Over half of businesses are started by people who are already employed, a phenomenon called hybrid entrepreneurship (HE). Although research on hybrid entrepreneurship has increased in recent years, the diversity of perspectives has led to a fragmented literature that makes it difficult to advance our understanding of this phenomenon. We fill this gap by conducting an inclusive systematic review of research conducted on hybrid entrepreneurship. Our review integrates existing research in a framework of antecedents and outcomes of hybrid entrepreneurship. This enables us to propose opportunities for future research to contribute to areas that have been overlooked. In doing so, we contribute to the emerging literature on hybrid entrepreneurship.
