Our Team

In early 2017, Klaus Wiesen, Christoph Wiesen, Dr. Thorsten Merten, Willem Bulthuis, and Dr. Markus Werner founded sustainabill to establish climate and human rights protection in global supply chains.


We are thought leaders when it comes to sustainability in supply chains. The company idea and our expertise originate from the research of the Wuppertal Institute, one of the world’s leading think tanks for applied sustainability research. Until the founding of sustainabill, Klaus Wiesen conducted research there and provided science-based consulting to companies.


Today, we are a growing team that combines leading technology and sustainability expertise. We are united by a strong belief that the transformation to a sustainable business world cannot succeed without sustainably designed supply chains. We want to be part of the solution to enable a sustainable business world and to master one of the biggest challenges of the 21st century!
