ROI works both for international corporations and for well-known mid-sized and owner-managed companies. Long-standing relationships with our clients certify our high standards of quality. Our clients are based mainly in the following industries:
- Automotive Industry
- Industrial Suppliers
- Special Vehicles
- Aerospace
- Manufacturing and Engineering
- Pharmaceuticals and Medical Devices
- Process Industry
We have put together case studies for all these industries, which will give you a practical overview of our work.
In addition, our client journal DIALOG constantly runs reports on the latest projects.

ROI gives the project method. No prefabricated solutions are dished up, but custom solutions hammered out systematically.
