This paper focuses on the anxiety of digital entrepreneurs, or start-uppers, often portrayed as modern heroes. Nineteen clinical “life story” interviews were conducted by an anthropologist and a management researcher in a leading Parisian start-up incubator: NUMA. These exploratory results cannot be generalized and would require further research. They show that these young entrepreneurs, bound together by a strong cultural and economic capital and a paradoxical rejection of big corporations, build a collective identity by mimetic behavior marked by ambivalence between fear of failure and a major narcissistic investment in their project. They are subject to a creative anxiety that binds their commitment and willingness to change the world.
