Cuil is a search engine that went live on July 28, 2008. Cuil's developers aimed to surpass existing search engines with more comprehensive and relevant results. To differentiate itself, Cuil organizes web pages by content and displays relatively long entries and pictures for each result. It claims to have a larger index than any other search engine, with about 120 billion web pages. Cuil is managed and developed largely by former employees of Google. The company has raised $33 million in venture capital from Greylock and others.
Unlike Google, Cuil's privacy policy claims that it does not store records of users’ search activity or IP addresses.
Cuil's founders, Anna Patterson, Russell Power and Louis Monier are former Google employees, while Tom Patterson has worked for IBM and others.
