About Schuberg Philis
Industry: Information Technology & Services
Company size: 201-500 employees
Some systems just have to work. They keep power grids stable, logistics moving, payments flowing, and vital public services online. You don’t hear much about them when they work, but when they stop, the impact is immediate, visible, and far-reaching. That’s exactly the kind of work we do. We design, build, and run IT systems that must be reliable, secure, and uncompromising because people depend on them every single day. We call it mission-critical IT. At Schuberg Philis, we go beyond traditional IT services by delivering promised outcomes, not just projects. Our Plan-Build-Run model means the same team takes ownership from start to finish: no handoffs, no middlemen. It’s how we’ve made 100% customer satisfaction not a goal, but a requirement. And it’s why 99.9% of our projects are delivered on time and on budget, helping customers realize solutions that are better, cheaper, and faster. Our engineers bring deep expertise in cloud, data & AI, software, and security, not as abstract offerings, but as the means to solve business-critical challenges. Whether it’s banks handling millions of transactions, logistics firms keeping supply chains running, or energy providers maintaining grid stability, customers trust us when failure is not an option. What sets us apart? - We engineer outcomes, not just deliver technology. - Our autonomous teams carry end-to-end responsibility. - We focus on long-term resilience and impact. This approach has made us the #1 ranked IT company in the Netherlands, according to Whitelane Research. Since 2000, we’ve built enduring partnerships across vital industries, delivering secure, scalable, and seamless solutions that keep society moving. We’re expanding across Europe with one clear mission: to be more than an IT provider. We’re a partner who understands your business inside out, and who is fully invested in your success.
