NumberEight and Carbonatix Join Forces to Revolutionize Programmatic Audio Advertising with AI-Powered Audience Curation

NumberEight, a global leader in privacy-first, ID-less data solutions, has announced a strategic partnership with Carbonatix, a pioneer in programmatic digital audio advertising. This collaboration is set to redefine audio advertising by integrating NumberEight’s AI-powered Affinity Audience solution into Carbonatix’s cutting-edge audio ecosystem—enhancing reach, relevance, and audience engagement at scale.

By leveraging NumberEight’s privacy-compliant, ID-less audience intelligence, Carbonatix will enrich its premium audio inventory, which spans direct publisher integrations across news, entertainment, and lifestyle content. Advertisers can now precisely target key demographics and interest-based segments—such as female listeners and multicultural audiences—without relying on traditional identifiers, ensuring a privacy-first approach to engagement.

Through Carbonatix’s advanced player, these audience insights seamlessly power immersive, multi-device audio experiences. Brands can deliver highly relevant ads across varied formats, whether through text-to-speech (TTS)-enabled articles on premium publishers or in-app Companion Banner Audio ads that synchronize visuals with audio. This dynamic approach maximizes impact, engagement, and brand recall, ensuring that advertisers connect with audiences in a respectful, meaningful way.
