This article is about how SMEs reduce their liability of network outsidership in the process of establishing a network insider position in foreign business networks. By examining how SMEs establish insidership positions in institutionally different business networks, the authors contributes to the network approach to firm internationalization. From a detailed longitudinal and retrospective case study of four SMEs from mature market entering emerging country markets and four SMEs from such immature markets entering mature markets, the authors develop propositions based on intra-group and inter-group analysis. The propositions concern the parties to which the exporter initiates and develops relationships when plugging into the foreign network (the entry node), and how the firm reaches an insider position in this network (the entry process). Three distinct network types are identified along this entry process: the exposure network, the formation network and the sustenance network.
