We analyzed the role of broker of three cases of innovation promotion in the rural sector. Their profile, their position in the network and the context in which they operate were considered. It was found that the greater the tendency to allow the participation of local or exogenous actors to the territory, their influence decreases and the relationships in the network increase. This tendency is influenced by the broker’s profile and the context in which they operate. Identifying these elements is relevant for the sustainability of initiatives that promote the creation of innovation networks.
