ShopWiki is one of the most creative, intuitive concepts I have ever seen spun from the comparison shopping engine business model. Their crawler based CSE is smart, powerful and capable of including products from nearly every merchant seller online (given the site is crawler friendly). ShopWiki is also currently the most recognized shopping engine in existence that utilizes the power of user generated content through their built-in wiki platform.

ShopWiki was originally founded by two ex-DoubleClick execs, Kevin Ryan and Dwight Merriman, and Eliot Horowitz in 2005. Since launch, ShopWiki has continued on their goal to find and index every possible offer by a merchant that can be purchased online. ShopWiki is an advanced shopping crawler, product engine, wiki or gift guide, social community and much more. They currently even offer user submitted shopping video content and product reviews.
