Quantcast is an American technology company, founded in 2006, that specializes in audience measurement and real-time advertising. The company offers public access to traffic and demographic data for millions of Web sites and detailed user insights to digital publishers enrolled in its Quantified Publisher Program. Their data centers process more than 800,000 transactions per second[4] and the company states that it produces accurate audience measurement to over 100 million web destinations. As of 2013 it was said to be one of the world's top five big data processing organisations.[5] Its headquarters is in San Francisco, with offices in New York, Chicago, London and Dublin.[6]


Quantcast was launched in 2006 by entrepreneurs Konrad Feldman and Paul Sutter.[7] Calling themselves "The World's Only Open Internet Ratings Service", Quantcast were the first rating company to rely largely on direct measurement (as opposed to the traditional panel based method pioneered by Nielsen).[8][9]

Quantcast was initially backed by $6 million in venture capital funding. In January 2008, a series B funding round raised an additional $20 million from investors Founders Fund and Revolution Ventures. The company was built on the belief that digital advertising requires reliable data to be successful, so initially the primary aim was to gather detailed insights into audience characteristics. By placing tags on websites, blogs, videos and widgets, the firm measures things like audience age and gender makeup, areas of interest and type, length and frequency of their engagement with certain types of content. This information is generally made publicly available to be used by digital publishers to accurately understand their visitors and better position themselves to advertisers.[10]

In 2010, Quantcast’s Publisher Program was the first syndicated online traffic measurement service to receive official accreditation from the Media Rating Council (MRC). Quantcast received accreditation for its site-centric data, which means the product complies with the Interactive Advertising Bureau's advertising impression and audience reach measurement guidelines.[11]

In 2013, the company acquired MakeGood Software, a Seattle-based advertising technology startup, founded in 2009, that simplifies data management and reporting for online advertising campaigns.[12] The technology was subsequently integrated with Quantcast Advertise to enhance the reporting functions available for Quantcast campaigns. This nudged the company closer towards competition in the ad effectiveness category, which includes companies like comScore.[13][14]

In 2013, the company added Measure for Mobile Apps, a tool that collects data on the usage of a publisher’s iOS and Android apps to provide a cross-platform view in its analytics service.[15] In 2014, Quantcast is acquiring Struq for an undisclosed sum.[16]
