The way for banks to get started is to capture, structure, and centrally process data about their customers. To achieve this, several challenges need to be overcome, such as breaking down organisational silos that hinder consistent data usage. What’s more, the technical effort should not be underestimated, especially when it comes to tracking customer interests. Since this approach only works with the consent of customers, the offerings must also be designed to be highly trustworthy and, above all, provide tangible added value for the users.
