Our Story.

The Cardboard Revolution

How did KarTent start?

Jan & Wout met each other at the Cleantech Challenge, a course at the TU Delft. Jan had made a beach house out of Cardboard for his graduation project. When they stumbled upon a picture of Glastonbury camping after it had finished, the idea of KarTent was born.

Our goals

We strive to make our world a better place by looking at materials in a renewed way. We believe too many products are being created without thinking about the end of life scenario. Our products are designed exactly with this in mind.

Timo Krenn

Timo is a sharp multi-talent and enthusiastic polyglot. He started at PWC, but the suit felt too tight and cardboard boxes were more his style anyway. In his spare time, he likes to hockey or ski down some slopes (also in the famous Dutch mountains). Timo prefers a good espresso.

She likes to go through the country together with her dog made of copper and regularly ‘breaks the sound barrier’ in her weekends.

Maxime Durand

Maxime is our Frenchie in the office, with a heart for the environment and striving everyday to make this planet just a little bit better. He likes to smell his food before eating it, prefers cheese smellier than his socks and engages in strange activities such as petanques. Despite this, we simply can’t go without him. He prefers a black tea.

Bart van der Kant

Product Development

Bart is a warm-hearted and creative soul, with a strong passion for creating seemingly impossible cardboard constructions. His southern temperament and habits may sometimes cause confusion amongst his colleagues, but his brilliant cardboard inventions only cause amazement. Who else could be the inventor of the cardboard elephant but Bart?!
