About Siegel Family Endowment C/O Lyudmila Koyenova
The Siegel Family Endowment gives like a mission-driven technology philanthropy, concentrating on organizations that shape how technology is taught, designed, and governed. A large share of its support goes to elite universities and research centers working on public interest technology, AI, future-of-work questions, and technology’s social impacts, alongside major investments in K-12 computer science and STEM access. It also backs scalable education platforms and field-building organizations, especially in New York and through national networks.

Giving Approach
Highly concentrated, high-dollar grantmaking with many repeat grantees and multi-purpose support to build institutional capacity, scale programs, and sustain field infrastructure. The foundation favors a mix of anchor funding for core partners and strategic investments in networks, fellowships, and research hubs rather than widely distributed small grants.
About Siegel Family Endowment C/O Lyudmila Koyenova
Siegel Family Endowment C/O LYUDMILA KOYENOVA makes very large, highly concentrated grants, with three recent awards all in New York and each above $24 million. That pattern points to major institutional support rather than a broad spread of small grants. The foundation’s active programs center on Learning, Work, and Infrastructure, and its grantmaking is described as invitation-based and collaborative, with some funding routed through pooled or collaborative initiatives. In the grant record provided, the largest recent award was $27,792,259 in 2025 to SEE Attachment 22 in SEE Attachment, NY, followed by $26,907,603 in 2024 to SEE Attachment 21 in SEE Attachment, NY. A third recent grant of $24,771,536 went in 2023 to SEE Attachment 15, also in SEE Attachment, NY. The structure of those awards suggests support for long-term institutional or affiliated philanthropic vehicles, alongside the foundation’s stated focus areas in learning systems, workforce questions, and infrastructure.
What Siegel Family Endowment C/O Lyudmila Koyenova Funds
In learning, Siegel Family Endowment C/O LYUDMILA KOYENOVA funds adaptive and equitable learning systems, including learner-centered ecosystems, computing education, responsible education technology, and research-policy-practice connections. The foundation also supports workforce work tied to AI and emerging workplace technologies, with emphasis on worker-informed research, pilot programs, and field-building around job quality and equitable opportunity. Infrastructure is a third portfolio, aimed at the connective tissue that supports learning and work, including shared evidence, scalable models, and cross-sector collaboration. One open-call initiative appears in the learning area: the Learning Landscapes Challenge, described as a signature call for proposals related to learning and educational ecosystems.
How Siegel Family Endowment C/O Lyudmila Koyenova Gives
The recent grant record is extremely concentrated: the p25, median, and p75 grant sizes are $25,305,553, $25,839,570, and $26,373,586, respectively. That narrow range shows a consistent pattern of very large awards rather than a mixed portfolio of small and medium grants. The foundation is a regular funder, not a DAF and not a funder of individuals. Its core grantmaking is invitation-based, with some grantmaking also routed through pooled and collaborative funds. The presence of a signature open call in learning adds one clearer application route, but the main pattern is relationship-led rather than open solicitation.
