The purpose with this article is to review models used to describe and explain the establishment and development of international new ventures in order to investigate how and why international new ventures are established and developed. This article attempts an integration of extant theory on International Entrepreneurship, and specifically but not exclusively, International New Ventures (INVs). The three resulting ‘meta-models’ depict the activities and loci of such firms, the motivating factors that give rise to such firms and their growth modalities and strategies. These models reflect the merger of entrepreneurship and international business into the field of international entrepreneurship.
