Quirin Privatbank picks Tuum for core banking overhaul

Quirin Privatbank has chosen Tuum as its new core banking platform as the German lender aims to speed up client onboarding, payments and investment execution. The bank is positioning the move ahead of Germany’s new Altersvorsorgedepot retirement investment account launch on Jan. 1, 2027.

Why it matters: - Quirin Privatbank is using a core system rewrite to push toward real-time banking operations. - The bank wants faster account opening, instant payments and quicker investment execution as Germany prepares for a new retirement investment market. - The move could help Quirin handle a likely wave of first-time investment clients when Altersvorsorgedepot opens.

What happened: - Quirin Privatbank selected Tuum as its new core banking platform. - The bank said the shift is intended to make Quirin the most modern private bank in Germany. - The agreement covers Tuum’s Accounts, Deposits, Payments and Loans modules. - Quirin expects to open new client accounts in minutes and settle payments instantly, including SEPA Instant. - The bank is also targeting investment execution within the hour.

The details: - Tuum will sit at the center of a wider rebuild of Quirin’s technology stack. - The platform will be integrated with Quirin’s other systems so data moves between them as it is created. - Tuum’s cloud-native, API-first architecture is designed to let Quirin add or replace individual components later without disrupting the rest of the stack. - Quirin expects real-time access to transaction data and faster regulatory reporting. - Sebastian Böttner, CIO of Quirin Privatbank, said the bank wants payments that settle instantly, data visible as it happens and accounts opened within minutes. - Böttner also said the Tuum setup should help Quirin bring new products to market faster and respond more quickly to client needs. - James Bushby, CRO at Tuum, said modernization decisions now will shape what German private banks can sell over the next decade. - Bushby said Quirin moved early and will be able to enhance or launch products without waiting for a vendor roadmap.

Between the lines: - Quirin is tying the technology upgrade to a specific market opening, not just a general modernization plan. - Germany’s Altersvorsorgedepot, which replaces the Riester pension, launches on Jan. 1, 2027, and certified products cannot be offered before that date. - Quirin expects substantial inflows from new investment clients when the scheme opens. - Reliability under higher volume and fast onboarding are likely to become key competitive tests for the bank. - The move also reflects a broader race among established private banks to modernize core infrastructure before the market shifts further.

What’s next: - Quirin will complete the core migration and integrate Tuum into its broader technology environment. - The bank is preparing for the Altersvorsorgedepot launch on Jan. 1, 2027. - Quirin expects to use the new setup to launch products faster and scale onboarding as demand rises. - The bank’s technology strategy leaves room to add or swap components later without a full system overhaul.

The bottom line: - Quirin is betting that a modular core banking stack will give it speed, flexibility and resilience as Germany’s retirement investing market opens.
