The question of how new organizational forms are created remains an unsolved problem in new institutional theory. We argue that one important way that new organizational forms emerge is through a process of bridging institutional entrepreneurship, which involves an institutional entrepreneur combining aspects of established institutional logics to create a new type of organization underpinned by a new, hybrid logic. Building on an in‐depth case study of a social enterprise in the United Kingdom, we present a model of the institutional work required for this type of institutional entrepreneurship. The model highlights the multilevel nature of bridging institutional entrepreneurship, showing that it entails institutional work at the micro‐, meso‐, and macrolevels. The study contributes to the literature by examining an important way that institutional entrepreneurs create new organizational forms; shedding light on the relationship between individual, organizational, and societal level institutional processes; and exploring the relationship between entrepreneurship and institutional entrepreneurship.
