The entrepreneurial support process in the space sector follows often the same development path starting with the ideation process, going to incubation, and then followed by acceleration and scale-up. While the sequence is clear, each step along this chain of entrepreneurship has its dynamic set of actors as well as key characteristics. For these reasons, there is not a single approach that would apply to all contexts to successfully launch a space business, but one element is clear: the ideation phase is critical because this is where the new concepts emerge.
