Interview with Tomasz Marak
Sales Manager at Percall Group Siemens Partner
For industrial companies navigating complex, multi-country transformation programs, having the right partner makes all the difference. We spoke with Tomasz Marak, who coordinates commercial strategy across Europe at Percall Group, about what it means to drive real change in industrial organizations, and what sets Percall Group apart in that journey.
Can you introduce yourself and your role at Percall Group?
I’ve been working at the intersection of engineering, manufacturing, and enterprise software for about 20 years now. At Percall Group, I manage commercial strategy and growth initiatives across Europe, which means supporting industrial companies through complex transformation programs and helping them build the business case for technology investments like Siemens Teamcenter.
But my role goes beyond the commercial side. It’s really about shaping how organizations adopt these solutions so that they create a true digital backbone, one that enables faster innovation, better decisions, and stronger operational control.
What does the Siemens partnership represent for Percall Group, and what makes you different from other partners?
The partnership is central to who we are. But what actually differentiates us is our ability to operate at three levels at the same time: the technology itself, the operational reality of engineering and manufacturing, and the business value, translating transformation into measurable outcomes.
Many players in the market are strong in one of those dimensions. Our strength is in connecting all three into a coherent journey for the client.
Looking forward, I see the partnership evolving toward something bigger, co-creating transformation models where digital continuity runs across the entire product lifecycle, with real-time decision-making and tight integration between engineering, manufacturing, and service.
Percall Group operates across France, Benelux, and Poland. What's the thinking behind that footprint?
It’s not just geographic expansion. The combination of those markets is deliberate, it puts us close to major industrial decision canters, gives us access to strong engineering and delivery capabilities, and allows us to scale across complex, multi-country programs.
The real value comes from how we connect those entities. Locally, we stay close to clients, understanding their context, their constraints, their culture. At the European level, we deliver with shared methodologies and consistent standards. That allows us to support multi-site deployments, global templates, and transformation programs that span multiple countries and functions. It reflects the way our clients themselves are evolving.
What keeps you motivated after 20 years in this field?
What drives me is the scale of what’s shifting. We’re moving from document-based, fragmented environments to connected, data-driven ecosystems. That’s not a technology change, it’s a transformation in how decisions are made, how teams collaborate, how value is created.
Being at Percall Group means being in a position to actively shape that shift across Europe. What makes it meaningful is the combination of strategic complexity and very concrete results. When you see a client move from complexity to control, that doesn’t get old.
