Deutsche Bank’s (NYSE:DB) Private Bank has taken a major step in its long-running technology overhaul by selecting Vault Core, the cloud-native core banking platform from UK fintech Thought Machine.
The choice is the first concrete move in a plan, outlined at the end of 2025, to shrink the division’s sprawling collection of core systems from 15 down to two modern, cloud-based platforms by the close of the current strategic cycle in 2028.
Vault Core will become the central engine for banking and lending products in Germany across both Personal Banking and Wealth Management.
The bank intends to replace a patchwork of older systems, cut operational complexity, and bring new products to market faster through a more client-focused model.
Development work has already begun. Testing is scheduled for later this year, after which products will move across in phases starting in 2027.
During the transition, legacy systems and the new platform will run side by side to protect service continuity.
Yiping Li, Chief Operating Officer of the Private Bank, described the selection as the moment strategy turns into delivery.
Simplifying the technology landscape, she said, should reduce complexity and create a more scalable base for growth while improving the experience for clients and staff.
Christian Rhino, the division’s Chief Information Officer, called the programme one of the most significant technology transformations under way in the Private Bank.
He highlighted Vault Core’s cloud-native design for greater resilience, scalability and flexibility, noting that separating product logic from the underlying infrastructure will let the bank design, adjust and launch products more efficiently and steadily reduce dependence on fragmented legacy platforms.
Thought Machine founder and CEO Paul Taylor said the partnership sets an example for how large international banks can modernise core infrastructure.
Replacing disjointed older systems with a contemporary architecture, he argued, gives the bank real-time capabilities that streamline operations, improve reliability and support better customer experiences at scale.
The agreement is structured as a ten-year partnership.
GFT Technologies has been appointed transformation and systems-integration partner.
The firm will draw on more than 25 years of work with Deutsche Bank plus its experience implementing Thought Machine platforms.
An integrated team spanning onshore, nearshore and offshore locations will handle the build and migration.
The move forms part of a broader effort to strengthen operating leverage in Personal Banking and provide a scalable foundation for continued expansion in Wealth Management.
Industry reports indicate the Private Bank is investing roughly €600 million in systems consolidation and expects annual run-rate savings of about €300 million by 2028.
Vault Core’s architecture, which isolates product configuration from the core ledger and infrastructure, is designed to support that goal by allowing faster product changes without large-scale recoding.
The first products slated for migration include everyday accounts such as call-money deposits. Success in Germany could later inform similar work in other markets, though the bank has so far confirmed only the domestic Personal Banking and Wealth Management scope for this first platform.
A second core platform has yet to be named.
The announcement marks a milestone rather than a finished transformation.
Careful parallel running, phased product moves and close coordination with GFT will determine whether the promised gains in speed, resilience and cost materialise. For now though, Deutsche Bank has chosen a clear technical direction and a long-term partner to begin dismantling one of the most complex core landscapes in European private banking.
