NumberEight, a global leader in privacy-first, ID-less data solutions, is excited to announce a strategic partnership with Carbonatix, a pioneer in programmatic digital audio advertising. 

This collaboration integrates NumberEight’s Affinity Audience solution into Carbonatix’s advanced audio ecosystem—powering both web-based text-to-speech (TTS) solution and immersive in-app Companion Banner Audio formats. to unlock incremental reach and deeper audience relevance—enabling advertisers to connect with listeners more effectively and at greater scale.

The partnership enables Carbonatix to enrich its premium audio inventory—including direct publisher integrations across news, entertainment, and lifestyle—with curated audience segments powered by NumberEight’s AI-driven Affinity Audiences. Using compliant, ID-less data, advertisers can now reach key demographics and interest-based groups—such as female listeners and multicultural voices—with greater precision and resonance.

Through Carbonatix’s intuitive player, these insights come to life across immersive, multi-device audio experiences. Advertisers can run campaigns across diverse formats and lengths—whether streamed through TTS-enabled articles on leading publishers or delivered in-app with synchronised companion banners—both designed to maximise impact and engagement.  By combining emotionally relevant creative with privacy-first, ID-less audience intelligence, brands can connect with the right people—respectfully, meaningfully, and at scale.

“Our collaboration with Carbonatix marks a turning point for how programmatic audio is curated and delivered,” said Abhishek Sen, CEO of NumberEight. “By layering our privacy-first, ID-less audience insights onto Carbonatix’s rich inventory, we’re helping brands engage more meaningfully —delivering relevant audio ads in contextually rich environments while maintaining user trust.”
