Meet today… Andrzej Wilczewski: Transformation isn’t just about tools – it’s about mindset.

Since December 2024, Andrzej Wilczewski has been Head of Key Account Management at Xella Germany. With over 13 years of experience in the company, he brings a dynamic, open-minded approach and a deep passion for architecture. In this interview, he shares his thoughts on transformation, teamwork, and why building for eternity is more than just a metaphor. 

08 October, 2025

Andrzej, how did you join Xella? 

I studied architecture and started my career as a project and construction manager in Kazakhstan, and the UAE. In 2012, I joined Xella by accident, I googled “Xella” as I participated in the student competition earlier twice, not knowing what the company really was. Of course I knew our products, especially YTONG. I began my career as a technical advisor in Berlin, where I supported construction professionals in the region. I was 29 at the time – the “youngster” on the team. Over the years, I’ve taken on various roles, Key Account Manager. What keeps me at Xella is the opportunity to grow and shape things, in a market with challenging customers: architects, developers, construction companies, general contractors and traders. I know the company inside out – not just in Germany, but across many countries. 

What are your responsibilities as Head of Key Account Management?

I lead the strategic development of our key customer relationships and manage a team that’s tailored to different markets and needs. It’s not just about sales – it’s about structure. Who brings which strengths? How can we assign roles and build teams that truly perform? I see myself as someone who’s ready to restructure when needed – an ambitious person who’s not afraid to challenge the status quo. 

What are you currently working on?

In addition to my core responsibilities, I continue to support our licensing business, especially in technical issues. It has become a third pillar of my work and gives me valuable insights into international operations. It gives us benefits in Germany, how can we learn from our other colleagues abroad? I’m also deeply involved in shaping the transformation of our sales organization – making it faster, more customer-focused and modern. 

How do you view the transformation at Xella?

Germany has huge potential. But transformation isn’t just about new tools – it’s about mindset. We need a culture of open feedback, where people can speak honestly. Not everyone has the same strengths, and that’s okay. What matters is defining roles clearly and building teams that complement each other. Customers experience real value through solutions that are not only technically advanced but also thoughtfully designed and planned by highly driven teams.  

What makes Xella a good place to work for you? 

The international scope, the openness, and the chance to make a real impact. I love being part of a team that’s dynamic and positive. That energy shapes how I see Xella – as a place where you can truly contribute. New colleagues learn a lot from the experienced ones. 

What’s most important to you in your work environment? 

Honest communication. I like to speak openly, and I believe that should be possible everywhere. I’m also motivated by a fast-paced, modern environment where we don’t just react – we take initiative. The desire to succeed is conditio sine qua non! 

How do you spend your free time? 

I travel a lot – for work and pleasure. Wherever I go, I explore the local architecture and urban design. It’s more than a hobby; it’s a source of inspiration. I’m also passionate about sports, especially team sports. They’ve taught me skills I still use today: sacrifice, teamwork, discipline and communication. These lessons learned remain.

What kind of legacy do you want to leave behind? 

I want to build something that lasts. Like the ancient builders who created structures for eternity. I once worked with the German Archaeological Institute on a project in Baalbek, Lebanon, where we discovered the largest stone ever used in construction. Later, an even bigger one was found – 20 x 6 x 5 meters, weighing 1,650 tons! That kind of history fascinates me. I want our work to leave a mark – in the best possible way.
