Yippy was a metasearch engine that grouped searched results into clusters. It was originally developed and released by Vivísimo in 2004 under the name Clusty, before Vivisimo was later acquired by IBM and Yippy was sold in 2010 to a company now called Yippy, Inc. At the time, the website received 100,000 unique visitors a month.

As of August 2019, Yippy's main page states their searches are powered by IBM Watson, asserting it is "the right search" (italics theirs) that "delivers fair search results based on balanced algorithms."

In 2019, Yippy, Inc. CEO Rich Granville presented the search engine as free of censorship of conservative views and called the company an "intelligence enterprise" with high-level White House connections.

As of 2021, the website redirects to DuckDuckGo.
