Overview

Founded in 1994 by philanthropy veteran Meg Gage, Proteus Fund has evolved into a $51-60 million philanthropic organization that connects progressive funders with grassroots movements for social justice. With over 90 staff members operating across 27 states, Proteus has distributed more than $297 million through over 6,000 grants to support activists, advocates, networks, and organizations working at local, state, and national levels. The organization operates through three primary models: donor collaboratives that pool philanthropic resources around pressing issues, fiscal sponsorship providing infrastructure support to emerging initiatives, and donor advised funds. Proteus Fund focuses on the interconnected goals of racial, gender, queer, and disability justice alongside an inclusive, fully representative democracy. Since Paul Di Donato became President & CEO in 2016 (after previously directing the successful Civil Marriage Collaborative), Proteus has expanded to support 25 funds and initiatives. The organization has earned a 4-star rating from Charity Navigator and is recognized as a leader in collaborative philanthropy.

Decision Timeline

Specific decision timelines vary by program and are not publicly disclosed. The RISE Together Fund reviews applications on a rolling basis, suggesting relatively rapid turnaround. Given the emphasis on "moving quickly to respond to urgent movement needs," Proteus appears to prioritize responsive grantmaking over rigid annual cycles.

Success Rates

Not publicly disclosed. With 291 grants awarded in 2023 from a $21.8 million budget, average grant size across all programs was approximately $75,000, though this varies significantly by program (RTF averages $15,000 while some grants reach $1.5 million).

Reapplication Policy

Not explicitly stated in public materials. For the RTF Small Grants program with rolling deadlines, applicants can likely reapply in subsequent funding rounds. For relationship-based collaborative funds, ongoing communication with program directors would inform reapplication timing.

Application Success Factors

Mission Alignment is Critical: Proteus Fund emphasizes the interconnected nature of their work: "We cannot realize one without the other – making progress on all fronts is essential to realizing their vision of a more equitable, just, and democratic future." Applications should demonstrate understanding of intersectional justice, not siloed issue work.

Grassroots Movement Connection: Recent grantmaking prioritizes grassroots organizations in the U.S. working in social justice and democracy. Strong priority goes to "collaborative and collective movements toward social change." Demonstrate your organization's role within broader movement ecosystems.

Strategic Positioning: Proteus values organizations that work at the intersection of multiple strategies: community organizing, policy advocacy, litigation, narrative development, and communications. Show how your work creates "lasting change" through multi-pronged approaches.

Flexibility and Innovation: The organization seeks partners who can "balance long-term strategies while remaining flexible enough to shift tactics and priorities in response to evolving circumstances." Demonstrate adaptive capacity alongside strategic vision.

Read Guidelines Carefully: For RTF Small Grants, "applicants are advised to read the priorities, criteria, and process carefully before applying." This suggests applications that don't align with stated priorities are declined.

For Relationship-Based Funds: Since most collaborative funds don't accept unsolicited proposals, building relationships with program staff is essential. Attend sector convenings, engage with current grantees, and demonstrate you're part of the networks Proteus already supports.

Recent Funding Examples:

Voter Participation Center: $1.5 million (2023)
Grassroots International: $750,000 (2023)
Movement Strategy Center: $750,000 (2023)
Funders United for Democracy and Trans Justice: Proteus Fund's "single largest grant to date supporting transgender justice"
Disability Culture Lab: Flexible support grant enabling staff hiring and program launch including in-house communications firm

Key Takeaways for Grant Writers

Know your collaborative fund: Each of Proteus's donor collaboratives has distinct priorities. Research which fund aligns with your work before reaching out (Piper for democracy/protest rights, RTF for BAMEMSA communities, RFDC for reproductive/LGBTQ rights, Solidarity for cross-movement work).
Demonstrate intersectional analysis: Proteus explicitly rejects single-issue work. Show how your efforts connect racial, gender, queer, and/or disability justice with democracy-building.
Build relationships proactively: With most funds operating on invitation-only or relationship-based models, attend sector events where Proteus staff participate, connect with current grantees, and use the contact forms on specific program pages to introduce your work before formal opportunities arise.
Emphasize collaborative approach: Proteus values "collective movements" and operates through "collaboratives." Highlight partnerships, coalition work, and how your organization amplifies broader movement strategies rather than working in isolation.
Focus on narrative change: Proteus explicitly prioritizes "promoting narrative change" as a critical strategy. If your work includes communications, media, or cultural strategy components, emphasize these.
For RTF Small Grants applicants: This is your best entry point with an open application process. Even if you need more than $25,000, consider applying here to get on Proteus's radar and demonstrate impact for future larger opportunities.
Show long-term vision with adaptive tactics: Proteus seeks partners who balance strategic planning with responsiveness to "evolving circumstances on the ground." Demonstrate both your theory of change and your capacity to pivot when needed.
