While Ecosia is not technically a non-profit, no one can sell Ecosia shares at a profit.

> Ecosia says that it was built on the premise that profits wouldn’t be taken out of the company. In 2018 this commitment was made legally binding when the company sold a 1% share to The Purpose Foundation, entering into a ‘steward-ownership’ relationship.

> The Purpose Foundation's steward-ownership of Ecosia legally binds Ecosia in the following ways: - Shares can't be sold at a profit or owned by people outside of the company and - No profits can be taken out of the company.
