Temenos and MAINSYS to deliver digital banking solutions, as banks focus efforts on digitization

Temenos (SIX: TEMN), the banking software company, today announces a partnership with MAINSYS, a leading provider of IT services to the Belgian financial services sector. The partnership brings together MAINSYS’ knowledge and experience in providing digitalization services for the banking sector, and Temenos’ digital end-to-end banking technology packaged with global best practices.

Regulations, changing customer behaviors and the arrival of new fintech competitors are forcing banks to reinvent their business models.

This can only be achieved with future-ready technology, built on an open and flexible platform that allows for continued innovation. T24, in combination with MAINSYS’ industry expertise and local presence, will enable banks to embark immediately and confidently on the journey to provide a differentiated, highly contextualized and personalized service to customers with rapidly evolving needs.
