Dialogue marketing thrives on strong connections.
That is exactly what Trebbau direct media stands for.
Since 1936, we have been helping companies and organisations reach their target audiences with precision and turn communication into measurable results. Today, we bring together data, media, print, production and dialogue marketing to create solutions tailored to our clients and their goals.
In doing so, we rely on what has proven its value over many years: personal advice, in-depth expertise and a partnership that goes beyond the individual project.
Experience that looks ahead.
For us, 90 years of company history do not mean clinging to tried-and-tested ways. They mean knowing what works while remaining open to new approaches.
Our clients benefit from specialised teams, direct communication and a broad range of services spanning dialogue marketing, target audiences, data, media and production.
We have worked with many of our clients for years, and in some cases even decades. This creates trust and gives us an in-depth understanding of markets, target audiences and requirements.
What matters to us is this: solutions do not need to be as complicated as possible. They need to fit the objective.
Three values that have guided us for many years
Tradition
Trebbau has been in business since 1936 and remains family-owned to this day.
What began with the collection of addresses has evolved over generations into a dialogue marketing agency with a comprehensive range of services.
Our history has shaped us – above all through reliability, personal relationships and our commitment to taking responsibility for our work.
Innovation
Dialogue marketing is changing. Media are changing. Data and technology are opening up new possibilities.
That is why we continue to evolve as well.
We assess new approaches and technologies and combine them with proven methods wherever they create genuine added value for our clients. Not every innovation is automatically an improvement. What matters is whether it makes a campaign better, more efficient or more successful.
Expertise
Good results are achieved by people who know their craft.
At Trebbau, specialists from different disciplines work closely together – from target audiences and data to media planning and buying, production, lettershop services and distribution.
This allows us to view every task in the context of the entire campaign rather than in isolation.
Experience is good. Sharing it is better.
Behind Trebbau is a team with extensive experience, specialist expertise and a keen understanding of our clients’ requirements.
Different disciplines work together under one roof. This simplifies coordination, shortens communication channels and enables us to develop solutions in which every element works seamlessly with the next.
Above all, it means that our clients have dedicated contacts who know their projects and take responsibility for them.

Trebbau is setting the course for the next generation.
In 2026, a new chapter began for Trebbau: Karl-Peter Trebbau and Justin Hackenbroich jointly assumed management of Trebbau direct media GmbH.
This brings together many years of experience and continuity with fresh perspectives.
Justin Hackenbroich has close ties with both the Trebbau family and our company that go back many years. He knows its values, culture and distinctive character, while also contributing new ideas and fresh impetus for its continued development.
What remains unchanged is our commitment to quality, personal service, reliability and partnership.
Our experienced team and trusted contacts remain the foundation of our work. At the same time, we want to embrace new opportunities and continuously develop our services and processes.
Much has changed. Our commitment remains.
