Your mainframe is ready for disruption. 

Modernise your legacy systems for greater business agility.


Move your mainframe application to an open system through a gradual and  reversible process.


Not ready for full modernisation yet? Start by discovering obsolete code that is no longer in use.


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


We are able to modernise across multiple platforms in a system that lets you decide when and how to embark on the modernisation process. The custom solutions we build can be gradual and reversible, and thus easier to implement. You can even start with just discovery to see where your most inefficient code is. We also provide support and development to complete our full line of services.


We have created a roadmap outlining strategic routes, providing a visualization of the risks and benefits of the two main approaches to modernisation:

Interpretation = gradual implementation without the “big bang” approach

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


Discoverer, our proprietary build tool, visualizes 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.

Discoverer is our proprietary build tool.



Your data can be stored on-premises or in a cloud environment. Discoverer is prepared for any scenario you may be familiar with, utilizing HTTPS protocols to make sure all communication is secure.



We built Discoverer using top-grade open source technologies, employing the latest features that help end users utilize the best calls.


As a part of our integrated services, we also provide support, leveraging our years of ITIL experience. Our team will take ownership of your transformed applications to provide real E2E services that will help minimize the impact and optimize the benefits of modernisation.
