Rather than limiting themselves to acting as mere financial intermediaries of corporate philanthropic funds, corporate foundations (CFs) may contribute to the achievement of the Sustainable Development Goals (SDGs) as partnership brokers. Based on the literature on the SDGs, cross-sector partnerships, the influence of the private sector on the SDGs, and institutional philanthropic involvement in the SDGs, this paper shows how the unique characteristics of CFs and their position between the business sector and civil society make them ideal partnership brokers in cross-sector collaborations. Furthermore, this study examines how CFs approach the Agenda 2030 with respect to their activities and strategies. Following an explorative research approach, data were collected through an online survey among CF managers in Switzerland, Liechtenstein, and Germany. The findings suggest that, in order to contribute more effectively to the SDGs, CFs should make more and better use of their capacities in bridging institutional logics, pooling resources, and initiating partnerships between different sectors.
