The Wikimedia Foundation is the non-profit organization that supports and hosts Wikipedia and several other Wikimedia free knowledge sites. Every month, the Wikimedia sites are accessed by more than a billion unique devices. Wikipedia consists of more than 40 million articles across hundreds of languages. Every month, more than 250,000 volunteer editors contribute to Wikipedia. Based in San Francisco, California, the Wikimedia Foundation is an audited, 501(c)(3) non-profit that is funded primarily through donations and grants. It currently employs over 300 staff members.
At the Foundation, we build technology to help people everywhere access Wikipedia, across devices and in nearly 300 languages. We engineer privacy for our readers and editors so they can safely and securely explore Wikipedia. We create programs and initiatives to make Wikipedia freely available to more people in more parts of the world. We build new tools for the community of editors so they can continue to improve and grow Wikipedia. Roughly a quarter of our budget goes to supporting the community that make the site possible, including through grantmaking programs that enable volunteers and enrich the information on the sites.
