Leadership and entrepreneurship have often been associated to the ability of guiding ventures, but less to the ability of leading a startup community. This master’s thesis examines literature on entrepreneurship, in particular Entrepreneurial Ecosystem (EE), to understand the role of leadership in sustaining a startup community. Although Stam’s (2015) EE framework recognizes that leadership enables entrepreneurship, it doesn’t define its characteristics and therefore, a more theoretical understanding is demanded. We have thus developed a conceptual framework that aims to facilitate empirical explorations and future analyses of the leadership dimension of Stam’s (2015) EE framework. Our conceptual framework of Entrepreneurial Leadership (EL) includes the following characteristics: collective and bottom-up approach, presence of formal and informal leaders, promotion of social proximity and mentorship driven leadership. The use of interviews as research method and our EL conceptual framework as analytical tool was useful to explore and understand the current state of EL in the startup communities of Amsterdam and Utrecht. On the one hand, the startup community of Amsterdam experiences a shared leadership where formal and informal leaders are recognized. Moreover, the strong presence of supporting organizations, networks of mentors and entrepreneurial events favour interaction among the stakeholders of the EE. On the other hand, Utrecht, a smaller and younger startup community, lacks success entrepreneurial stories that results in supporting organizations exercising the leadership role. Furthermore, there is a poor presence of entrepreneurial events and networks of entrepreneurs that lead to an unconnected community.
