NumberEight & SoundCast Partner to Power Smarter, Privacy-First Podcast Advertising Across Europe
"As part of its continued investment in data-driven audio solutions, SoundCast is integrating NumberEight's predictive audience technology into its infrastructure, activating NumberEight's Affinity Audiences across its inventory to unlock more effective and privacy-first podcast advertising across the continent. Early results show a 132% increase in podcast addressability and a 78% boost in targeting accuracy compared to legacy IP-based methods."
"According to the Global Podcast Advertising Compass 2025, Europe remains significantly under-monetised relative to its high podcast engagement, particularly in markets such as France and Germany. One of the core challenges has been limited and fragmented audience data, which has restricted scalable and effective targeting."
"NumberEight's Affinity Audiences are built using contextual content signals and demographic modelling powered by privacy-safe engagement data. These segments are now available across SoundCast's inventory, with no reliance on personal identifiers."
NumberEight, an ID-less audience intelligence company, has partnered with SoundCast, an audio monetisation platform, to integrate predictive audience technology into podcast advertising infrastructure. The integration activates NumberEight's Affinity Audiences across SoundCast's inventory, delivering privacy-first targeting without personal identifiers. Early results demonstrate significant improvements: 132% increase in podcast addressability and 78% boost in targeting accuracy compared to legacy IP-based methods. European podcast markets remain under-monetised despite high engagement, particularly in France and Germany, due to fragmented audience data. The partnership addresses this gap by enabling scalable activation of high-value audiences across international podcast networks. NumberEight's Affinity Audiences use contextual content signals and demographic modelling powered by privacy-safe engagement data, offering over 100 audience segments including affluent consumers, business leaders, and Gen Z audiences.
