Having operated on a legacy core system for over 20 years, Leeds Building Society is moving onto Mambu to strategically transform its technology stack.

Mambu, a cloud banking platform, and Leeds Building Society, the fifth largest building society in the UK, have entered a strategic partnership to help Leeds modernise its core banking system.

By using Mambu, underpinned by Amazon Web Services (AWS), Leeds Building Society will have an enhanced capability to build innovative mortgage and savings products and increased flexibility to serve the needs of its 900,000 members, through the use of modern cloud technology.

Rob Howse, COO at Leeds Building Society: “At Leeds Building Society, we  knew we needed to address the sustainability and flexibility of our existing banking systems if we were to deliver on our purpose of putting home ownership within reach of more people, generation after generation."

"We are thrilled to select Mambu as our core banking platform partner. Mambu stood out as a true pioneer, providing a solution that brings the best composable architecture and cloud technology, coupled with a clear desire to innovate and deliver fantastic functionality.”

This partnership will allow us to spend less time managing our legacy systems and more time focusing on improving our members’ experiences, which is our main priority.

Leeds Building Society joins a growing number of fintechs, lenders and regulated banks in the UK that run on Mambu, including Mutual Vision, Aldermore Bank, Ashman, Tide, Tandem Bank, and Allica Bank.

Fernando Zandona, CEO at Mambu: “We are excited to be working with Leeds Building Society, helping the team transform its organisation to meet the demands of members. The company's commitment to innovation and its focus on delivering exceptional products and services is something that we greatly admire.

Running on Mambu, Leeds Building Society can accelerate how it responds to new member expectations through technology and stay ahead in a dynamic market. This is something that we are very familiar with at Mambu, as we are currently supporting 20 fully regulated banks in the UK on their complex transformation and migration programmes. We look forward to supporting Leeds in the next phase of its journey.”
