Mission & Focus Areas
The foundation says it takes calculated risks on early ideas where it can model a 100× social return and where early funding can help unlock capital to scale. Its stated areas of direct charitable activity include incentive design in education, health, and housing, and the Big Art Loop, a project to place temporary large-scale sculptures in public spaces around San Francisco.
Its grants support organizations working in areas including research, education, workforce development, immigration, land-use data, public art, and access to educational content. For example, Open Research Lab says it works on open-ended questions and long-term technology and research that should not be owned by a single company. Abundance Network Education says it seeks to improve California state and local government through research and education about public policy and government operations. The University of Chicago describes its mission as communicating and creating knowledge and fostering a community of scholars and students.
Grantmaking
In 2024, the foundation reported 16 grants totaling $5,435,593. Grants ranged from $18,000 to $1,500,000, with a median of $249,761.
