This current work is an example of applying the methodology of “thematic analysis” to a set of business success stories in the process of internationalization. It is assumed that these cases, as a hypothesis, constitute discourses obtained appropriately allowing synthesizing and relating some of the basic features inherent in the internationalization of companies. Results showed the prevalence of stimuli intrinsic to the company, to the detriment of extrinsic stimuli, and lower incidence that companies expose their barriers to internationalization. In the area of internationalization of firms, it confirms the association of entrepreneurial characteristics and the fundamental export nature of Portuguese business companies.
