Bridging philanthropy and purpose-driven entrepreneurship for a sustainable future.
We support mission-first organizations that deliver tangible social benefits and create meaningful change to people and the planet
Our theory of change revolves around the concept of Steward-Ownership (S.O.), with an emphasis on connecting philanthropy and social entrepreneurship.
We support the adoption of the S.O. model, from early-stage or developed concepts, addressing social or environmental challenges.
We empower organizations to achieve financial independence and amplify the purpose they were created for.

We're proud to announce a Grant to Althyna, a new venture working to prevent falls among older adults in Greece.
We're proud to announce a Grant to Althyna, a new venture working to prevent falls among older adults in Greece.
In Greece, 1 in 3 people over 60 fall every year, with more than half of these incidents happening at home. The human and financial cost is significant, with over €1 billion spent annually on fractures alone.
Althyna's founder, Giannis Iakovakis, is tackling this with a simple starting point: make homes safer. Assessments, practical modifications, and a clear plan to prove the model across 100 households.
Althyna is also one of the first ventures in Greece to adopt a steward-ownership structure, meaning the mission is protected by design, not just by intention.
The venture came out of Astylab Founders, a programme we co-funded with Stewards and run by Astylab and Idea Machines. Eight founders, eight weeks, four ventures ready to launch. The programme returns in 2026.
“Prevention starts at home. With Althyna, we support practical solutions that make living environments safer for those most at risk.” – Alexis Zitrides, Managing Director, Helidoni Foundation

Helidoni Foundation * Storymentor
We’re proud to support Storymentor, a storytelling organization that strengthens communication capacity and amplifies voices for social good. Since 2019, Storymentor has worked with more than 120 organizations, helping changemakers articulate their mission and impact with clarity and authenticity.
Through our support, Storymentor is launching Good Stories Labs, a capacity-building program bringing storytelling and presentation skills to regional Greece. The program will deliver five full-day workshops across cities including Herakleion, Ioannina, Larissa, Kalamata and Alexandroupoli, reaching 75 - 100 participants from civil society, education and the creative sector.
By equipping changemakers with the tools to communicate their work effectively, the initiative addresses a critical visibility gap - enabling organizations to build partnerships, attract support and expand their impact.
“Through this support, we aim to empower changemakers across Greece to share their stories with clarity and confidence, strengthening their ability to create lasting impact.” - Alexis Zitrides, Managing Director, Helidoni Foundation

Helidoni Foundation * Archipelagos Institute of Marine Conservation
We’re thrilled to support Archipelagos Institute of Marine Conservation, an organization that has dedicated nearly 30 years to protecting the biodiversity of the Northeastern Mediterranean. Through research, conservation, and education, they safeguard fragile marine ecosystems and inspire the next generation of marine scientists.
Archipelagos is upgrading its research vessel Triton, adding essential sails, reefing systems, and a low-energy desalination unit. These upgrades will allow longer, safer, and more effective expeditions, supporting biodiversity monitoring, pollution assessments, and community-based conservation projects.
“Through this support, we’re helping Archipelagos expand its research and continue inspiring young people and local communities to actively protect marine life in the Mediterranean.” - Alexis Zitrides - Managing Director, Helidoni Foundation
