Digital Platforms impose organizing logics on ecosystems. Dependent on their configuration, they enable certain practices, relationships, and value distribution among actors while preventing alternatives. Incumbent platforms often have a strong power to implement contested configurations since they control access to attractive user groups/markets. However, emerging platforms have a small degree of bargaining power in relation to key actors since they have not yet achieved such a position. Although numerous studies detail governance strategies for incumbent platform ecosystems, research on how platform providers navigate competing concerns in emerging platform ecosystems remain rare. We report on a study of the establishment and continuous dynamics of a digital platform used for service innovation. We inductively identify a pattern of the dynamics in this navigation process, locate four salient tensions driving these dynamics, and provide insights on how the platform provider navigated them.
