Vimeo /ˈvɪmiːoʊ/ is a U.S.-based video-sharing website on which users can upload, share and view videos. It was founded by Jake Lodwick and Zach Klein in November 2004. They left the company in 2007 and 2008 respectively. The name Vimeo was created by co-founder Jake Lodwick and is a play on the word video, inserting the word "me" as a reference to the site's dedication to user-made video and is also an anagram of the word "movie".

IAC/InterActiveCorp purchased Vimeo in August 2006, as part of its acquisition of Connected Ventures. Dae Mellencamp is the Chief Executive Officer of Vimeo. In January 2009, Mellencamp joined IAC as General Manager of Vimeo.
