Tuum

Current accounts on Tuum run on their own ledger beside your legacy core. The new product line stays separate from the systems you rely on today.

Change one part of your stack, measure the results, and step back if it doesn’t work. That’s how careful lenders modernize without betting the business.

Start with one product on a modern core, running next to the system you already trust. Each step is small, visible, and reversible.

Current accounts and deposits bring customers back every day. Tuum gives you the accounts, payments, and real-time ledger to launch them.

Your savers already trust you with their money. Give them an everyday account to go with it, built on Tuum next to your existing systems.

Quirin Privatbank AG is building the most modern private bank in Germany, and they’ve chosen Tuum as the core to run it on. Back in 2006, Quirin became the first German private bank to drop commissions and go fee-only. Now they’re setting the pace on technology too: accounts opened in minutes, payments that settle instantly, investment execution inside the hour. And the timing is perfect. Germany’s Altersvorsorgedepot opens on January 1, 2027, and Quirin will be ready for the wave of first-time investors that comes with it. Welcome to Tuum, Quirin. We’re proud to be part of what you’re building. >>> Link to the full story in the comments.
