NumberEight, the leading ID-less audience intelligence company, has partnered with SoundCast, a leading audio monetization platform connecting premium international podcast publishers across Europe and the US with global advertisers.
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 undermonetized 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. This partnership addresses that gap by integrating NumberEight’s predictive audience technology into SoundCast’s audio monetization and targeting stack, enabling scalable activation of high-value audiences across its international podcast network.
NumberEight’s Affinity Audiences are built using contextual content signals and demographic modeling powered by privacy-safe engagement data. These segments are now available across SoundCast’s inventory, with no reliance on personal identifiers.
As advertisers plan for Q2 campaigns, brands can now engage relevant, high-impact audiences, including:
Affluent Consumers
Business & Finance Leaders
Small Business Decision Makers
Football World Cup Fans
Gen Z
…and +100 aduiences available for upcoming seasonal and always-on activations.
“As podcast ad demand continues to grow in 2026, brands need solutions that deliver both effectiveness and responsibility,” said Abhishek Sen, CEO and Co-Founder at NumberEight. “Together with SoundCast, we are making podcast targeting more accurate, more scalable, and fully privacy-safe across Europe and beyond.”
“The evolution of digital audio requires both premium environments and advanced data capabilities. By embedding audience intelligence into our audio stack, SoundCast reinforces its position as a scalable, data-driven monetization partner for publishers and a high-performance channel for agencies worldwide,” said Jean-Baptiste Quenum, Co-Founder and COO at SoundCast.
The partnership is now live and available for immediate activations across SoundCast’s podcast inventory.
