Overview
The Jaket Foundation (formerly known as the Gross Family Foundation) was established in 1998 by Phillip Gross, co-founder of Adage Capital Management, LP, and his wife Elizabeth. The foundation is a private independent foundation with over $100 million in assets. In recent years, the foundation's grantmaking has grown substantially, from approximately $3 million earlier in the decade to $12.4 million in 2023 (29 awards) and $2.6 million in 2022 (17 awards). The foundation funds grants almost entirely in the Boston area for youth services, education, and athletics. Phillip Gross is also a founder and treasurer of Strategic Grant Partners, a Boston-based collaborative philanthropy organization supporting projects that improve the lives of struggling individuals and families in Massachusetts.

Application Success Factors
Since this foundation does not accept unsolicited applications, organizations cannot apply directly. However, understanding their funding patterns can help organizations position themselves strategically:
Demonstrated Track Record: The foundation supports established organizations with proven impact in their focus areas. Recent grantees include well-known Boston institutions like SquashBusters and the Boys and Girls Clubs of Boston.
Geographic Alignment: Nearly all grants are made to organizations serving the Boston and Concord, MA area. Organizations outside this geography are rarely funded.
Youth Focus: The strongest funding pattern is support for youth-serving organizations, particularly those involving athletics or educational enrichment. As noted in research, "the family usually awards several grants each year in amounts ranging from $5,000 to $250,000 to Boston-based Youth Enrichment Services."
Educational Institutions: The foundation has made significant grants to educational institutions, particularly those with connections to the founders. Major education grants include $10 million to Mount Holyoke College (2021), $6.8 million to University of Maryland at College Park (2020), $2 million to Harvard University, $1 million to Fenn Schools, and $400,000 to Tufts University.
Scale Flexibility: The foundation funds both small grassroots initiatives ($2,500-$10,000) and major institutional projects ($1 million+), suggesting they evaluate projects on merit and impact rather than organizational size.
Key Takeaways for Grant Writers

- Relationship-Driven: Grants flow from personal relationships, board connections, and the Strategic Grant Partners network. Focus on building visibility in Boston's philanthropic community rather than direct outreach.
- Boston-Centric: Geographic focus is almost exclusively the Boston and Concord area with emphasis on inner-city youth programs.
- Youth Athletics Priority: Organizations combining youth development with athletic programming (especially water/snow sports) align strongly with funding patterns.
- Education and Institutional Giving: Major grants to educational institutions, particularly for financial aid and scholarships, represent a significant portion of giving.
- Strategic Grant Partners Connection: Phillip Gross's role as founder and treasurer of Strategic Grant Partners suggests this collaborative may be a pathway for organizations to gain visibility with the foundation.
- Growing Grantmaking: Annual giving has grown from ~$3 million to over $12 million in recent years, indicating expanded capacity and interest in philanthropy.
