Quirin Privatbank Selects Tuum to Rebuild Core Banking Ahead of 2027 Pension Launch

Quirin Privatbank selected Tuum to build its core banking platform, targeting real-time payments and instant client onboarding, EIN Presswire reported on October 22, 2026. The bank will run Tuum's Accounts, Deposits, Payments and Loans modules, aiming to open new client accounts in minutes and settle payments instantly, including SEPA Instant.

What Quirin Will Run on Tuum

Under the agreement, Quirin Privatbank will run Tuum's Accounts, Deposits, Payments and Loans modules. The bank aims to open new client accounts in minutes, settle payments instantly including SEPA Instant, give its teams real-time access to transaction data, and produce regulatory reports considerably faster. Alongside the core migration, Quirin is targeting investment execution within the hour.

Tuum will sit at the center of a wider rebuild of Quirin's technology stack. Rather than running as a standalone system, it will be integrated with the bank's other platforms so that data moves between them as it is created. Tuum's cloud-native, API-first architecture is what allows that, and it leaves Quirin free to add or replace individual components later without disturbing anything else.

Sebastian Böttner, CIO of Quirin Privatbank, said: "We built our reputation on giving clients advice they can trust, and our technology has to keep pace with that. Our ambition is to run the most modern private bank in Germany, and that means real-time by default: payments that settle instantly, data we can see as it happens, accounts opened within minutes."

James Bushby, CRO of Tuum, said: "Germany has one of the most established private banking markets in Europe, with a lot of long-standing names competing for the same clients. The decisions being made now on whether they should modernize their core banking infrastructure will determine what these banks can sell for the next decade."

Quirin's Scale Behind the Tuum Build

According to akta.pro company records, Quirin Privatbank manages more than EUR 10.5 billion in assets for over 115,000 clients across 15 German cities. The same records list a 2026 product launch of quirion.Ai, an AI-powered wealth advisor using natural language processing and ChatGPT/OpenAI integration to provide conversational financial guidance to clients.

Quirin's Earlier 2026 Moves

On October 16, 2026, Quirin Privatbank and quirion partnered with Upvest to migrate their investment business to its API-based infrastructure, covering brokerage, custody, and settlement, The Paypers reported. The first product, Altersvorsorgedepot, will launch in early 2027, targeting 83% of Germans who do not invest.

On October 15, 2026, Handelsblatt reported that Quirin is investing up to €20 million in a new IT infrastructure, aiming to compete with neobrokers, particularly in the pension savings deposit area.

Altersvorsorgedepot Timing

Germany's Altersvorsorgedepot, the state-subsidized retirement investment account replacing the Riester pension, launches on January 1, 2027, and no certified products can be offered before that date. Quirin expects a substantial inflow of investment clients as the scheme opens, many of them investing for the first time.
