PurposeThis study aims to explore how aspiring entrepreneurs navigate between their own individual self-concept and the organisational identity of the new venture during the process of new venture creation.Design/methodology/approachThe study draws on three cases of aspiring entrepreneurs within a UK-based university incubator in the process of “becoming” entrepreneurs. Semi-structured interviews and secondary data were collected and analysed using a flexible pattern matching approach.FindingsThe data illustrated parallel identity and sensemaking processes occurring as the aspiring entrepreneurs navigated towards new venture formation. For the organisational identity process, three key stages were found to occur: referent identity labelling, projection and identity reification. Concurrently the sensemaking process made up of creation, interpretation and enactment were seen to enable identity transitioning mechanisms: cue identification, liminal sensegiving and recognition of formal venture boundaries, which led to the organisational identity being formed.Research limitations/implicationsThis study is exploratory in nature thus future research is required to clarify the relationship between identity work practices and the process of creating a new venture (Oliver and Vough, 2020). The paper is limited to successful instances of new venture formation, and though this helped to extricate the identity transitioning stages and mechanisms that have thus far remained implicit within the process of new venture creation, it could be extended to examine entrepreneurs who fail to set up new ventures. This limitation opens avenues for further research on identity formation in failed ventures (Snihur and Clarysse, 2022) and on how entrepreneurs negotiate contested identities (Varlander et al., 2020). Furthermore, entrepreneurs take different pathways to new venture formation (Shepherd et al., 2021) and while this study follows the journey of aspiring entrepreneurs who differed in terms of sector, education and prior entrepreneurial experience (Shane, 2003), future researchers could undertake a more in-depth ethnographic study including the effects of incubator setting and how these can be best supported, as this was outside the original remit of this study. Given the importance of the university incubator (Bergman and McMullen, 2022), its role in the construction of new venture identity is an interesting area for future research.Practical implicationsThis study provides a practical contribution into entrepreneurship curricula and incubator training, emphasising the importance of understanding the relevance of the entrepreneur's self-concept in making sense of future venture identities. Through the findings of this study, the importance of cue identification and how aspiring entrepreneurs rely on these to carve out the identity of their budding venture is demonstrated. Incubator spaces may have a role to play in supporting aspiring entrepreneurs to reflect on and interpret feedback (liminal sensegiving) during the venture creation process. Furthermore, both educators and incubator managers need to be aware of the state of in-between-ness aspiring entrepreneurs will face as they carve out the identity of the budding venture. This study enables educators to advise aspiring entrepreneurs that there will come a point on the entrepreneurial journey when they need to emphasise boundary setting between self and organisation to enable organisational identity to be fostered and venture formation realised. This study advises incubator managers to consider whether support around business registrations and creation of business accounts should be provided earlier in the incubation programme to emphasise boundary setting between self and organisation. There is a fruitful avenue for future research to extend the work in this paper to fully understand how this might be taught and practiced in the classrooms.Originality/valueBy extricating the stages of organisational identity formation, often hidden within the new venture creation process, this study has framed new venture creation as a liminal experience and a visible site of identity work. This study presents a process model of the key identity transitioning stages and mechanisms in new ventures, by illustrating how aspiring entrepreneurs' sensemaking influences identity transitions during the process of venture creation.
