About Us

Experience That Counts

Since 2004, we have specialized in output management – with a focus on StreamServe and OpenText Exstream. Over more than two decades, we have successfully delivered projects of varying complexity: from greenfield implementations and migrations to long-term system support.

We work predominantly remotely and have built extensive international project experience – in companies with locations in Germany, Austria, Switzerland as well as numerous other European countries, including France, Belgium, the Netherlands, Poland, Czech Republic, Spain, Italy, Denmark, Latvia, Norway and Sweden.

Our projects are typically long-term engagements: at least three months, often a year or longer. This way, we become an integral part of your team – with the knowledge of an internal employee and the independence of an external partner.

For specialized requirements, we can draw on a reliable network of experienced StreamServe consultants.

Honesty as a Principle
We say what we can do – and what we can't. Realistic assessments instead of empty promises.
Fast & Thorough
We ramp up quickly on new projects and truly understand the bigger picture – rather than just scratching the surface.
Full Commitment
Every project receives our undivided attention. Our clients are always informed about the current status.
Ownership
We take responsibility for our work and operate independently – with the goal of truly advancing your processes.
References on Request
Satisfied clients speak for us. We are happy to provide references upon request.
