Overview
The Onion Foundation is a private philanthropic foundation established in 2014 by Maine technology entrepreneur Frederick "Fritz" Onion (co-founder of Pluralsight Inc.) and his wife Susan Onion. With assets of $63.6 million, the foundation has made over 1,500 grants totaling more than $27 million to over 600 unique nonprofit organizations since its inception. The foundation's mission is to build a more equitable and healthy Maine by deepening the connection of all people to the arts and nature. In 2022, the foundation reached a significant milestone by appointing Diana Morris as its first executive director, signaling a shift toward more professional grantmaking operations. The foundation is recognized as one of Maine's top 25 funders and maintains an active presence in the state's philanthropic community through the Maine Philanthropy Center.

Founders' Philosophy: Fritz Onion has stated: "We feel that philanthropy has an important role in helping address the systemic inequities in our society today. It is an odd feeling to understand that you have the ability to make change, to help others and to enable nonprofits to do the work they do." Susan Onion emphasized collaboration: "The philanthropic community in Maine is small and there's a lot of sharing of practice… a lot of collaborative work."

Application Success Factors
Alignment with Strategic Priorities: The foundation has clearly articulated strategies for both arts and environment programs. Successful applications should explicitly demonstrate how they advance one or more of these strategies, particularly around equity, access, and capacity building.
Pre-Application Engagement: The foundation's strong encouragement to discuss proposals with program officers before applying suggests that relationship-building and alignment-checking are valued. Organizations that take advantage of this opportunity likely have better success rates.
Equity and Inclusion Focus: The foundation explicitly states it "values efforts to reach rural and underserved populations, foster collaborations, include diverse perspectives, learn from field experts, increase access to opportunities, and apply practices to further social and racial equity." Applications should clearly demonstrate these commitments.
Maine Focus: All funded work must be based in Maine and benefit Maine's people. The foundation emphasizes reaching rural and underserved populations within the state, not just urban centers.
People-Centered Approach: Particularly for environment grants, the foundation explicitly focuses on "people of Maine, whose lives and behaviors will continue to shape environment and climate change outcomes" rather than land acquisition or capital projects. Applications should emphasize human impact and behavior change.
Innovation and Learning: Discovery Grants specifically support "a new learning or innovative approach" and encourage trying something new. The foundation appears to value organizational development and willingness to experiment.
Multiyear Relationships: The foundation offers multiyear grants (up to three years) for both general operating and project support, indicating they value sustained partnerships rather than one-time funding relationships.

Maine focus is non-negotiable: Projects must be based in Maine and benefit Maine's people. Demonstrate deep understanding of Maine communities, particularly rural and underserved populations.
-
Innovation is welcome in Discovery Grants: If you're testing something new, use the Discovery Grant program rather than applying for larger amounts. The foundation explicitly wants to support new learnings and innovative approaches.
-
Engage with the philanthropic community: Fritz and Susan Onion emphasize that "the philanthropic community in Maine is small" with "a lot of collaborative work." Building relationships through events like Maine Philanthropy Center gatherings may be valuable.
