The deltaPD UG (haftungsbeschränkt) - project "Marmelin" is a young startup with the business headquarters in Düsseldorf.
Our first project, the Marmelin series, offers a child-friendly treatment of current social challenges in the form of exciting adventure stories.
This gives parents the opportunity to teach their children about current topics such as refugees, diseases or environmental protection and to convey open, social and peaceful values. The main characters of our exciting stories are Marmelin, Arin and Kartoffel.
