Ecosia is a Berlin-based search engine company founded in 2009 that operates on a unique business model where it uses profits from search advertising to fund tree-planting projects worldwide. The company generates revenue through search ads powered by Microsoft Bing's advertising network, dedicating at least 80% of its surplus income to environmental initiatives. Ecosia has planted over 180 million trees across more than 35 countries as of recent reports. In the AdTech ecosystem, Ecosia operates as a search advertising platform that partners with Microsoft Advertising (formerly Bing Ads) to display sponsored search results. While it competes in the search engine market dominated by Google, Ecosia differentiates itself through its environmental mission and transparency, publishing monthly financial reports showing how ad revenue is allocated. The company is certified as a B Corporation and has positioned itself as a privacy-focused alternative that doesn't create permanent user profiles or sell data to third parties. Ecosia's user base has grown to over 20 million active users globally, appealing primarily to environmentally-conscious consumers and organizations seeking sustainable alternatives to mainstream search engines. The platform's AdTech relevance lies in its demonstration of purpose-driven advertising models and its role as an alternative inventory source for search advertisers through the Microsoft Advertising ecosystem.
