The banking industry has been experiencing radical change for the last years (Wingard, n.d.). Due to digitalisation a new type of user has arisen. This user is characterised by always being connected while operating on multiple devices. This segment likes to be informed and expects answers, immediacy and transparency. They compare options before making important decisions and they are demanding with the companies they interact with (Rowe, 2019). To operate in this environment, where customers demand proximity, quality and transparency, Banc Sabadell has summarised its strengths in the following strategy “Estar donde estés” (To be where you are). This strategy aims to create a user-centered mindset, creating excellent services that show social responsibility and transparency. All of that will result in a long-term relationship with its customers (Quienes Somos, 2015). Banc Sabadell, with 135 years of history, is one of the largest banking groups in Spain, with international presence (Quienes Somos, 2015). For Banc Sabadell, mortgage loans are one of the products that generate the greatest customer loyalty and commercial margin. And for its customers, buying a house is one of the biggest milestones in their lives. This project is born from the gap identified in which the strategy of Banc Sabadell is not sufficiently perceived in the home buying process. In general, the process of buying a house or getting information about the different steps is most of the time a hassle for the users (Parrin, 2019). This project aims to provide a tangible strategy for Banc Sabadell to increase customer engagement while offering a smooth and remarkable home buying process. Through user research, this project explores the user needs, behaviours and expectations throughout the home buying process. A need is identified to offer a smooth and socially engaging home buying process to young adults which allows them and their relatives to feel reassured and experience the process together. As a result, Doyle is borned. Doyle is a mobile service application that offers adults independence in the purchasing process through providing the tools and information that users need. As part of this strategy, other three elements that play an important role are also proposed.
