Purpose This paper aims to explore how entrepreneurs use social media (SM) to develop their organisational identity within business networks. Design/methodology/approach A single embedded case study was used comprising a case firm entrepreneur and eight connected network actors within an artisan food context in Ireland. Data was collected using an in-depth interview complemented with content analysis of networked firms’ Facebook posts (N = 1,652) over a three-year period. Findings This paper identifies four common network processes through which entrepreneurs can leverage SM to develop their organisational identity within networks. The processes are network relating, collaborating within networks, interacting with trends and connecting with community. Research limitations/implications Findings are limited to the Irish artisan food sector and explore identity development through a single SM platform. The applicability and variation of use of the processes across industries would serve to further refine the processes identified. Practical implications Practically, the four processes through which identity within a network can be developed using SM can help entrepreneurs to access and position themselves within business networks, gain access to resources and overcome the classic limitations of newness and smallness. Originality/value This paper provides a conceptual framework illustrating the processes involved in developing entrepreneurial organisational identity within business networks using SM. This paper adds to a growing literature that places interaction at the heart of identity development and responds to calls to further understanding of the process of identity development for entrepreneurial ventures.
