RSU – a success story

It all started in the fall of 2001. Eight Landesbanken (German federal state banks) and DekaBank joined forces in a cooperation. Its purpose: ensure top quality and regulatory compliance for internal rating procedures. In the years that followed, this project group created the sophisticated software tools and applications its members were looking for.

In 2003, RSU became an independent enterprise. What used to be project partners are now company shareholders. In (further) developing and continually reviewing our products, we still benefit from their expertise and wealth of experience.

Today, we are a leader in our field. Our client base comprises banks of all specializations, financial service providers, and also industrial companies. We provide them with efficient solutions that extend far beyond internal rating.

RSU is a member of the BVI (the association of the German investment funds industry) and a partner to the Leipzig Insurance Forums.
