Public‐private collaborations, or hybrid organizational forms, are often difficult to organize because of disparate goals, incentives, and management practices. Some of this misalignment is addressed structurally or contractually, but not the management processes and practices. In this study, we examine how the coordination of these social and work relationships, or relational coordination, affects task performance and the creation of social value. We employ a dyadic perspective on two long‐term relationships that are part of a wider ecosystem. We illustrate the social value creation process, identifying mutual knowledge and goal alignment, as necessary to create relational coordination. We find that the degree of professional embeddedness moderates the link between coordination and task performance, and explore the role that organizational and ecosystem experiences play. We develop a model of how relational coordination influences social value creation in hybrids. The findings have implications for social value creation, hybrid collaborations, and organizational design.
