Our Story

From living room to world stage

The idea was simple: build a company where as many IT enthusiasts as possible could bring their ideas to life. In 2003, itemis AG was founded in Lünen. From the very beginning, one thing was clear: we want to create a company that offers people an innovation-friendly and family-oriented platform where development is the top priority.

Today we are an independent IT consulting firm and provider of IT services and software solutions focused on efficient programming methods and software development projects. Since 2025, our headquarters is located in Dortmund. We are proud to have made itemis an international company without losing our local roots.

What itemis means to us

Sandra Wagener

At itemis I have been growing for over 14 years — professionally and as a person. The topics change, the technology evolves. And many colleagues who have walked this path with me have known me from the very beginning. That is not something to take for granted.

Justin Appel

I had already heard a lot of good things about itemis from people around me – and when the apprenticeship profile on Kununu and the website were both so convincing, I just applied straight away.

What has kept me at itemis for over 20 years? The variety of projects and challenges, a team that truly sticks together – and the fact that today we are working on one of the most cutting-edge AI-driven development projects out there.

Dennis Mende

I believe great software is built where people collaborate openly, learn from each other and take responsibility. At itemis, that's not just a phrase – it's something I've experienced every day for over 12 years.

What sets us apart

Clients want more than good day rates. They want a partner who stays calm in a crisis, knows when to let things slide, and is honest when something won’t work.
In sync and motivated

In sync and motivated

We staff projects with people who have worked together before – and with engineers who are motivated because we take them seriously. Every project feels the difference.

Resilient when things get tough

Resilient when things get tough

Audits, release weeks, crisis sprints – we stay calm, roll up our sleeves and work through the late shift. Reliability that isn't written into the contract.

Working together as equals

Working together as equals

No diplomatic loops, no manoeuvring. We say openly when something won't work – and listen when you tell us the same. A sparring partner, not just a supplier.

Performance over sales pressure

Performance over sales pressure
