Abstract
In this chapter the concept of the difference between a technological start-up and a complete firm is introduced. The discussion explains the characteristics of the technological start-up (TSU) and the reasons these have developed as part of a strategic fit of the TSU to its specific tasks and environment. The discussion relates that the characteristics of the TSU, structure, culture, and activities have an impact on management capabilities and their development. The discussion along these three aspects also denotes the literature in the field in support of the claims made. However, the discussion is not entirely theoretical but includes also references to practical aspects.
