In this paper, we argue that imperfections in entrepreneurial process may also be a question of point of view. Scale-up is openly acknowledged as a difficult phase of development, even more so when it comes to deeptech start-ups for which development mechanisms are not yet fully understood. We challenge the definition of a deeptech scale-up as simple replication of a validated business model. We conducted an intervention-research in two deeptech start-ups. Firstly, the study of their scale-up strategy highlights the continuity of explorations. Secondly, we use a design approach to carry out explorations from the constituted creative heritage.
