This chapter advances the sociocognitive perspective on ecosystem leadership, emphasizing the critical roles of managers, their cognitions, and their social interactions in shaping a shared ecosystem vision (sensing), achieving ecosystem-specific commitment (seizing) and maintaining ecosystem stability (reconfiguring). We explore which sociocognitive processes and capabilities likely underpin dynamic managerial capabilities. Towards this aim, we review the literature on ecosystem leadership, focusing on insights into sociocognitive dynamics to open new avenues for future research into the sociocognitive microfoundations of ecosystem leadership. We contribute to the literatures on ecosystem leadership and dynamic capabilities as well as to the sociocognitive perspective in management.
