The researcher has investigated what factors influence a startup in an international public-private-partnership (PPP). The researcher has designed an exploratory study with a case study on Greenely, which is a Stockholm-based startup that has developed an application to monitor the household’s electricity consumption. The theoretical framework covers topics such as the diffusion of innovations (in particular eco-innovations in the form of smart meters in Europe), business models, the Business Model Canvas, and public-private-partnerships. The researcher conducted semistructured interviews with employees of the municipality of Cesena, Italy and with employees of Greenely, which is interested in expanding its offerings to Italy via partnerships. This study has shown that the factors that should influence a  tartup in an international PPP are, mainly, five: Funding, Language and cultural identity, Timeline, Common vision and Bureaucracy. The factors “Funding” and “Common vision”, in particular, influence the PPP the most.
