This research highlights the critical role that entrepreneurial capital (EC) plays in organizational development and resilience by examining the connections between EC and the success of new joint ventures (NJVs) in developing nations. Corporate social responsibility (CSR) is becoming more popular in the early phases of a company’s growth because of its capacity to improve credibility and competitive differentiation. Traditionally associated with well-established corporations. This study uses a mediated-moderation model to explore theories on how EC affects the disruptive innovation, economic, social, legal, and environmental sustainability of NJVs. Using quantitative survey data from 270 NJVs, this paper highlights the strategic interdependencies influencing NJV trajectories, as well as the functions of disruptive innovation and CSR. The findings demonstrate that EC greatly enhances NJVs performance in every category, promoting CSR and innovative projects. NJVs benefit from early CSR participation because it reduces risks and boosts entrepreneurial vitality. Disruptive innovation transforms EC into measurable performance advantages. This study has important policy and management implications because it shows that NJVs can stay ahead of the competition and improve their performance by strategically using EC for CSR and innovation projects. Overall, this study emphasizes how crucial CSR is to the startup environment, supporting resilient and long-term growth in emerging economies.
