Over the last few decades, the need for small and medium‐sized enterprises (SMEs) to rely on networking to get access to innovation and larger knowledge bases has become evident. This paper analyzes the birth and evolution of an Italian innovation community created by a group of SMEs searching for innovation. Coming from quite different fields, these SMEs converged around a challenging project in the field of biomedical and rehabilitation devices. The aim of the paper is twofold: (1) to investigate what type of competences and tasks have to be accomplished to effectively manage an innovation community (IC) and what managerial roles (promotors) emerge by crossing competences and tasks; and (2) to what extent community members' absorptive capacity (ACAP) influences their ability to acquire and exploit innovation generated by the community. Using an in‐depth longitudinal case study analysis, we identified three different stages in community evolution. We also studied which promotors' roles that emerged in each stage and determined their relationship both between each other and to community performance. Furthermore, we investigated to what extent an existing knowledge base in a specific domain and previous experiences in networking influenced community members' ability to exploit innovation. We found that a specific correspondence among competences and tasks is needed to guarantee community performance and that promotors should interact among themselves to enable the community to reach its goal. Concerning ACAP, we found that prior experience and familiarity in networking are not predictive of new knowledge exploitation.
