This paper explores how business consultants play a role as knowledge drivers and gatekeepers in Green Business Model innovation processes and how they facilitate and helps sustain knowledge networks in these processes. It contributes to the literature on knowledge networks by unveiling the benefits and challenges of using intermediaries in projects such as Greenbizz to recruit businesses. With an outset in the EU Interreg Kask project, Greenbizz, we investigate how business consultants connect businesses and researchers, creating new knowledge networks that involved parties benefit from in the form of resources and information. Analysing data from particularly semi-structured interviews, the paper looks into the benefits and challenges that follow this particular setup and what experiences can be derived to support Green Business Model Innovation processes. Our findings suggest that business consultants play a double role as intermediaries since they, on the one hand, guide the businesses towards relevant networks that can support them in innovating their business models in this project to become greener. On the other hand, they expand the researchers’ access to a larger pool of potentially relevant actors to include in their research on green business model innovation processes. However, the findings also unveil some of the challenges of using intermediaries in projects like Greenbizz to recruit businesses.
