The content of this book presents research that sought to identify the reasons that lead employees of intrapreneurial companies to create their own businesses. A field study was carried out in which five former employees of a company considered to be intrapreneurial were interviewed, all of whom had left the organization in order to set up their own businesses. The data obtained in the field research allowed us to formulate hypotheses that indicate, above all, a certain common conception among the subjects interviewed about the figure of the entrepreneur. This conception then appears as a possible explanatory nucleus for the reasons why these individuals preferred the risks of entrepreneurship to the relative stability of intrapreneurship.
