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.
On April 6, 2026, Dan Lee, Quantcast's vice-president of product management, highlighted marketers' increasing demand for tangible advertising outcomes over superficial metrics. Lee, who joined Quantcast eight months prior from Nielsen, made these comments while meeting clients in Sydney. Earlier, on April 1, Quantcast sponsored B&T’s latest breakfast session, where senior marketers debated the industry's focus on optimization and the potential for an "efficiency illusion." This followed the departure of Quantcast sales veteran Andrew Double, who joined AI marketing startup Adora as VP of Revenue on March 26, after building revenue organizations across three continents for Quantcast. Previously, on March 16, Quantcast appointed Rebecca Rosborough as Chief Marketing Officer, a move made amid expansion for the company and its AI-based adtech platform.
Quantcast's customers primarily consist of telecoms and media and TV services companies. Examples of Quantcast's customers include Lionsgate, Simyo and Sky Group. Quantcast has partners like Mediacom Communications.
