While rising, Sustainable Entrepreneurship (SE) prefers developed countries and ignores the specific challenges of developing countries with dynamic and unpredictable circumstances. To fill this gap, our research investigates how entrepreneurs create and develop sustainable enterprises in such settings. We employ an in-depth qualitative study of KarmSolar, an enterprise emerging from the Egyptian Revolution. We identify four navigating phases of the venture creation and development: Revolution Inspired Entrepreneurial Venture Creation, Foundational Resilience Strategies, Strategic Entrepreneurial Adaptation and Growth, and Sustainable Institutional Legacy. This study combines the subjective emphasis of discovery theories with the objective function of external enablers and the dynamic nature of Effectuation. Our multilevel model shows how external enablers, venture development, and entrepreneurial actions interact, giving SE literature a new perspective in changing contexts. Our research emphasizes transitioning from a company to a sustainable institution, adding a forward-thinking, sustainable perspective to Sustainable Entrepreneurship literature.
