Careers at Quantcast


Quantcast is a digital advertising company which aims to provide real-time advertising solutions and audience measurement services to marketers, advertisers and publishers.


Quantcast was founded in 2006 by Konrad Feldman (“Feldman”) and Paul Sutter (“Sutter”). In an interview with City AM, Feldman discussed how the public listing of Google stock in 2004 generated a great deal of interest in search advertising within the technology community.

This prompted Sutter to consider why targeted advertising was not attributed to browsing habits in the same way that it was being attributed to search engine history. Feldman and Sutter wished to explore this avenue further, but having no advertising experience they decided to post an advertisement on Craigslist asking to speak with people in the industry in return for $20 and a drink.

After meeting with several people, they gained an understanding of what audiences marketers sought, in terms of demographics, interests and habits. The pair began to develop a system of data collection, with tests in early 2006 identifying a number of browsing patterns. Feldman and Sutter next began designing ways to manage the data gleaned from its collection tools and provide real-time advertising solutions.

The Company attracted investors in 2007, raising $5.7 million in its series A funding round. To date Quantcast has received more than $65 million from five rounds of funding, with investors including Cisco and Polaris Partners. Quantcast officially launched its advertising solutions product in 2009 and has since added Quantcast Audience Grid to its list of services.

Key Partners

Quantcast’s partners are primarily data providers, which provide data across multiple channels, covering television, ownership information, political data, and purchase data, including companies such as TiVo Research, Oracle Datalogix, Kantar Shopcom and Experian, among others. This enables Quantcast to provide more accurate advertising solutions to its marketing clients. Until recently, Quantcast was also a partner of Facebook’s Exchange real-time advertising system where it was able to sell ad inventory, but was one of a number of companies to be let go in 2015.

Quantcast also partners with other companies operating in the digital advertising and analytics space in order to develop more efficient solutions for its clients. This includes partnerships with Israel’s Matomy Group and with tag management and data analytics firm Ensighten. Recently, the Company also launched a partnership with advertising trade association the 4As, under which they will collaborate to provide training and education resources to those within the programmatic advertising sector.

Key Resources

Quantcast’s key resources are its proprietary technology for data collection and analysis and the large amounts of information regarding user internet habits it has gathered. Despite this, there are no US patent applications registered against Quantcast’s name either as applicant or inventor.

The Company’s data and analytics partners are also important resources, helping Quantcast to provide more accurate solutions. In order to manage its data, Quantcast must also maintain reliable and secure IT infrastructure.

Cost Structure

Quantcast’s major costs come in relation to the maintenance of its IT infrastructure and its proprietary technology. This includes operating costs for data centres and the rental of server space.

Quantcast operates more than 20 offices across North America, Europe and Australia, all of which accrue fixed business costs in the form of rent and utilities.

It provides free data collection tools which enable it to track user activity across millions of tagged websites and obtain significant amounts of internet data pertaining to browsing and buying behaviours. The Company’s Quantcast Measure product allows advertisers to create a profile of the types of consumers it would like to target. Quantcast is then able to identify websites that are used by that the target demographics using its data measurement technology, taking a share of the revenue from the resulting ads sold.

Quantcast also uses data to provide targeted advertising solutions directly to publishers, on a cost per impression basis, whereby customers pay per 1,000 views of a particular advertisement, as well as selling ad inventory to advertisers via ad exchanges.
