In high-velocity sectors such as artificial intelligence, biotechnology, fintech, clean energy, and blockchain, founders routinely face uncertainty, ethical complexity, and strategic ambiguity. Entrepreneurial courage, the capacity to act decisively and ethically under pressure, has become a critical yet under-theorized competency. This paper develops a multidimensional framework of entrepreneurial courage, drawing from cross-sector literature and anchored in both Entrepreneurial Orientation and Effectuation Theory. Through thematic synthesis and empirical inquiry, the study identifies five interrelated dimensions-moral, strategic, ethical, resilience, and emotional courage-that shape founder behavior in emerging technology ventures. The EcoM model introduced herein offers a comprehensive lens to understand how courageous leadership fosters responsible innovation, stakeholder trust, and adaptive governance. By bridging fragmented constructs and offering real-world insights, this research contributes a practical roadmap for cultivating courage as a strategic asset in complex innovation ecosystems.
