CREDITAS Bank, in line with its strategic goals and ambition to strengthen its market share, successfully acquired the former Expobank, which, after rebranding, began operating under the new name MAX Banka. The next step in the acquisition process was the merger of both institutions. The goal of the merger was to build a modern digital banking infrastructure that enabled the unification of organizational structures, product portfolios, internal processes, service channels, and the client base.

The Allianz Trade Group underwent a major digital transformation, centered around a generational upgrade of the core system and its associated satellite platforms across the entire product portfolio. The transformation affected all products—local variants were gradually converted into unified core products of the group. A key part of this change was the consolidation and standardization of critical business processes. The newly introduced unified IT Mate Platform created a technological foundation for more efficient operations, product management, and process automation. The consolidation of the product portfolio and the unification of business processes across regions are delivering higher operational efficiency and an improved customer experience.

ČSOB decided to modernize its core banking system, which was no longer able to fully respond to the bank’s growing needs. The main goals were to reduce time-to-market for new features, simplify system management, and establish a strong foundation for further development. The transformation also included optimization of key processes such as print outputs and user access management. Since the same system was used by ČSOB in both the Czech Republic and Slovakia, the modernization was carried out in a coordinated manner across both countries. The central management and development were handled by the Czech team, which operated the system for both entities. The Slovak branch played a key role as the originator of business requirements and the future user of the solution.
