Quantcast, a privately owned company headquartered in the US, was founded in 2006 and employs approximately 560 people. Functioning as a global ad tech company, it specializes in AI-driven real-time advertising, audience insights, and measurement solutions.
Quantcast appointed Rebecca Rosborough as Chief Marketing Officer on March 16, 2026, a move made amidst a significant expansion phase for the company and its AI-based adtech platform. Previously, on February 19, new data from Quantcast revealed that in-game advertising during the Six Nations rugby championship drove higher online engagement for two major brands, yet simultaneously sparked heavily negative social media reactions from fans during matches. This followed Quantcast's research released on February 15, which showed that while in-game advertising during the Six Nations delivered a considerable increase in online engagement for brands, the audience reaction was not always positive. Specifically, Samsung recorded a 13% increase in engagement, and Virgin Atlantic saw an 18% uplift in matches where their adverts aired during scrum-related breaks in play.
Quantcast's customers primarily consist of media and TV services and telecoms companies. Examples of Quantcast's customers include Simyo, Sky Group and Lionsgate. Quantcast has partners like Mediacom Communications.
