The purpose of this paper is to analyse customer experience (CX) in the fintech sector. Fintech is a dynamic and innovative field that fully benefits from advances in information and communication technology. The concept of customer experience is multidimensional, analysed from various perspectives, and with distinct valences in different industries. Based on the stimulus-organism-response (S-O-R) approach, we proposed a model in which customer experience in fintech is the result of customer’s evaluation of the stimuli proposed by fintech companies. Using partial least squares equation modelling (PLS-SEM), we tested a series of hypotheses and validated the proposed model. The results showed that perceived value, customer support, assurance, speed and perceived firm innovativeness are positively related to customer experience in fintech. In turn, customer experience is positively associated with loyalty intentions of the customer. Our paper contributes in identifying the dimensions, the determinants and the outcomes of customer experience in fintech, while from a managerial perspective, we demonstrate how fintech companies must integrate customer experience in their business models.
