Generation Z entrepreneurs show a strong interest in building businesses, yet many experience business performance instability due to limited managerial experience. Entrepreneurial leadership is therefore considered a strategic factor that may enhance business management capabilities, decision-making efficiency, and performance sustainability. The relationship between Entrepreneurial Leadership and Business Performance among Generation Z entrepreneurs in Indonesia is examined in this study. A quantitative cross-sectional design was employed, involving 254 Gen Z entrepreneurs selected through purposive sampling. Entrepreneurial leadership was measured using the theoretical framework proposed by Gupta et al. (2004), and business performance was assessed using the Balanced Scorecard dimensions. Questionnaire data were analyzed using simple linear regression to assess the effect of Entrepreneurial Leadership on Business Performance. The analysis revealed a positive and statistically significant effect, as indicated by the regression coefficient (β = 0.608), t-value of 12.074, and significance level below 0.001. These findings provide empirical evidence of the role of entrepreneurial leadership in supporting business performance among Generation Z entrepreneurs in Indonesia. Business performance may also be influenced by various other factors beyond the model examined in this study. The findings may serve as a basis for mentoring programs, training, and development strategies aimed at strengthening entrepreneurial leadership, improving business performance, and supporting business sustainability among young entrepreneurs.
