Skyline Foundation

What Skyline Foundation does

Skyline Foundation is a private philanthropic foundation established in 2000 by Yahoo! co-founders Angela and David Filo, operating from an endowment generated by their internet company wealth. The foundation practices trust-based philanthropy, distributing multi-year, flexible general operating support to nonprofit organizations across four programmatic areas: Climate Solutions, Just Democracy, Equity in Education, and Birth Justice. Grants are made by invitation only, with the foundation identifying partner organizations through research, relationships, and referrals rather than open RFPs.

In 2025 alone, Skyline deployed $101 million across 207 grantees, bringing cumulative giving to $502 million across 330+ organizations since inception. The foundation is staffed by approximately 13 people based in the San Francisco Bay Area, led by Executive Director Angie Chen and four program leads with deep domain credentials spanning policy, organizing, and academic expertise. Recent grantmaking shows anchor commitments in the $3M-$8M range to organizations such as GiveDirectly, NRDC, Energy Foundation, and Fines and Fees Justice Center, alongside a growing slate of climate tech intermediaries including Third Derivative (RMI) and LabStart Innovations.

The foundation's revenue model is endowment-driven: the corpus is screened to exclude industries causing environmental and social harm, with a growing share of assets directly invested in funds and companies aligned with its values and programs. Operational support is provided by Pacific Foundation Services. Skyline does not sell products or services, does not generate revenue from operations in a commercial sense, and does not have customers in the traditional sense — its "clients" are mission-aligned nonprofit grantees selected through relationship-driven curation rather than market competition.
