In October 2018, the GREENTECH FESTIVAL was just an idea conceived by former Formula 1 World Champion Nico Rosberg and the Greentech entrepreneur Marco Voigt. But it all started back in 2008 when Marco Voigt and Alexia Osswald launched the Clean Tech Media Awards (now the Green Awards). In 2020, Deutsche Bahn then joined as an additional shareholder. In 2023 serial entrepreneur Tobias Assies becomes a new shareholder.
