Sijbrandij Foundation

The Sijbrandij Foundation is a philanthropic organization founded by Sid and Karen Sijbrandij. It supports promising, under-resourced approaches to transformational change, backing work that strengthens communities, advances research, and tackles systemic challenges. Rather than only funding ideas, the foundation also incubates projects, testing concepts and reducing execution risks before launching them as independent organizations.

Its initiatives span health, technology, philanthropy, education, and public art. Future of Cancer Care Today pilots ways to help patients organize information, understand treatment options, and work with care teams. The Data Center Energy project develops a model for solar-powered data centers. 100× Impact helps funders use pre-grant analysis and outcome-based decisions to improve philanthropic giving, while the GM Accelerator supports leaders exploring under-addressed social problems. The foundation also provides software engineering support to UNICEF’s Learning Passport, helping modernize and open-source its digital learning platform.

Through Big Art Loop in San Francisco and Artist in Residence Grand Bahama, the foundation supports public art and community revitalization.
