What Helidoni Foundation does

Helidoni Foundation is a privately held non-profit foundation established in 2019 and operating from Athens, Greece, that makes grants to mission-first organizations working on social and environmental challenges in Greece. The Foundation's stated theory of change centers on Steward-Ownership (S.O.), a legal-ownership model that protects organizational mission against extractive capital, and the Foundation explicitly funds organizations at various stages of adopting or operating under this structure.

The Foundation's "products" are its grant programs and co-funded initiatives rather than software or services. Documented programs include Ten Million Hands (sustainable consumption), Open Council by Schema Labs (civic-tech for transparency and governance), Althyna (elder fall prevention), The Kali Polis Project (urban resilience at the American College of Greece), and the Astylab Founders program co-run with Stewards. The Foundation also co-launched the Venture Impact Awards (VIA) with The Hellenic Initiative in 2020 and acts as a founding donor of Stewards, the Greek promoter of the S.O. model. Since 2020, the Foundation has supported over 50 organizations across at least 12 UN Sustainable Development Goal categories.

The Foundation's go-to-market is direct, relationship-driven grantmaking; it does not sell products or services and discloses no pricing model. Distribution is single-country (Greece), with outreach conducted through the Foundation's website, news articles, and high-visibility convenings such as the Panathēnea Festival 2026, where it hosted a panel on steward-owned business models alongside Purpose Foundation and grantees. The team is small (1-10 employees), led by Managing Director Alexis Zitrides, who also runs the related Helidoni Group, with Dimitris Georgakopoulos serving as President. No revenue, assets under management, or grant pool size is publicly disclosed.
