Smart city is an entrepreneurial city. There is a bidirectional relationship between entrepreneurship and smart cities. First, entrepreneurs initiate technological interventions that help cities undergo socio-technical transitions and become smart cities. Second, the technologies being adopted in cities generate data which then helps enterprises to explore new opportunities. Despite the potential of this bidirectional relationship, this connection has been less explored. In order to fill the gap, this paper reviews the extant literature in the field to contextualize the role that entrepreneurship plays in building smart cities and how smart cities influence entrepreneurial business models. I referred to 479 papers published until June 2017 on smart cities and 35 papers out of those related to entrepreneurship using the method of clustered content analysis. This article contributes towards increasing our understanding of this bidirectional relationship, and opens up research avenues for future research in the fields of smart cities and entrepreneurship.
