Transnational entrepreneurship studies highlight the importance of personal profiles, institutions, and networks in creating and succeeding in this type of entrepreneurship. Even so, less is known about migrants whose networks are fragmented and closed, facing challenging environments at home and abroad. This paper aims to study the attributes of transnational entrepreneurs with small and fragmented networks, from post-conflict environments, who can perform an important role in the socioeconomic development and internationalization level of their countries of origin due to the cross border mobilization of resources they encourage. For that reason, the specific case of Colombian transnational entrepreneurs who have been able to overcome those obstacles with their transnational business is analyzed with the intention of understanding how they manage those shortcomings when engaging in transnational entrepreneurship. In aiming to obtain a deeper understanding of their characteristics, similitudes, differences, and motivations, the research uses multiple case studies. The main findings suggest that transnational entrepreneurs form purposeful-strategic networks to compensate their lack of amalgamated social systems, and that they have special qualities that distinguish them from other Colombian migrants and transnational entrepreneurs. Moreover, Colombian transnational entrepreneurs focus their business in the international market, using strategically their knowledge of both the local and foreign environment, while their main interest to do so is not altruistic but business oriented. Governments from post-conflict countries should promote transnational entrepreneurship while facilitating network formation and institutional trust through diverse strategies. Finally, implications for further research are drawn.

Purpose The purpose of this paper is to analyze the characteristics of Colombian migrants’ transnational businesses (TBs) and their operations. To this end, the characteristics of the entrepreneurs, their businesses and the patterns of their international operations are discussed and compared. Design/methodology/approach The paper analyses 14 cases developed from data from in-depth interviews with the same number of Colombian entrepreneurs who migrated to the USA. Similarly, the analysis includes secondary data sources. Findings TBs created by Colombian transnational entrepreneurs (TEs) aim to be successful through the best use of the resources of each market, allowing them to produce with lower costs and better quality in their country of origin while selling in more developed countries, such as the USA (their country of destination). The operations of those businesses are limited by their financial resources, small and fragmented networks, and their organic growth. The personal characteristics of the TE and their business comprise a nexus that helps to overcome business shortcomings. Originality/value The paper contributes to entrepreneurship, migration and international business literature by illuminating the nexus between the personal characteristics of the TE and the unique characteristics of their business, including the analysis of their international operations. Likewise, considering the characteristics of the context under study, the paper presents findings that are interesting for countries with similar social and economic difficulties.
