Scaling has become a dominant topic in the startup ecosystem and political landscape, as evidenced by the development of scale-up-focused news, forums, databases, and public interventions, such as public venture capital programmes. Even though existing bottlenecks in scaling are known, the literature lacks concrete guidance on how to navigate a scale-up journey from an entrepreneur's perspective, let alone how to do it sustainably. Based on available research, workshops and interviews with experts, this paper addresses this shortcoming by developing two artefacts: (1) the Venture ESG model that takes environmental, social and governance aspects into account, and (2) the Scale-up Navigator framework. The results provide guidance to both stakeholders of scaling ventures and entrepreneurship researchers on which ESG variables exist that might impact the scaling process of ventures today and in the future (model 1). They also highlight relevant issues during a venture's scale-up journey and how to address these efficiently and sustainably (model 2). Thus, this paper contributes significantly to the field of entrepreneurship research while providing practical guidance to practitioners.
