With Tietoevry Banking-as-a-Service, banks and fintechs get something that sounds almost luxurious in financial IT - a modern core that hums in the background while teams focus on new products, not on patching old systems.

What Banking-as-a-Service offers

Tietoevry Banking-as-a-Service is a modular cloud platform that covers core areas like accounts, cards, payments and lending while handling regulatory and security requirements in the background. Banks plug in via APIs and can cherry-pick capabilities instead of buying a monolith.

The idea is simple but powerful: the heavy lifting runs in Tietoevry data centers or public clouds, while the bank designs the front-end and customer journeys. That separation of plumbing and experience is what many incumbents have been missing.

Focus on embedded finance and pooling

A visible use case is embedded finance, where non-banks such as retailers or platforms offer financial products on top of the BaaS stack. Tietoevry talks about enabling Banking-as-a-Service for partners who do not want to become full banks but still want regulated services in their apps.

At the same time, Tietoevry has been pushing concepts like ATM pooling and shared infrastructure, which fits neatly with the BaaS story: fewer duplicated systems, more shared rails, lower unit cost for cash and payments. For banks with thin margins, that is a very concrete lever.

How it feels in daily operations

For an IT team, working with Tietoevry Banking-as-a-Service should feel less like babysitting a fragile mainframe and more like managing a platform contract. Service level agreements, incident dashboards, version updates - much of it is standardized and predictable.

Developers, meanwhile, talk about building on documented APIs instead of deep-diving into COBOL code or undocumented batch jobs. That changes the mood in digital teams, because experiments and pilots become cheaper and less risky.

Strengths, but also dependencies

The strengths are clear: faster time-to-market for new products, reduced need for in-house core banking skills, and easier access to new rails like instant payments or digital wallets. For smaller banks, that can be the difference between staying relevant or quietly shrinking away.

But there is a flip side. Moving to Banking-as-a-Service creates a dependency on the provider's roadmap and pricing. Migrating off such a platform a few years later would be painful, so vendor selection and contract design become strategic boardroom topics.

Where Tietoevry wants to grow

Tietoevry positions its BaaS offering mainly in the Nordics and selected European markets where it already runs payment and core systems for banks. Expansion often starts with existing customers that want to carve out new digital brands or spin up greenfield propositions.

Analysts see BaaS as one of the growth pillars inside Tietoevry's Banking segment, alongside cards and payments software. The recurring revenues from long-running platform contracts can smooth earnings in a services-heavy portfolio.

Context for investors

Tietoevry has been gradually shifting from classic IT outsourcing to higher-margin software and platforms, and Banking-as-a-Service fits this transformation narrative neatly. It turns individual projects into long-term infrastructure relationships with banks and fintechs.
