How we got started

We didn’t quite start in a garage, but with a great idea. In 2006, we wanted to address the poor online advertising experience that the industry was facing. Advertising beyond search was similar to the proverbial “finding a needle in the haystack.” The major internet giants controlled data and there was no way to reach audiences with clear and relevant consumer interest data with any type of accuracy or resolution.

Our approach was to work with publishers and advertisers on assembling one of the world’s largest live data sets and use quantitative mathematical approaches–AI and machine learning–to make sense of internet consumption data. As a result, advertising works better for them as well as consumers. Our aim is to level the playing field so everyone benefits from a free and open internet. And, today, the Quantcast Platform is a model for the future of advertising.

We love numbers. We are quants after all.
