The purpose of this study is to explore the origins of organizational configurations. Configurations are “multidimensional constellations of conceptually distinct characteristics that commonly occur together” (Meyer et al., 1993) and consist of core and peripheral elements that consistently or inconsistently interact with each other (Siggelkow, 2002). Scholars have typically investigated types and implications of such constellations in the context of established firms. The literature on how new configurations emerge is much less developed. Specifically, we know little about how new ventures create their business architecture although it insinuates consequences for further venture development supporting some future avenues while restricting others. By following the creation of new ventures we seek to develop a better understanding of the underlying interactions and processes of configurational elements and their emergence. We argue that this is an important topic, because the decisions new ventures have made in the past may considerably influence their development and performance in the future.
