We present an in-depth case study of GVK Emergency Management and Research Institute, an Indian public-private partnership (PPP), which successfully brought emergency medical response to remote and urban settings. Drawing insights from the case, we investigate how the organization established itself through institutional entrepreneurship using a process conceptualized as opportunity framing, entrenchment, and propagation. The case and context highlight the need for innovation in organizational design and governance modes to create a new opportunity that connects state actors, private healthcare providers, and the public at large. We consider the role of open innovation and novel business models in creating these service platforms. The implications of our findings for the literature on PPPs, institutional entrepreneurship, inclusive and open innovation, and organizational design in base of the pyramid contexts are discussed.
