Past research shows that most of the Fintech industry players are either big corporate banks or technological companies which have started their main business model on FinTech. However, it seems that many other businesses in digital ecosystem avoid entering this field as a new entrant. On the current research we started the study with an in-depth literature review to recognize the main clusters of current academic research on Fintech, which its result is shared below. On the next step, we plan to have some interviews with FinTech experts to list the challenges on each of the identified clusters. Finally, we will approach the digital businesses to share their perception on those challenges through a Fuzzy DEMATEL approach. The output will be (1) ranking of the main challenges and (2) the cause-and-effect relationship between those challenges. These outputs can be used for policy development in reducing the above-mentioned barriers and challenges.
