World-leading Automotive Advertiser Taps NumberEight for Breakthrough Podcast Targeting

A recent campaign for a luxury automotive brand has proved the power of ID-less podcast targeting. Using NumberEight’s Affinity Audiences, activated through The Trade Desk, the campaign delivered exceptional performance—achieving scale, control, and privacy-safe precision in a category that demands excellence.

This campaign is one of the first to benefit from NumberEight’s collaboration with Barometer, the leading brand suitability and contextual targeting partner for audio. The partnership enables seamless access to NumberEight’s full suite of podcast-specific Affinity Audiences—pre-curated, ID-less, and now available directly within The Trade Desk, one of the industry’s most trusted demand-side platforms.

“We ran a campaign for a luxury car brand using NumberEight audiences on The Trade Desk, and the results so far have been extremely promising,” said Kym Treasure, Founder & CEO of Audacia Audio, based in Sydney. “This integration gives us the control and scale we need to deliver premium campaigns in podcasting—without compromising on privacy.”

Solving podcast advertising’s toughest challenge

Podcasting has long faced a data scarcity problem. Without cookies, device IDs, or IP addresses (which have their own accuracy limitations), advertisers have struggled to reach relevant audiences at scale. NumberEight solves this by combining anonymized first-party data with advanced machine learning and natural language processing to analyze podcast content signals—unlocking rich audience insights without ever relying on personal identifiers.

With 95%+ podcast coverage across 200+ countries and 28+ languages, advertisers can now confidently target high-value audiences around the world.

Popular segments include:

• Election Season Engagement
• Football World Cup Fans
• Good Hang with Amy Poehler Lookalike
• Business & Finance Leaders
• Fitness Enthusiasts

These audiences are already powering high-performing campaigns across retail, CPG, automotive, tech, and entertainment.

“With this integration, we’re making it radically easier for podcast advertisers to reach the right listeners with the right message,” said Abhishek Sen, CEO of NumberEight. “Our Affinity Audiences are built for performance, privacy, and global scale—everything podcast advertising has been missing.”

“We’re proud to partner with NumberEight to make their powerful, privacy-safe audiences accessible through The Trade Desk,” added Tamara Zubatiy, Co-Founder and CEO of Barometer. “As advertisers look for high-performing targeting solutions in the post-ID era, this integration marks an important step toward unlocking the true potential of podcasting at scale.”

With global reach, turnkey activation, and privacy-first design, NumberEight’s Affinity Audiences help agencies and brands unlock incremental podcast reach- faster, safer, and smarter.
