Erwin is one of the „Founding Fathers“ of Impact Investing in Germany. After several years in traditional investing at Wellington Partners, he launched his own start-up incubator. In 2002, he initiated the founding of BONVENTURE, the first impact investing fund in the German-speaking realm, with a group of socially committed investors.

Since then, Erwin has continued to drive the development in the impact sector. As a business economist and with a PhD in statistics, he is one of the leading minds in the industry, especially in financing models for startups and data-driven impact analyses. For example, he co-authored the first uniform standard for impact reporting and is regularly interviewed by trade and consumer media on the latest developments in impact analysis.
