Mainframe is ready for disruption.

Not ready for full modernisation yet?

Start with discovering the obsolete parts of code that are no longer in use


Let us take over your L2 and L3 support on top and save extra 30 % on support costs.


We provide modernization capacity across multiple platforms, in a system that allows you to decide when and how to embark on modernization process. Solutions we build for you can be gradual and reversible, and thus easier to implement. You can even start with discovery only, to see where the most inefficient parts of  your code are. We also provide support and development to complete our services to full extent.


We create an outline of strategic routes in a roadmap, providing visibility on the risks and benefits of two main modernisation approaches:

Interpretation = gradual implementation without “big bang” approach

Code compilation and transfer to Java or other modern programming language.


Our proprietary build tool Discoverer visualizes gathered mainframe data, JCLs, OPCs, Cobol and PL1, FTP and other attributes and compiles them in a structured manner.

The analysis output is uploaded to an ArchiMate repository.
