Abstract
The goal of the paper is to identify the importance and role of social capital accumulated in companies and state diplomacy for companies’ internationalization. The research aims to show the relations between the actors, to contribute to the discourse between the actors, to suggest possible improvements, and thus to contribute to the success in the internationalization of companies. The research approach is interdisciplinary. The paper offers not only a theoretical review and reflection but also new findings resulting from the concretization of the topic based on an inductive approach—the case of the Republic of Slovenia. The research has shown that the most important mechanisms for entering the market were product quality, brand, and personal acquaintances. The results of the interviews showed the importance of personal acquaintances, combined with the implicit knowledge, owned by the employees of the national institutions.
