Cuil was a stealth search engine startup nearby the year 2005, which claimed that it can index web pages significantly faster and cheaper than Google. Cuill has told potential investors that their indexing costs will be 1/10th of Google’s, based on new search architectures and relevance methods. In some ways Cuil is the polar opposite of Powerset, which has huge indexing costs because it does a deep contextual analysis on every sentence on every web page. Powerset’s indexing costs, therefore, should be much higher per web page than Google’s.
Cuil was also founded by highly respected search experts. Husband and wife team Tom Costello and Anna Patterson were joined by Russell Power. Patterson and Power are ex-Google search experts. Costello was the founder of Xift.
Cuil met with venture capitalists. They now have 10-15 employees and an office in Menlo Park.
Today is hard to find it in search engines.
