Internationalization is a complex process in which companies search for and exploit new opportunities in foreign markets. Although internationalization can be very lucrative, it can also pose various risks to companies, which are multiplied in the volatile, uncertain, complex, and ambiguous (VUCA) business environment. This study focuses on the influence of network relationships on internationalization failure among Estonian companies. Based on our qualitative study in three SMEs, we found that inefficient networking can increase companies’ risks, lead to a lack of information, and to wrong decisions as well as prevent them from finding good partners. Our findings suggest that companies are significantly dependent on their network, particularly on the information flows to which they have access via their network. The networks are also important enablers of internationalization, and an appropriate and effective network can prevent companies from failing.
