8. Conclusion
This exploratory study uses deductive and inductive knowledge generation approaches to identify go-to-market strategies and their elements for EIs launched by start-ups. Furthermore, this study analyzes start-ups' underlying intentions for employing specific go-to-market strategy elements and discloses the elements' signaling functions.
Data triangulation using multiple collection methods ensures the greatest generalizability possible for the results garnered with the applied empirical approach. In doing so, the resulting insights contribute to the innovation literature and to the understanding of the launch of EIs by start-ups.
First, this study extends the 7P framework (Booms & Bitner, 1981) to the specific context of start-up EIs. The results illustrate that the design of the 7Ps has to adapt to the financial reality of start-ups and the digital nature of EIs. Second, this study theoretically contributes to signaling theory by deriving an understanding of the signaling functions of EI go-to-market strategy elements, extending signaling theory to the context of start-ups and their EIs, and discovering two particular types of signals: trustworthiness and usability signals. Third, this study contributes to the understanding of the adoption process of EIs by revealing factors that drive EI adoption. Based on a historical method analysis and expert interviews, this study proposes a mediating mechanism between go-to-market strategies for EIs and EI adoption, that is, increasing trust in EIs through trustworthiness signals sent by start-ups. Furthermore, this study proposes a moderating mechanism on the negative influence of the uncertainty associated with start-ups and their EIs on EI adoption, that is, reducing the negative impact of this uncertainty on EI adoption via usability signals. Hence, the findings allow us to derive several propositions regarding the influence of EI go-tomarket strategies and their signaling functions on potential customers' trust and uncertainty and, ultimately, on EI adoption. These propositions identify several aspects that can spur further research on go-tomarket strategies for EIs. Finally, this study contributes to the innovation launch practice by presenting managerial implications for start-ups launching EIs.
