1983 - 1988

In 1988, the company expanded its reach by acquiring the renowned classifieds publication "Kurz und Fündig" based in Munich. This marked the beginning of a series of strategic moves as they furthered their presence in the market by purchasing, founding, or investing in "Das Inserat" in the Rhine-Main region, "Such & Find" in the new federal states, "Alles" in Franconia, "Pinnwand" in Wuppertal, and several other notable ventures.



1988 - 1996

From 1988 to 1996, our company dominated the market in Germany with an impressive 50 percent share. But our influence didn't stop there. We also held shareholdings and proprietary interests in nine other countries, including the Netherlands, Great Britain, Ireland, Finland, Switzerland, France, Portugal, Australia, and South Africa. Our global expansion efforts didn't go unnoticed either. In 1996, we were honored with the prestigious "Innovative SME" prize for our exceptional ability to expand abroad while simultaneously creating more job opportunities in Germany.

Jutta Kübler, Bernd's wife, played a pivotal role during this time, making a significant positive contribution to the company's success.
In December of 1994, a new addition to the family arrived as Jutta and Bernd welcomed their son Karsten into the world.

During the dawn of the new millennium, the publishing house boasted a thriving workforce of 1400 individuals stationed at its headquarters in Lampertheim. Additionally, around 2000 talented professionals were dispersed across nine different countries. As the new millennium approached, a prestigious Bank evaluated the company's worth to be in the hundreds of millions of dollars at the turn of the year 1999.
