The concepts of hybridity and governance have been an important line of research in the context of social companies and public institutions. The purpose of this paper is to explore these notions in the framework of hybrid communities of social innovation by showing the importance of intangible capital in the improvement of functional skills, techniques and strategies when directing people towards social innovation processes. The relevance of these skills are presented through the results of the HEDABIDE project, a piloting research experience focused on the design of hybrid communities of social innovation in the province of Gipuzkoa (Basque Country, Spain) in 2014. The results of this project show the implications of social interactive spaces in acquiring different skills, competences and capabilities for social innovation inside communities of learning and practice when addressing social problems, concluding with a series of learned lessons and new paths of future research.
