Greenduck Gmbh

Since the foundation in 1978, kriener-potthoff continuously adapted its business activities to the changing market conditions. We have now expanded our portfolio and added new capabilities after Philip Kriener joined us as a new partner and managing director. We believe this new line-up consequently has to lead to a new corporate identity, including a new name and new appearance.

kriener-potthoff communications gmbh is now GREENDUCK GmbH.

The new GREENDUCK GmbH stands for



Corporate Identity, Corporate Design und CRM concepts.


Webdesign and IT services.


The online platform for home & garden. For professionals and hobbyists alike.


The online store featuring selected products for home & garden.


The revolutionary soil amendment for professionals and hobbyists.
