Raiffeisen Bank International (RBI) is one of Central and Eastern Europe’s leading banking groups, serving 18 million customers through a network of subsidiary banks in 11 countries. With a mission to become the region’s most recommended financial services provider, RBI has consistently invested in digital transformation to improve speed, cost-efficiency, and increase customer experience.
RBI has deployed Temenos Core Banking in Kosovo, Slovakia, Bosnia and Herzegovina, and in its branches in Poland and China. The group’s relationship with Temenos began in 1999 and continues to evolve with a clear focus on modernization and innovation
Strengthening across borders
Like many European institutions, the group faces the challenge to deliver consistent, seamless digital services, both through branches and online channels. This requires a modern IT landscape that supports agility, shorter time-to-market, scale, and cost efficiency.
Temenos Core Banking plays an important role in RBI’s transformation. Different group entities run various versions of Temenos Core, with the most recent deployment in Bosnia and Herzegovina. RBI is now evaluating upgrades modernization and further deployments, including a broader future shift toward cloud-native banking. This is now a key milestone on its technology roadmap.
Temenos is a reliable partner in one of the most critical areas of our IT landscape. Our joint planning through vendor bodies with Temenos on operational and strategic level and roadmap alignment has allowed us to manage complex implementations across multiple regions.”

Competence at the core
To support long-term modernization and reduce dependence on external expertise, RBI established a dedicated ‘Competence Centre’ (internally branded as the T24 Hub) based within Raiffeisen Tech in Poland. Raiffeisen Tech is a platform uniting IT talents, providing technical excellence to Raiffeisen Bank International Group. This centralized unit consolidates core banking expertise across the group, helping RBI execute implementations and upgrades with greater speed, consistency, and control. The idea stemmed from the bank’s desire to control core banking capabilities and ensure readiness for future transformation projects
The core banking system is the heart of our IT landscape. So, we wanted to centralize expertise to ensure quality and speed across the group.”
– Dr. Chadi Suleiman, Lead for International Core Banking Systems at RBI.
Piotr Kiryluk, Head of T24 Hub at the bank, added: “The main challenges were to identify what skills we wanted to develop, and at what scale of investment. Operating in multiple regions, each with distinct needs, it was important to take a considered approach, so we could ensure the Centre has relevance.”
The T24 Hub has already played a pivotal role in ongoing implementations, including Temenos Payment Hub at Tatra banka in Slovakia. Lessons learned from pilot projects are now being fed into future rollouts, supporting better planning, execution, and cost optimization across markets.
We’ve been able to embed expertise in local project teams, so there is consistency in how we evaluate, select and implement technologies across the group.”

Customer success as a catalyst
A key accelerator in RBI’s transformation has been the dedicated support from Temenos’ Customer Success team. From early planning of the T24 Hub to its certification, Temenos provided proactive support across training, stakeholder engagement, and governance.
“Having a dedicated Customer Success Manager was critical,” said Chadi. “They helped us connect with the right people across Temenos and kept the momentum going. The certification wouldn’t have happened without that level of partnership.”
Building the future
RBI is now working closely with Temenos to assess a group-wide cloud migration strategy for its Temenos Core installations. The T24 Hub will be instrumental in defining and executing this shift, helping RBI move from fragmented deployments to a harmonized, scalable, cloud-native core banking environment.
RBI’s long-standing partnership with Temenos, and the development of the T24 Hub in particular, reflects a shared commitment to transformation and scale. By investing in internal capabilities, the group is well-positioned to modernize further, whether that is with cloud, AI in Core Banking, or other innovations that emerge.
That extends the influence of the partnership beyond modernizing its systems, to shaping the future of banking across Central and Eastern Europe.
Temenos gives us the personal attention and collaboration we need to succeed.”
