The emphasis on corporate-startup collaboration has reached a new level in the context of digital transformation of most industries. Co-creation, as one non-equity based model for corporate-startup collaboration is increasingly getting attention among corporations and startups, but also among local governments. However, even if companies, governments, and startups invest in this approach for innovation and societal change, the concept is under-researched. The purpose of this paper is to further examine corporate-startup co-creation by conducting a systematic literature review, as well as present a real case ‘FirstBuild’. The findings were that co-creation as a corporate-startup collaboration model increases in attention. However, there is currently a large knowledge gap in previous research in regards to this phenomenon and more research on corporate-startup co-creation is needed, specifically in regards to metrics and its effects on corporate innovation, startups’ growth, and society.
