In the literature of international entrepreneurship, there is a large number of researches and writings related to the study of the speed of internationalization at young age of the company, using different names, such as International New Ventures (INV), Born Global (BG), or Fast and Early Internationalization Companies (EIRP). All these studies concern SMEs of mature industrialized countries in the European Union, or in the United States. And explain this orientation to internationalization at an early age since childhood especially by the saturation and the strong rivalry within the internal market. However, EIRPs also exist in less industrialized countries such as Morocco. In this paper other factors explaining the rapid internationalization of Moroccan SMEs in the agric-food sector have been explored. These are essentially cultural determinants, in addition to the specific characteristics of the manager, the industry, and the business environment in the Moroccan context.
