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 recently sponsored B&T's breakfast session on April 1, 2026, where senior marketers discussed the marketing industry's emphasis on optimization, questioning if efficiency itself might be a problem rather than a solution. This followed the departure of Andrew Double, a veteran global sales leader from Quantcast, who joined AI marketing startup Adora as its Vice President of Revenue on March 26, 2026, after building revenue organizations across three continents. Earlier, on March 16, 2026, Quantcast appointed Rebecca Rosborough as its Chief Marketing Officer, a move occurring amidst a period of 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.
