This study presents the relevant factors which allowed some companies from the Timis county, a Western region of Romania, to grow fast before and after 2008. We are considering that fast growing companies, defined in this paper, have an important contribution to regional development, especially by creating value and offering new jobs. Our researches done in the last years on fast growing companies from the Western region of Romania, allow us to identify the characteristics of these companies, as well as their best practices, and to set them as examples for companies which want and can grow. The factors which favored the fast growing of these companies are directly related to the entrepreneur-manager (motivations, qualities, skills), management and managerial team, external environment and the managers’ interaction, processes, technology and products and existent leadership – all these, within a period of 3 to 4 years. The companies’ growth processes were analyzed based on the Gibb A. model.
