The competition and the collaboration of established banks and challenging fintechs are expected to dramatically change the future financial services business ecosystem. An ecosystem’s ability to attract new firms and to continuously evolve is of strategic importance for incumbent companies as well as for those who decide to join the ecosystem. In our study, we analyzed the business models of 286 international fintechs and banks. Based on this analysis, we present seven types of business models in which fintechs and banks collaborate. With these types, we contribute to research on fintechs by providing novel insights on how the ecosystem moves from competition among banks towards coopeti-tion between banks and fintechs.
