This paper investigates determinants of engagement in various stages of the entrepreneurial process while considering an individual's start-up motivation using 2007 survey data for 27 European
countries and the US. Next to opportunity and necessity start-up motivations, we take into account individuals driven by a combination of both motivations. We observe that opportunity- and necessitydriven entrepreneurs as well as those with mixed start-up motivations have different profiles. Furthermore, they differ concerning the factors that inspire or hinder them to engage in the entrepreneurial process more fully ('to climb the entrepreneurial ladder'). For example, entrepreneurship-specific education, selfemployed parents, risk tolerance, perception of lack of financial support, and living in a metropolitan area are important variables in determining entrepreneurial engagement and failure for opportunity-driven individuals, but they are not (or less) important for necessity-driven individuals.
