Einhorn Collaborative

Einhorn Collaborative is not a traditional grantmaker — it is a relationship-first funder collaborative that primarily functions as a convener, thought leader, and infrastructure builder for the field of social cohesion. Founded in 2002 by David Einhorn, the founder of Greenlight Capital, and led by Executive Director Jennifer Hoos Rothberg (compensated at $689,557 annually as of 2022), the foundation operates as a private trust funded exclusively through Einhorn family giving vehicles including the Einhorn Family Fund at J.P. Morgan Charitable Giving Fund and National Philanthropic Trust.

All grantmaking is by invitation only. The foundation's website states unambiguously: "We do not accept unsolicited funding proposals." This is not a soft deterrent — it is the operating model. Einhorn proactively identifies partners whose work aligns with its four pillars (Bonding, Bridging, Building, and Belonging) and initiates relationships on its own terms. This saves time for grant seekers who would otherwise invest months in a fruitless application process.

The relationship pathway is non-linear and almost always begins in collaborative settings. Einhorn co-founded and funds the New Pluralists funder collaborative, convenes the Early Childhood Funders Collaborative through Third Sector New England (its largest recorded external grantee at $52,500 across three grants), and organizes peer convenings for funders, researchers, and practitioners across ideological lines. Organizations that become known within these funder networks — especially New Pluralists — are best positioned for eventual partnership.

For first-time prospective partners, the essential reality is that there is no application path. The foundation funds 501(c)(3) organizations working at national scale across sectors including higher education, healthcare (particularly pediatric early relational health), civic institutions, K-12 education, national service, public media, and academic research. It explicitly does not fund startups, primarily local organizations, capital projects, humanitarian relief, or organizations engaged in political advocacy of any kind.

Six guiding principles shape every relationship: Relationship First, Better Together, Sharing the Journey, Focusing on Key Levers, Seeking Transformational Impact, and Always Learning and Improving. Organizations that can demonstrate sustained cross-partisan work, a track record of bridging ideological divides, and genuine willingness to co-learn with funders fit the profile. The foundation explicitly prizes work that can "withstand the test of time because it is built on broader consensus rather than narrow agreement."

Einhorn Collaborative's financial profile reflects a foundation in visible transition. Total assets have declined from a peak of $34.8 million in 2019 to approximately $17.0 million in fiscal year 2024 — a 51% contraction over five years driven by ongoing grantmaking and operating expenses with minimal new contributions ($0 in contributions received in both 2021 and 2022, $122,551 in 2019). David Einhorn has shifted his philanthropic vehicle structure, with most new giving now flowing through donor-advised funds at J.P. Morgan and National Philanthropic Trust rather than directly into the trust.

Total giving has been remarkably stable at approximately $3.8 million per year across 2021-2023 ($4.4 million in 2020, $3.8 million in 2021, $3.8 million in 2022, $3.8 million in 2023). However, these figures are misleading for grant seekers: the vast majority of "total giving" represents the foundation's own operating expenses, staff, and program costs — not external grants to other organizations. Grants actually paid to external organizations were dramatically smaller: $593,305 (2020), $57,539 (2021), $76,790 (2022), $96,330 (2023). External grantmaking represents roughly 1.5-2.5% of total giving in recent years.

Among recorded external grants, amounts are modest by any measure. The median grant is approximately $10,000, with a range from $180 (small charitable donations to organizations such as Temple Shaaray Tefila and Cleveland Clinic Foundation's VeloSANO initiative) to $52,500 (Third Sector New England for Early Childhood Funders Collaborative support). The 15 largest recorded grantees received a combined $173,120 across 21 grants, averaging $8,244 per grant. Geographic concentration clusters in DC (7 grants), Massachusetts (5), California (3), and New York (2).

Program expenditures reveal the real funding story: New Pluralists Funder Collaborative Design consumed $499,713 and the Builders Partner Collaborative Support consumed $327,748 in a single program year — dwarfing all direct external grants combined. The foundation's primary funding vehicle is hosting and operating collaboratives, not writing checks to individual nonprofits. Organizations seeking meaningful financial support (above $50,000) should understand that the real value of an Einhorn relationship is convening support, field amplification, and co-funding strategy access — not a direct grant.

