The literature of the scientific written work about start-up success, entrepreneurial work motivation and burnout symptoms has its main focus on start-up owners, their motivation and stress factors as well as the possible resulting burnout symptoms. Furthermore, the main goal of the master thesis is to analyze the question, if correlations do exist among start-up success, entrepreneurial motivation and burnout symptoms and how they are influenced by each other. In order to find a suitable data, questionnaires were elaborated. Based on these predefined questions, computer-assisted telephone interviews were conducted with new Austrian start-up founders. According to the study, the results not only exhibit correlations between start-up success and burnout symptoms but also between start-up success and entrepreneurial work motivation. The meaning of this statement resides in the facts that the more start-up success will be generated by entrepreneurs, the less burnout symptoms will occur. Additionally, the more startup success will be created, the more motivated entrepreneurs will be and therefore, will approach certain corporate tasks.
