Quixey is a company located in Mountain View, California that calls itself "The Search Engine For Apps." Users can search for an app on Quixey by describing in natural language what they want to do. The company invented a new type of search, "Functional Search," that gathers app information from review sites, blogs, social media sites, and additional sources. The technology allows users to search across multiple platforms, eliminating the need for multiple searches using different mobile devices. In 2015, Quixey raised a $60 million investment round at a valuation of approximately $600 million. Quixey’s Functional Search technology uses data from across the web (blogs, review sites, social media outlets, and more) to learn exactly what each app can do. With this data, the search engine enables users to find apps without knowing the name or description. Quixey was co-founded in 2009 by Chief Strategy Officer Tomer Kagan and Chief Science Officer Liron Shapira. The company spent a year and a half building Functional Search before it launched in private beta on April 7, 2011.
