Trust score

Wikipedia.org is operated by the Wikimedia Foundation, Inc., a San Francisco-based 501(c)(3) nonprofit founded in 2003 by Jimmy Wales. The Foundation funds and supports Wikipedia and related Wikimedia projects through donations, grants, and Wikimedia Enterprise services rather than conventional commercial investment. It has nearly 700 staff, publishes audited financial reports, and reports substantial global reach. Public Trustpilot ratings are poor, but those ratings reflect user reviews and should be weighed against the organization’s transparency, nonprofit status, and broad use.
