Our history
Christian and Stefan Nohel are the two managing partners of brainbows. They are supported by two female partners: Monika Langthaler and Maria Vassilakou.
brainbows was founded in 2000 by Monika Langthaler and Christian Nohel, who had previously worked together in science and politics for over 14 years.
In 1990, they joined the newly formed Green movement. Monika Langthaler was the youngest member of the Austrian parliament until 1999, while Christian Nohel was a political advisor in the Green Parliamentary Club. After ten years in politics, it was over – and the two started their next passion project: brainbows.
Monika and Christian were among the first in Austria to introduce sustainability into public consciousness and corporate boardrooms, advocating for a pragmatic and economically viable approach. Initially dismissed as a ‘niche topic,’ their foresight has been validated: sustainability and the green transformation are now central to EU economic policy.
Stefan Nohel began his career at Brainbow in 2018 as a consultant specializing in energy, climate protection, decarbonization, and strategy development. In 2024, he purchased shares and succeeded Monika Langthaler as managing director the following year. He and his uncle, Christian Nohel, have run the sustainability agency since then.
Maria Vassilakou became a partner at brainbows in March 2024. The former deputy mayor of Vienna is particularly committed to urban transformation strategies and transition management with cities, companies, and organizations.
