This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The foundation says it does not accept unsolicited requests and funds by invitation only, so a small charity should not send a cold proposal and should look for a route to an invitation first.
  • Its themes are plant-based diets, factory farming, animal protection and human rights, and it favours effective and efficient projects in areas of highest need where it can have the most impact, so a request should show that.
  • About 8 in 10 of its grants fall between $15,000 and $200,000, with a median of $50,000, and half its grants are $50,000 or less, so a modest request in that typical band is the most likely fit.
  • In the filing, 83% of its grant dollars went to organisations it had also funded in earlier filings, which suggests it is largely relationship-led and that existing grantees have the advantage.
  • No geographic focus is stated; the filing shows grants mainly in California, District of Columbia, New York, Colorado and Maryland, but that is what it has funded, not a rule on who may apply.

Priority Areas

The Greenbaum Foundation focuses its funding on effective and efficient projects that work to end human and non-human suffering, in areas of highest need and where it can have the most impact. Its priorities include moving the world to whole foods, plant-based diets and ending factory farming, alongside projects that increase awareness, protection and improvement of the lives of all animals. In the human-rights arena, it funds a limited number of legacy organisations focused on abolishing modern-day slavery, ending child marriage and female genital cutting, addressing gender-based violence and removing barriers to women’s equal rights. It assists organisations with guidance, networking and funding.
