The global market nowadays demands even more strongly that companies should seek new sources of knowledge and develop new skills in order to become more innovative. In this context, it is clear that those companies that are more deeply involved with the international market develop more innovative types of technological capability than those which operate in the domestic market only. Thus, this paper aims to identify the similarities and/or differences in the technological capabilities of software companies in Curitiba, the capital of the state of Paraná in Brazil, with different levels of internationalization. From the case studies, a direct relationship was observed between increased international involvement and an increase in accumulated technological capabilities.
