What happens after the notary appointment? Marvin Dreesmann, an employee at the Justus Liebig University in Giessen, has just founded a company and launched the children's book series Marmelin in April. At the "Gründerstammtisch Gießen" on May 12 from 7 p.m., he openly reported on current challenges in a young start-up! A few days ago, the start-up celebrated the launch of its first project at www.marmelin.de. The first part of the children's book series Marmelin and the corresponding merchandise are now available. The book series aims to sensitize children of reading age to socio-political issues such as refugees, pandemics and pollution of the world's oceans.
