Funding pattern

What this funder pays for, at what size, and how to position adjacent work. Read from their filings, with every number checked against the record.

Where the money goes

  • Global climate mitigation, industrial decarbonization, clean energy policy
  • US democracy, election trust, civic institutions, racial justice groups
  • Gender justice, reproductive health, feminist economies in Africa
  • Education: teaching and learning, community schools, civic education
  • Western US conservation, rivers, wildfire, water policy
  • Economic policy reimagining and evidence-informed governance

Typical grant

Median grant is $150,000 with the middle half between $50,000 and $300,000, so most of the portfolio is modest even though the totals are enormous. The eight-figure checks go to intermediaries and pooled funds they helped build, ClimateWorks, European Climate Foundation, Energy Foundation, New Venture Fund, and those repeat annually. Multi-year and repeat giving is the norm; the same names recur across 2022 to 2024.

Their words

Phrases from their own grant descriptions, worth speaking back to them.

  • “FOR GENERAL OPERATING SUPPORT”
  • “POOLED FUND”
  • “DECARBONIZATION”
  • “GENDER-JUST”
  • “EVIDENCE AND EQUITY”

Positioning adjacent work

  • Anchor to a named theme they already fund: industrial decarbonization, election trust, community schools, or gender-just economies.
  • Ask in the $150,000 to $300,000 band for a first grant; seven figures goes to established intermediaries.
  • Request general operating support rather than project funding; it is their dominant phrasing.
  • If work is international, tie it to Africa, China, or Latin America, where their non-US grants concentrate.

Worth knowing: California and DC recipients take the bulk of the money, and a small set of intermediaries (ClimateWorks, European Climate Foundation, New Venture Fund, Rockefeller Philanthropy Advisors, Windward Fund) absorb the largest checks by fiscal sponsoring pooled funds. Getting into one of those pooled vehicles is often a more realistic path than a direct grant, and the giving pattern reads as long relationships rather than fresh entrants.
