Ecosia

Ecosia GmbH is a German search-engine company headquartered in Berlin, founded in 2009 by Christian Kroll. Since 2018 the company has operated under a steward-ownership model via the Purpose Foundation: shares cannot be sold and dividends cannot be paid externally, making Ecosia structurally impossible to acquire.

Roughly 80% of ad-revenue surplus is reinvested into reforestation projects (200M+ trees planted as of 2026). In May 2026, alongside Qwant, Ecosia began serving results from EUSP (European Search Perspective), the independent EU search index the two companies have co-built since 2024 — the first time in 16 years Ecosia has delivered its own results rather than relying purely on Bing.
