Hexonic, Germany and the Next Stage of Growth – A Conversation with Mariusz Grelewicz

Mariusz, since July 2025 you’ve been working at Hexonic as Sales & Marketing Director, and since February this year you’ve also taken on the role of Managing Director at HEXONIC Deutschland GmbH. When you think about the company’s development today, what is your main point of reference?

For me, it always comes back to the foundations of the brand. Hexonic isn’t just a story of the “last few years” — it’s an organization built over nearly four decades, since 1988. And you can feel that experience in the way we work.

In our 2025–2028 strategy, we clearly define what remains constant: growth, innovation, and trust.

We approach growth step by step — including in international markets — without shortcuts. We see innovation in very practical terms: it has to deliver measurable results — faster implementation, greater safety, and less risk for the customer. And trust? That’s the essence of B2B for me: partnership-based relationships, predictability, and accountability for results.

“We meet customer expectations by delivering innovative heat exchangers.”

That sounds very strategic — but what does it look like in everyday practice?

That’s exactly the point: it’s not just a PowerPoint slide. It’s a mindset.

We don’t refresh things just for the sake of refreshing them. There’s a lot of passion in our organization for continuous improvement — and that passion comes from understanding innovation as real, tangible change: improving processes, shortening lead times, reducing risk on the customer’s side, and increasing predictability.

That’s why we respond quickly to market needs, invest in technological development, and build long-term partnerships. That’s part of Hexonic’s DNA.

Germany: A Market We Believe In — and Want to Grow In

Let’s talk about Germany. Why is this market so important to you?

Because Germany is one of the most demanding — but also most rewarding — markets in Europe. It’s the largest economy in the EU, with a powerful industrial base and a very high technical culture. And wherever you have industry, power generation, process cooling, data centers, and system modernizations, heat exchange plays a critical role.

Put simply: it’s a large-scale market that values exactly what we stand for — consistency, predictability, strong relationships, and accountability for results.

What tangible proof do you see of its potential?

You can see it clearly in the structure of inquiries and the segments growing fastest in Germany: Energy & Cooling, Food & Beverage, and Data Center & HVAC. These aren’t random areas — they reflect broader market trends: energy efficiency, heat recovery, process stability, and infrastructure development.

And importantly, this is a market that doesn’t look for the loudest promises. It looks for partners who deliver and build relationships for the long term. We believe in that — and that’s why we want to strengthen our presence there.

People You Simply Enjoy Working With

What role does the local team play in all of this?

A crucial one. We have an experienced local sales team covering key market segments:

• Jörg Bierwirth — Data Center & HVAC
• Frank Pompetzki — Food & Beverage
• Jens Jüngel — Energy & Cooling

They understand the specifics of the German market, truly know their customers’ needs, and are able to lead discussions at the project level — not just the product level.

Equally important is our technical and operational support. Michael Müller (Technical Sales Support) provides expert support during the quotation and project execution phases, translating customer requirements into concrete technical solutions.

My appointment as Managing Director of HEXONIC Deutschland GmbH is part of a planned effort to further strengthen our presence in the German market. Today, my priority is to clarify direction, reinforce support structures, and create the conditions that allow our local team to move faster and operate more effectively — in a way that remains predictable and reliable for customers and partners.

Mariusz’s Experience and the Development of the German Subsidiary — In Concrete Terms

You mentioned setting direction and scaling operations. Which parts of your experience are proving most valuable in Germany right now?

There are many, but three stand out.

First, managing large budgets and full P&L responsibility. As CEO/Managing Director at Amiblu Poland, I was responsible for over PLN 300 million in annual sales and the overall financial performance of the organization.

Second, building structures and teams. I managed an organization of more than 400 people, including extensive sales and marketing teams.

Third, integration and process management. I led a post-merger integration (PMI) project, implemented a goal-based management approach (MBO), and introduced CRM tools — all while improving operational efficiency.

On top of that, I gained valuable international experience as Managing Director in the UK.

Germany values structure, consistency, and predictability. It’s a market where you win in the long run — and that’s exactly the way I like to work.

One sentence to describe Hexonic today?

Nearly four decades of experience — and a very clear direction: growth built on trust, including in Germany.
