"The paper provides empirical evidence on impediments of the emerging social impact investment field in Germany. The study is based on 19 in-depth interviews with social impact investing funds, investment advisors, and social entrepreneurs as investees. It takes an explorative approach because of the nascent stage of research on the subject. By systematically relating the perspectives of the actors involved, the study gives a broad empirical picture on the major challenges for social impact investing in Germany. Results reveal nine critical problem areas we have arranged along three dimensions: financial returns, social returns, and relationships and infrastructure."
