkboxes
Process improvements that give your team hours back each week
AI-powered solutions designed for adoption, not abandoned after launch
We started in training and learning design. Now we combine that foundation with workflow thinking and practical AI tools to solve real business problems.
RETSA Group is led by Marcus Rummler, an instructional designer and builder based in Penrith, NSW. With experience across insurance, utilities, and tech, Marcus brings a practical approach to every project.
No project managers or account handlers between you and the work. You talk directly with the person designing and building your solution.
