Refugee integration is one of the global challenges of the present, a time when the corporate sector is regarded as a key actor in multi-stakeholder partnerships through the 2030 Agenda for Sustainable Development. In this paper I examine the role of the corporate sector as a partner of the state in addressing the movement of a large number of refugees into Germany in 2015 and after. Based on interview data and informal conversations collected between 2017 to 2020 with members of Wir Zusammen, an integration initiative of the corporate sector, supplemented by a review of relevant business reports and media documentation, I discuss the multi-facetted engagements by parts of the corporate sector in Germany with refugee integration. The various types of corporate engagement are analysed as 'thin' and 'thick', and as following different institutional logics. With this, the paper adds to our understanding of the political dimensions of corporate responses, their potential to challenge the status quo, and their pitfalls. Ultimately, the paper argues that corporate engagement with humanitarian and development challenges, here focused on refugee integration, works best when embedded locally and context specific.
