Description
Freetree was Ecosia's browser extension that monetised online shopping via affiliate commissions (revenue paid by merchants for referred sales) and channelled proceeds into Ecosia's tree-planting programme. Launched in 2022 under the same steward-owned, mission-locked parent as Ecosia search, it applied an identical funding mechanism to a different host behaviour. Ecosia shut it down in June 2025, citing failure to reach sufficient users for sustainable scale.
Funding
Lessons learned
- The affiliate-commission-funds-mission mechanism requires the host behaviour to be frequent and frictionless; installing and actively using a shopping extension is far less habitual than searching, and adoption never reached self-sustaining scale.
- Ecosia closed Freetree in June 2025 because it 'never reached enough users to scale sustainably' — confirming that the funding model only works if the underlying product achieves mass adoption, regardless of how sound the mechanism is.
- A mission-locked ownership structure protects the parent mission but does not protect individual sub-products from being retired if they cannot cover their own costs.
