Internet ratings site Quantcast has raised $20 million in second-round venture financing from Founders Fund and Polaris Venture Partners. The funding will be used to help expand its online measurement
Quantcast's system combines data from panel-based surveys and Web publishers' server logs to provide detailed profiles of Web site audiences. So far, some 20,000
publishers are using the company's free service, including Fox, CBS and Belo Corporation. Quantcast plans to eventually make money by matching advertisers with target audiences, in effect creating an
audience search engine.
In connection with the new investment, Ken Howery, a managing parter at Founders Fund, and Mike Hirshland, a general partner at Polaris Venture Partners, will join
Quantcast's board of directors.
