The theories of internationalization explain how firms develop their processes for exporting products and services, and how the impact of network relations invigorates them towards overcoming some constraints. For this reason, this paper aims at putting network relations into international market entry modes. As a result of exploring three case studies of Colombian companies, we briefly describe the strategies and factors that sped up the process, and how the consolidation of social and business relations impacts their internationalization. In this way, the perspective to the internationalization of the SME Gastro Innova can be raised as a high-level entry mode when analyzed from the network theory. Three theoretical perspectives of internationalization that will serve the purpose of supporting the analysis of the growth of a company at the international level are considered. First, topics such as types of strategies and key factors for internationalization are addressed; after that, some current international treaties that collaborate in the strengthening of macroeconomic relations are mentioned; and finally, the impact of network relations for the internationalization of SMEs is discussed.
