Who Are We?

Menomadin Foundation is an Israeli-based international impact fund, which aims to meet the world’s most pressing environmental and social challenges, as outlined by the UN’s Sustainable Development Goals (SDGs).

Through our unique Impact Management Platform, we integrate 3 channels of operation: Strategic Philanthropy endeavors in Israel and Africa, Impact Investments in impact start-ups and innovative impactful financial POCs, and Cross-Sector Partnerships, aiming to achieve globally scalable, holistic, value-chain solutions.

Menomadin Foundation was established in 2019 by businessman and philanthropist Haim Taib, the Founder and President of our sister company the Mitrelli Group, out of the experience and knowledge he gained throughout decades of business and philanthropic activity in Africa, developing countries and empowering communities.

Taking under our wings our Angolan subsidiary Fundação Arte e Cultura, Menomadin Foundation nurtures bold dreams in Africa, in Israel and around the world, leading humanity toward sustainable development for people, planet and prosperity.