The table below compares Einhorn Collaborative to its closest asset-equivalent peer foundations identified through IRS data. These peers share a similar balance sheet (~$17M) but differ in focus and strategic model, illustrating Einhorn's distinct position within the Philanthropy & Grantmaking category.

What sets Einhorn Collaborative apart from these asset-equivalent peers is its operating model and national field-building scope. While most foundations in the $15-20M asset range function as traditional check-writers, Einhorn primarily functions as a field-builder — convening peer funders, co-creating collaboratives such as New Pluralists, and operating thought leadership programs. This means its philanthropic leverage exceeds what its $17M balance sheet suggests: the New Pluralists Collaborative, which Einhorn helped design and launch, aggregates dozens of funders whose combined giving in pluralism vastly outpaces Einhorn's own. For grant seekers, the strategic positioning question is not "How do I get a grant from Einhorn?" but rather "How do I become a partner Einhorn convenes around?"

In 2025, Einhorn Collaborative accelerated its campus pluralism strategy with two significant announcements. The foundation partnered with the Institute for Citizens & Scholars to launch the College Presidents for Civic Preparedness initiative, targeting university leadership to institutionalize cross-partisan dialogue and civic culture at campuses nationwide. Separately, the Pluralism Accelerator Fund was launched to extend Einhorn's decade-long Cornell University model to the broader higher education system. The class of 2029 at Cornell is now on track to achieve the foundation's 10-year goal of ensuring 100% of undergraduates complete a high-quality community-engaged learning experience — a milestone celebrated in late 2025.

In March 2025, Einhorn co-sponsored a national summit on Early Relational Health alongside Nurture Connection and Reach Out and Read in partnership with the American Academy of Pediatrics, convening participants from 23 communities across 18 states. The National Academies of Sciences, Engineering, and Medicine also published findings in 2025 emphasizing the importance of strong positive relationships for young children, which Einhorn cited as shaping its Bonding strategy.

The foundation released its Social Connection in America 2025 Survey, a 25-year longitudinal study tracking connection trends nationally. Executive Director Jenn Hoos Rothberg was featured in McKinsey's "Conviction and Connection" philanthropy leadership report. As of mid-2026, the foundation is actively recruiting a Bridging Strategy Lead, signaling ongoing programmatic investment. Total assets stood at $17.0 million in fiscal year 2024, with total revenue of $1.4 million — down from $20.2 million in assets at the end of fiscal year 2023, reflecting the foundation's ongoing spend-down trajectory.

Because Einhorn Collaborative accepts no unsolicited proposals, the realistic pathway for organizations seeking to enter Einhorn's orbit requires relationship cultivation, not proposal writing. Here is what actually works.

Build visibility in Einhorn's collaborative networks first. The New Pluralists collaborative, managed through Third Sector New England (Einhorn's largest external grantee at $52,500 across three grants), is the primary funder community where Einhorn staff identify potential partners. Organizations working in pluralism and bridging divides should pursue active engagement with New Pluralists — attending convenings, contributing to shared learning, and demonstrating cross-partisan partnerships. For organizations focused on early childhood and pediatric relational health, the Early Childhood Funders Collaborative and its annual summit (co-sponsored by the American Academy of Pediatrics) serve the same function.

Engage with Einhorn's thought leadership publicly. The foundation releases major research — including the Social Connection in America 2025 Survey — and its staff notice when organizations build on their work. Cite their publications in grant reports to other funders, invite Einhorn-affiliated researchers to panels, and contribute your own research to debates the foundation is actively tracking (currently: affective polarization in youth, campus civic culture, early relational health systems).

Demonstrate cross-partisan credibility explicitly. The FAQ makes clear Einhorn funds no political advocacy. More importantly, its six guiding principles require partners to work across ideological lines. Organizations with documented conservative-liberal coalition partnerships, or outcomes data across politically diverse communities, are dramatically more compelling than those serving a single ideological constituency.

Work at national scale. The FAQ explicitly excludes primarily local organizations. Multi-state reach, national policy engagement, or practice standards that apply broadly are the markers Einhorn looks for.

Make contact thoughtfully. The foundation's contact email is hello@einhorncollaborative.org. Any outreach should be framed around a shared field-level question or learning opportunity — not a funding request. Reference specific Einhorn publications or initiatives to signal genuine familiarity. Timing contact around new initiatives (the Pluralism Accelerator Fund, the Bridging Strategy Lead hire) creates natural entry points for a conversation.
