Target groups are our passion

Dialoghaus is an independent, owner-managed company that has been successfully planning and supporting dialogue marketing campaigns for customers in a wide range of B2C and B2B industries since 1997.

Our core competence is the acquisition of new customers via dialogue media – with measurable success and international know-how.

We combine media, analytical, and dialogue marketing expertise from a single source – that’s what makes us so special. To ensure the success of your advertising campaign, our experts work closely together and guarantee you individual target group consulting, effective planning and implementation, and optimized purchasing of media and advertising materials.

From an address publisher to an innovative dialogue marketing consultancy

With a focus on postal addresses and mailing-based dialogue marketing, Dialoghaus GmbH was launched in September 1997 by the five founding partners Jürgen Grundmann, Johann Kuhlendahl, Juliane Jung, Jeannette Kuhlendahl and Carolyn Gelsomino.
The desire to think and develop dialogue marketing with customers and partners, to create innovative solutions and dialogue marketing services for the greatest possible customer benefit, united and inspired the team. In the same year, the Dialoghaus car database and the large SAT.1 viewer database was created and marketed exclusively by Dialoghaus. The first clients who trusted us were Eurolotto and Publicis Dialog with Aktion Mensch, for whom we are still working today – after more than 20 years.
