WikiMedia Foundation

About: 

The Wikimedia Foundation is the non-profit organization that supports and operates Wikipedia and the other free knowledge projects. All of our work is guided by our mission to share the sum of all knowledge with every person in the world. We keep the websites fast, secure, and available. We support the community of volunteers who contribute to the Wikimedia projects. We make free knowledge accessible wherever you are — on your phone or laptop, on a boat in the South Pacific, or in the hills of Nepal. We help bring new knowledge online, lower barriers to access, and make it easier for everyone to share what they know.
