Greaterthan trains, supports and advises teams and organizations at the forefront of decentralized, self-managed and participatory work. We work with leaders, companies, startups, cooperatives, networks and communities who want to change how they organise. As a collective of experienced practitioners, we not only support others on their journey, but develop open source tools & products, conduct research and run experiments. Our mission is to grow new organising structures & cultures that contribute to a more healthy system for all.

Bring people, ideas and money together, encouraging participation at every stage.

Founded in January 2012 in Paris, OuiShare rapidly evolved from a dozen enthusiasts to a global community spread across Europe, Latin America and the Middle East, and is an international leader in the field of collaborative economy, future of cities and the future of work.Today, the members of Ouishare spend a lot of time questioning, experimenting, and deconstructing the myths of our time as well as our own idealistic visions: collaborative practices, shared governance, decentralization, smart cities. We like to move into areas where we are not expected and are always exploring the edges to find new ways to address the many challenges of our time.OuiShare activities consist in building community, producing knowledge and incubating projects as well as offering support to individuals and organizations through professional services and education. I support organisations in implementing collaborative principles, teach those at universities and give public talks.
