Peter Bartholin and William Ahlefeldt, both originally from Denmark, launched Greenworlder in Luxembourg. Both Peter and William wanted to make a difference in environmental action and came up with the idea of a social platform dedicated to sustainability. Through this platform, people who had little knowledge about climate change could learn more and begin to have an impact as well. They were joined by Daniel Klemetz as a CEO, an experienced telecom professional with a broad experience in strategy, procurement, and governance.
