In this contribution, we introduce the concept of Positive Innovation Networks (PINs) as a framework to understand processes of co-creation and open collaboration involved in digital social innovation. Drawing on positive psychology, an emerging field focused on the empirical investigation of optimal human functioning, we deconstruct two assets that PINs can leverage to achieve transformative social change: networked flow and positive psychological capital. Networked flow is an optimal group experience that can unlock the creative potential of a PIN by maximizing the “we-intention” of its members. Positive psychological capital refers to the capacity of a PIN’s core team to accrue and spread hope, efficacy, resilience, and optimism. We show how these positive psychological resources can be measured and developed for improving PIN performance. Finally, we summarize the key traits of PINs and illustrate them through a case study.
