Online traffic and analytics company, Quantcast has raised a hefty $27.5 million in Series C financing.  The round was co-led by Cisco and Polaris Venture Partners.  Previous investors Revolution Ventures and Founders Fund also participated, bringing Quantcast's total funding to $53.2 million.  

The San Francisco-based startup has built a platform focused for the advertising industry, which according to Quantcast offers, "a standardized means to measure, organize, buy and sell real-time audiences, all based on the distinctive characteristics of a marketer's proprietary customer data."  Some other companies playing in this space include Compete and Alexa.

Cisco's SVP and GM Dan Schneiman commented on Monday in a blog post saying, "The digitization of media content is causing wholesale changes to the business and experience of media and advertising. We believe an intelligent network is the best platform for delivering high-value experiences in the digital age and are always working to address the needs of our customers."

Quantcast said it has already attracted some high-profile clients including NBC Universal, Time Inc., Hulu, CBS, Fox News, ABC and Bloomberg and its solutions are being used for 10 million Websites.  

The company said it would use the new round to support the rapid adoption of its Quantcast Media Program which was launched last year in June.
