Arcus Foundation
At a glance
Key takeaways
- If your work advances LGBTQ social justice or the conservation of great apes and gibbons, the foundation's stated focus fits, though no geographic focus is stated, so its grants across the United States, the United Kingdom and elsewhere do not by themselves rule out your location.
- About 8 in 10 of its grants to organisations fall between $300 and $175,000, with a median of about $68,500, so a request near that figure is typical, not a ceiling, given that its largest grant was about $1,450,000.
- Repeat giving is strong: 85% of its grant dollars to organisations in the filing went to organisations it had also funded in an earlier filing, so approaching it cold is possible but most of its money goes to existing grantees.
- For the Great Apes & Gibbons Program, begin with an Initial Funding Concept submitted online; for Social Justice, you may submit an Initial Funding Concept online or a Letter of Inquiry directly to an Arcus staff member, and invitations to a Letter of Inquiry or full proposal follow review.
- The filing gives no deadlines, and only an organisation without an equal employment opportunity policy that separately includes sexual orientation and gender identity as protected categories should hold back, since the foundation requires that policy.
