Peer39

Leading contextual intelligence provider serving major advertisers and DSPs with real-time content analysis and brand safety solutions

Peer39 is a contextual intelligence and brand safety technology company that provides semantic analysis and page-level categorization solutions for digital advertising. The company uses advanced natural language processing and machine learning to analyze web content in real-time, enabling advertisers to make informed decisions about ad placement while ensuring brand safety and suitability. Peer39's technology helps advertisers move beyond cookie-based targeting by understanding the context of content where ads appear, making it particularly relevant in the privacy-first advertising landscape. The company serves major brands, agencies, and demand-side platforms (DSPs) by providing pre-bid contextual targeting and brand safety solutions that integrate directly into programmatic advertising workflows. Peer39 has established itself as a key player in the contextual intelligence space, competing with companies like DoubleVerify, Integral Ad Science, and Oracle's Grapeshot. The company was acquired by PubliGroupe (now Publicis Media) in 2016 and operates as part of the larger Publicis Groupe ecosystem, providing contextual intelligence solutions across the holding company's media buying operations and to external clients.
