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

Democracy protection, election integrity, civic participation in Washington, DC
Boston-area community nonprofits, health centers, youth services capital projects
Biomedical and mental health research, Broad Institute and Israeli science
Arab Israeli economic advancement, employment, and shared society work
Climate philanthropy through large intermediaries and corporate engagement
Jewish communal life in Greater Boston and Israel

Typical grant

Median grant is $100,000, with the middle half running $25,000 to $250,000. The seven-figure checks go to national democracy and climate intermediaries (Election Trust Initiative, ClimateWorks, New Venture Fund) and to the Broad Institute for scientific research; the $250,000 to $500,000 band is dominated by Boston capital projects and local operating support. With 916 grants to 444 recipients over three years, roughly two grants per organization, repeat giving is the norm rather than the exception.

Their words

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

“Unrestricted operating support”
“Capital project support”
“Support for scientific research”
“Support for civic participation”
“Support for work to advance Arab society”

Positioning adjacent work

Tie research to their named science bets: Broad Institute, Human Cell Atlas, Israel Science Foundation IPMP and MAVRI grants.
Ask $200,000 to $500,000 for a first research grant; seven figures goes to established intermediaries only.
If Boston-based, frame a capital or infrastructure need; they wrote many $250,000 to $500,000 capital checks in 2024.
Emphasize willingness to take unrestricted operating support; they fund general operations more readily than most science funders.

Worth knowing: Massachusetts takes 550 of 916 grants and Washington, DC another 80, so the portfolio is a Boston community program plus a national democracy program bolted together. A meaningful share of dollars flows to Israel and Israeli institutions, especially Arab Israeli economic inclusion, and the largest checks go to fiscal sponsors and pooled funds like New Venture Fund, Hopewell Fund, and ClimateWorks rather than to direct applicants.
