Thriving entrepreneurial ecosystems are characterized by a free flow of experiential knowledge between seasoned and novice entrepreneurs. While extant view recognizes the importance of these knowledge sharing networks, little research has been done to understand the process through which such networks might emerge in a nascent ecosystem. This paper addresses this gap by exploring the work of iSPIRT, a software product industry think tank in India that has been systematically nurturing such a network. The study work reveals that three interlocked processes (Curation, Interaction and Expansion) involving novice entrepreneurs, experienced entrepreneurs and the entrepreneurial connector (iSPIRT) creates a sustainable knowledge sharing network. The study isolates the unique role played by each ecosystem actor through these processes, providing important insights to practitioners and policy makers.
