In the digital era, the question of however the role of traditional relationship marketing methods is still relevant in the landscape of business-to-business (B2B) interactions. This thesis highlights the gap of understanding how traditional and digital relationship marketing coexist within a B2B context. While the magnitude of literature has primarily focused on business-to-consumer marketing, the B2B area remains unexplored in comparison to its economic significance. This thesis therefore aims to contribute to the literature by investigating how traditional and digital relationship marketing coexists for building and maintaining relationships that have a positive impact on business development. To address our purpose, we have conducted a qualitative study, using semi- structed interviews, an inductive approach and exploratory research design, investigates the coexistence of traditional and digital relationship marketing within a B2B context. Further aiming to clarify their roles in fostering business development and network establishment. We collected primary data from six local businesses embedded in B2B networks to help us answer our research question How does traditional and digital relationship marketing coexist? Based on a combination of historical perspective, theoretical framework, and empirical data, this thesis finds that both methods are essential for fostering successful relationships. With traditional methods, like face-to-face (F2F) interactions building trust and commitment, while digital tools facilitate efficient communication and global reach. The thesis conclude that the coexistence of traditional and digital methods allows firms to balance relationship depth and efficiency, driving mutual value and sustainable growth in dynamic business environments.
