The Helidoni Foundation concentrates its funding on a small set of mission-driven organizations that pilot and scale practical solutions in education, ecological restoration, and civic technology. They favor organizations building programs and platforms — school training initiatives, ecosystem pilot projects, and open governance tools — and provide sizable, unrestricted or program-focused grants to help launch or expand flagship efforts.
The Helidoni Foundation Inc. has made one of its largest recent commitments to Ten Million Hands, including a $285,000 grant in 2025 for a school training program after earlier support of $150,000 in 2023 as a founding donor and $100,000 in 2024 for the same program. That pattern shows how the foundation backs organizations over time when a project is still being built and expanded. Across its recent grants, the foundation favors practical work that can be piloted, launched, or extended: school-based training, ecological restoration, civic technology, and stewardship. It has also supported open governance infrastructure through Schema Labs’ OpenCouncil, along with multiple grants to Ecogenia for Dorida and Chania pilots. The portfolio includes general support for mission-driven groups as well as project-specific funding, suggesting a mix of operating backing and targeted program grants. The grant list also shows attention to education-linked efforts beyond a single institution. Awards to Social Hacker Academy supported scholarships for Greek residents outside major cities in a seven-month blockchain career track, while Scico received funding for STEM in Tanzania. These grants point to a funder interested in skills development, local capacity, and new models that can serve students and young professionals.
In education and skills training, The Helidoni Foundation Inc. funded Ten Million Hands for a school training program and supported Social Hacker Academy with 10 scholarships for Greek people who reside outside major big cities in Greece to join a seven-month blockchain career track. It also gave Scico $10,000 for STEM in Tanzania. Its ecological and community-focused grants include $100,000 and $75,000 to Ecogenia for Dorida & Chania pilots, plus support for Incommon’s “Close the Food Circle” work in the Municipality of Papagos-Holargos. Those grants show interest in pilot projects that connect local systems, restoration, and community practice. The foundation also backed cultural and civic projects. Schema Labs received funding to develop and launch OpenCouncil, while World Human Forum was supported for the Eleusis Symposium 2023. Fashion Revolution and Impact Hub Labs also appear in the recent grant list, tied to a summer school on fashion and a conscious consumption project.

Concentrated portfolio with relatively few, large grants; multiple repeat awards to priority grantees (several organizations received three grants each). Funding is a mix of program-specific and unrestricted support aimed at launching pilots or scaling flagship projects rather than many small, one-off gifts.
Notable grantees: Ten Million Hands, Ecogenia, Schema Labs, Stewards, THI VIA
Typical grants cluster around the middle of five figures: the 25th percentile is $9,750, the median is $17,500, and the 75th percentile is $56,250. The recent list includes both smaller project grants and larger multi-year commitments, with repeated awards to the same organizations across 2023, 2024, and 2025. The pattern suggests relationship-based funding rather than one-time awards. Grants appear to be made by a private foundation structure, and the funder does not make program-related investments or grants to individuals.
The Helidoni Foundation Inc. gives regionally, with most grants going to recipients in Greece. In the recent grant list, Athens appears repeatedly, alongside Marousi, Neo Psychiko, Chalandri, Thessaloniki, Ioannina, Lavrio, and Athenes. Massachusetts is the top U.S. state by grant count, but the available recipient locations show only one U.S.-based grantee, Thi Via in Brooklyn, NY. No grants in the recent list go to recipients in New Hampshire.
The recent grant list shows support for school training programs, ecological restoration pilots, civic technology, stewardship, fashion education, food-system projects, public health, cultural events, and scholarships.
