Depth over buzzwords. Tools over presentations.
When I founded itemis over twenty years ago, the idea was simple: engineering not as a commodity, but as a craft. Today we are many times larger — but the same idea still drives us. We stay with what we truly know, keep teams together, and take the word “reliable” more seriously than most people say it.
My benchmark for AI? It multiplies substance. Those without it get nothing but well-formatted emptiness, despite AI. But those who bring experience and expertise can achieve more with it today than ever before. itemis has embodied this since its founding: deep engineering expertise and the discipline to turn innovation into tangible results. With AI, we can multiply exactly that substance — across far more areas than software development alone.
Four promises
What sets us apart
Clients expect more than competitive rates. They want a partner who stays calm under pressure and acts pragmatically when it matters.
Cohesive and motivated
We staff projects with cohesive teams and engineers who are motivated because we take them seriously. Clients notice the difference from the very first sprint.
Resilient under pressure
Audits, release weeks, crisis sprints — we stay calm, maintain focus and deliver under pressure every time. Reliability that goes beyond the contract.
Direct and at eye level
No diplomatic detours, no politics. We communicate directly, listen carefully and speak plainly when something isn't right. A sparring partner, not a supplier.
Performance over sales pressure
We invest in the partnership, not the sales pitch. Those who know us know: at itemis, reliability is not something we promise — it is something we demonstrate.
