The challenge
Breaking free from legacy
Having reached A$11bn portfolio under management, Bluestone was struggling with the existing legacy loan management system. They were unable to create and expand existing product set without extensive customisations to legacy code. In 2020, Bluestone decided to migrate their legacy to a more flexible, agile digital lending platform that can support their growth journey.
βThe immediate benefits of our new lending platform, powered by Mambu, are obvious in terms of improved efficiencies and better broker and borrower experiences.β
- Mark Jones, CEO of Bluestone

Mortgages, reimagined
The upgraded, digital lending platform includes a significant number of new features and improvements, including a suite of new loan origination and servicing capabilities, and takes Bluestone from a legacy system to an Amazon Web Services (AWS) hosted, cloud based platform, powered by Mambu.
The impact
Built for scale
The upgraded digital lending platform has resulted in 25 per cent growth for Bluestone for the quarter following the implementation, with this attributed to the combination of the use of the latest technology and Bluestoneβs personalised approach to each application.
