In response to the escalating challenges facing our societies, sustainable entrepreneurship emerges as a promising yet delicately balanced solution. This thesis delves into the hybrid model of sustainable entrepreneurship, which integrates social and environmental missions with economic activities, through the study of logics and motivations of ecotourism entrepreneurs in southern Benin. Our qualitative approaches reveal the dynamics of excessive commitment to societal missions and explore the interplay between social and environmental motivations and demotivations. The inherent tensions associated with hybridity have led the Beninese entrepreneurs to adopt community-based and spiritual approaches unique to their context. This research advances our understanding of the underlying mechanisms that define hybridity in sustainable entrepreneurship.
