About

A growing challenger in contextual intelligence and ad verification, competing against established players like DoubleVerify and Integral Ad Science, with expanded capabilities via the Adloox acquisition

Peer39 is a contextual data platform that helps advertisers target and measure campaigns. Its offerings combine contextual intelligence, brand suitability, and authenticated, program-level CTV targeting with pre-bid and post-buy solutions for programmatic buyers. Peer39 recently acquired ad verification system Adloox from Scope3, a move intended to advance its capabilities within the walled gardens of Meta and Google. This integration positions Peer39 to compete more directly against third-party ad verification and measurement platforms such as DoubleVerify and Integral Ad Science.
