Public Policy Institute of California

Public Policy Institute of California

The Public Policy Institute of California was established in 1994 by William R. Hewlett, Arjay Miller, and Roger W. Heyns. Hewlett provided the founding $70 million gift that seeded the endowment. The institute operates as a nonprofit research organization focused on California-specific issues. The endowment allocates across public equities, fixed income, private equity, and venture capital. Confirmed holdings include equity mutual funds valued at $144.1 million and alternative investments in private equity and hedge funds. Geographic exposure centers on the United States with secondary activity in global markets through fund commitments. Deployment occurs via direct holdings and limited partner positions rather than fund-of-funds structures. The organization employs 107 professionals across offices in San Francisco and Sacramento. It sold its former headquarters building at 500 Washington Street in late 2024. Adjacent vehicles include grant relationships with the James Irvine Foundation and the Bill & Melinda Gates Foundation for education and economic research. Governance separates the research mandate from endowment decisions through an independent board that includes Leon E. Panetta and Chet Hewitt. This structure limits direct family control after the initial Hewlett gift and channels capital exclusively toward policy research outputs.
