The importance of clean-tech ventures lies in their mission to protect the environment by facilitating the increased use of clean energy and environmentally friendly solutions. At the same time, the entrepreneurial nature of many of these firms enables introduction of radical innovations necessary for making breakthroughs in the industries of renewable energy and environmental technologies. This study’s purpose is threefold. First, we review the existing research on clean-tech ventures published in major business, management and entrepreneurship journals. Second, we revise the literature on the performance determinants of new technology-based firms (NTBFs) and reflect on its applicability to the context of clean technology. Third, we identify future research directions to further develop this emerging research stream. Thus, our work contributes to multidisciplinary and highly relevant topic by collating different bodies of literature that could shed light on the important determinants of clean-tech venture performance and providing future research agenda.
