Audion and RedCircle Unite to Expand Global Podcast Advertising Across Europe and the U.S.
The global podcast economy is entering an unprecedented phase of growth — and two major industry forces are joining together to shape the next chapter. Audion, the European audio technology leader, and RedCircle, one of the most influential podcast advertising platforms in the United States, have formed a strategic partnership designed to unlock a new era of international monetisation and large-scale advertising solutions.
This collaboration stands to reshape the way brands, agencies, and creators approach podcast advertising across borders — driving new revenue, enhancing programmatic access, and streamlining multiregional campaign execution in ways the industry has long awaited.
A Partnership Built for the Future of Global Audio Advertising
Podcasting has matured into a multi-billion-dollar global industry, with advertisers increasingly seeking seamless solutions that allow them to scale campaigns beyond their home markets. Audion and RedCircle’s newly announced partnership answers this need with a direct integration designed to connect creators, advertisers, and marketplaces across continents.
With this agreement, the two companies will merge parts of their curated podcast marketplaces into an interoperable ecosystem that:
Widens monetisation routes for podcasters in Europe and the U.S.
Expands premium ad inventory available to brands
Allows buyers and sellers to transact across borders with low friction
Supports programmatic and host-read advertising at scale
In effect, this is a plug-and-play infrastructure that removes long-standing geographic friction in the podcast supply chain — finally giving creators global commercial reach and advertisers streamlined access to international audiences.
What the Integration Means for Advertisers and Podcasters
1. Instant Access to Transatlantic Demand
By connecting RedCircle’s creator marketplace to Audion’s European programmatic demand, U.S. podcasters can now instantly tap into lucrative European advertising budgets. At the same time, European brands gain immediate access to thousands of high-quality American shows hosted on RedCircle.
2. New Premium Inventory for European Advertisers
European advertising buyers will now have access to expanded premium podcast inventory — something that has been historically difficult due to fragmented rights, market barriers, and inconsistent publisher access.
3. Multi-Country Advertising Campaigns
Using the newly unified infrastructure, major brands can launch and manage advertising campaigns across multiple countries through a single pathway. This includes:
Pan-European campaigns
Transatlantic campaigns
U.S.-to-Europe scaling
Europe-to-U.S. audience expansion
This multicountry capability is particularly valuable for global brands that prioritize consistent messaging and scalable budget efficiencies.
Why This Partnership Matters Now
The timing of the Audion–RedCircle partnership aligns with several major industry trends:
Global Podcast Listening Continues to Surge
Recent years have seen podcast audiences expand rapidly in the U.S., Europe, and emerging markets. Cross-border content discovery has become seamless, thanks to universal platforms and multilingual audiences.
Advertisers Demand More Streamlined Cross-Market Solutions
Brands are increasingly running international campaigns but have long been challenged by:
Fragmented marketplaces
Varying regulations
Uneven publisher access
Complex multi-country buying systems
This integration simplifies these challenges into a single pathway.
Creators Seek New Revenue Opportunities
Podcasters — especially mid-tier and independent creators — are under increased pressure to diversify revenue streams as competition intensifies. This partnership offers them:
Access to new continental markets
Larger brand budgets
Increased fill rates
More competitive CPMs
Statements from Industry Leaders
Arthur Larrey, Co-Founder of Audion
“RedCircle offers premium podcasting inventory across thousands of shows. This new partnership reflects the growing trend for global podcast networks to seek simplified, scalable access to monetisation beyond their core markets, while reinforcing Audion’s position as a leading podcast marketplace connecting premium international supply with strategic demand.”
Larrey’s comments highlight the industry’s growing need for globalised, frictionless solutions — a direction Audion has aggressively pursued as part of its mission to build Europe’s most advanced audio advertising ecosystem.
Jeremy Lermitte, Co-Founder & COO of RedCircle
“RedCircle looks for trusted advertising partners to support revenue growth for our creators and podcasters; we selected Audion for its ability to connect supply to premium European demand without any technical constraints, which gives us seamless access to advertiser demand in Europe. This move supports our mission to help brands scale their host-read and programmatic advertising strategies.”
Lermitte underscores RedCircle’s commitment to creator-first monetisation, suggesting that this enhanced access to European buyers will significantly raise earning potential for podcasters.

Independent creators, in particular, are likely to see substantial gains as their shows become available to more international advertisers.
The Globalisation of Podcasting: What’s Next?
Podcasting is no longer a local or regional medium. The convergence of audiences, platforms, and advertisers has marked the beginning of a fully global audio marketplace.
The Audion–RedCircle partnership is a major signal of where the industry is heading:
Unified advertising networks that span continents
Marketplace consolidation for better efficiency
Interoperable ecosystems replacing isolated regional systems
Creators building global communities rather than local followings
Advertisers leveraging worldwide reach with streamlined buying tools
More partnerships like this can be expected as the industry pushes toward a borderless audio economy.
A Milestone for 2025 — and a Roadmap for 2030
By aligning two major players from Europe and the United States, this collaboration lays the foundation for a truly globalised podcast supply chain. It offers a model the industry may follow over the next decade, especially as podcasting becomes deeply integrated with:
Voice-activated devices
Smart speakers
Connected car ecosystems
AI-driven content recommendations
Cross-media advertising networks
Audion and RedCircle’s partnership not only reflects the state of podcasting in 2025 — it shapes what the ecosystem may look like by 2030.
