Wikimedia Foundation

The Wikimedia Foundation is a nonprofit organization founded in 2003, headquartered in San Francisco, California. It operates Wikipedia and other Wikimedia free knowledge projects, which are among the world's most visited websites. The Foundation's mission is to empower and engage people globally to collect and develop educational content under a free license, accessible to everyone.

Wikimedia projects are maintained by a global community of volunteers who contribute to creating and curating content. The Foundation supports these projects by keeping the sites fast, secure, and accessible, as well as by defending them legally and building new features and tools. With approximately 450 employees, the Wikimedia Foundation relies on donations from millions of users and institutions to fund its operations and initiatives.
