Ixquick and StartPage were both mentioned, but they are one and the same. Startpage is the US 'version' of Ixquick that they put up partly to separate the US and Euro (NL) divisions. They do no crawling, relying on digesting results from Google, Bing and others. They sell advertising similar to AdWords for income. They do offer tools that let you use Google's tools anonymously. Duckduckgo uses Yandex crawlers.
