This research examines the influence of innovative leadership and an entrepreneurial mindset on building sustainable business development. Based on five business leadership case studies, the study aims to assess the degree to which innovative leadership, an entrepreneurial mindset, and a certain business leadership style account for organizational sustainability. The central hypothesis is that this combination is essential for sustained organizational progress. Using a purposive sampling approach, five cases across different industries and geographical locations were selected to provide insights and address the research question. The findings clarify the characteristics of innovative leadership, entrepreneurial mindset, and five different leadership styles. The results indicate that a proper fit between the leadership style adopted and the dominant innovative leadership and entrepreneurial mindset can enable the establishment of a unique organizational identity, fostering differentiation and continuous growth.
