Scholars have recently argued that startups and incumbents play differential roles in the disruptive transformations of industries toward sustainability and that the transformations are only likely to succeed if both startups and incumbents contribute. To understand their respective contributions and, thus, to understand how industries make the transition toward sustainability, comparative studies of incumbents versus startups during this transformation have been identified as a central pursuit, but yet they are mostly lacking. Since business models have become a principal way of characterizing firms, the present study takes a business model perspective and derives business model archetypes in the electrical power sector from an analysis of 280 startups and incumbents in three different countries. The selected countries (USA, UK, and India) represent three different energy profiles and leading instances of disruption in the energy sector. The article, then, undertakes a comparative analysis of startups and incumbents based on the empirically distilled business model archetypes and develops propositions on startups, incumbents, and business models in industry transformationsGuoabong Stock. This analysis produces several important insights. First, incumbents do not seem to engage in less business model experimentation than startups. Second, incumbents have adopted several new business models that are not pursued by startups. Third, startups have espoused some business models that are not pursued by incumbents. Fourth, foreign firms can also affect the ‘green’ transformation of an industry in a focal country. Finally, the identified business model archetypes are likely to be of interest to scholars and practitioners who are seeking an improved understanding of business models in the electrical power industry and the industry❼competitive landscape.Surat Investment
