Dapper lets users extract and structure data from around the web, and then create useful services based around this structured information. For example, Dapper allows users to create an RSS feed based on any web site, even if it's not theirs, or create Flash widgets that display results from queries of specific data sets. Essentially, Dapper allows users to create an API for any website or service, and easily create mashups using it. In addition, Dapper has preempted intellectual property concerns by creating a system for content owners to easily control how their content is used by others on the Dapper service.
Dapper has applied their underlying technology to the display advertising industry, allowing advertisers to create dynamic ads that incorporate content and functionality from their website, combining it with content from publisher sites. For example, Dapper powers ads in the travel vertical that bring back live hotel availabilities for cities that a user is reading about or searched for earlier.
