This survey presents an analysis of activity patterns of business being created, which are studied through multiple interviews and narrative syntheses. The qualitative analysis of the accumuated stories shows that we can distinguish balance between activities and projects that differ depending on whether the companies are in a project phase, an exploration phase, a stabilization phase in a market, a crisis phas or a survival phase. Coding sequences on the basis of periods of one year allows systematic analysis and the construction of a typology of trajectories.
