Tuum: Powering Modular Core Banking for the Digital Age

At Money20/20 2025, Myles Bertrand, CEO of Tuum, discusses how banks have spent the last few years focusing on making the customer experience better and dealing with compliance issues like KYC and onboarding. However, when it comes to updating their core banking systems banks have hesitated and replacing these systems can be a huge challenge, which mostly leads to delays in changes that are really needed.

Instead a complete overhaul, Bertrand says the industry is now leaning towards a modular, step-by-step approach. Banks are opting to roll out specific new products or services like a digital card or a loan platform using modern infrastructure instead of trying to change everything at once. This way, they lower the risk and can quickly show value.

Tuum’s platform is built around five main modules: cards, payments, lending, transactional accounts, and general account services and many of their clients start with just one module to tackle a specific issue. Then, they expand from there what Bertrand calls a “land and expand” strategy.

He shared an example of a large traditional bank that had two outdated core systems and struggled to launch a new consumer lending product. Their innovation team teamed up with Tuum, and in just 12 months the large traditional bank managed to launch the new product using Tuum’s platform.

Bertrand’s comments show a bigger change in banking: moving from big revolutions to continuous evolution. Instead of taking big risks with core system overhauls, banks are choosing to innovate in smarter ways. It’s a more agile, customer-focused model, and Tuum is right in the thick of that change.
