We Make Software

Our German-made products are sold all over the world. We provide information management systems for companies and administrative bodies.

Designing Digital Innovations

We help companies quickly locate information internally, manage it transparently, distribute it in a targeted way, and securely archive it. For nearly three decades, OPTIMAL SYSTEMS has been developing software solutions for enterprise information management (EIM), helping companies streamline their processes and reach decisions more effectively.

Our software solution is called enaio®. Whether it’s applied as a modular ECM solution or as a scalable EIM framework, enaio® guarantees unrestricted access to a heterogeneous data landscape. enaio® is customizable and helps you become more efficient, both within individual departments as well as throughout your company as a whole.
