The main problem involved here is the proposition of a data-driven segmentation approach in the prevention of the loss of remunerative customers’ acquisition in the digital era’s banking industry. The reason for choosing Kohonen Network is the ability to work on large volumes of data and the most appropriate determination of the cluster number, which is the most important decision for cluster analysis, by the technique itself. The well-known purpose of cluster analysis in business analytics is to provide the necessary foresight by revealing previously unknown critical customer characteristics and degrees of importance in order to assist the business in charge in strategic marketing decisions such as market segmentation and target market selection. As a result of the study, new marketing strategies regarding the loss of new customers’ acquisition suggested through the findings of Kohonen clusters.
