Budapest-based adtech firm Ads Interactive is making a bold move in Europe’s programmatic landscape. The company has become the first in Hungary to offer domestic advertisers direct access to premium German header bidding inventory, thanks to new partnerships with two major players in the DACH region: Ströer and Gravite.
The announcement follows the recent opening of Ads Interactive’s German office and marks a significant milestone in its international expansion.
Gateway to the German Internet
Among the new partners is Ströer, one of Germany’s largest digital media groups. Its reach spans more than 80% of German internet users, supported by a portfolio of 1,000+ websites, including high-traffic domains like t-online.de, sport1.de, and giga.de.
Also joining the effort is Gravite, a globally respected mobile programmatic provider known for large-scale, high-quality inventory and robust data-driven ad delivery across markets.
Together, these partnerships give Hungarian advertisers and media agencies unprecedented access to premium ad placements in Germany’s most trusted online content environments.
Leveling the European Ad Market
“For export-focused Hungarian and regional brands, this is a game changer,” said Harald Stück, CEO of Ads Interactive Hungary. “Until now, premium Western European inventory was largely out of reach for advertisers in Central and Eastern Europe. This changes that.”
Stück sees the move as a cornerstone of Ads Interactive’s mission: delivering measurable, high-impact ad opportunities beyond domestic borders.
Why Header Bidding Matters
The core technology behind the expansion is header bidding—a real-time auction model that gives advertisers access to multiple publishers at once, creating a more competitive and transparent ad-buying environment.
“Header bidding enables better viewability, lower costs, and stronger targeting—especially on mobile,” said Balázs Buza, Director of Innovation & Marketing at Ads Interactive. “It also helps eliminate the traditional disadvantages advertisers faced when relying solely on legacy programmatic methods.”
Strategic Implications
The partnership positions Ads Interactive as a regional innovator in programmatic advertising. It also reflects broader adtech trends: as brands in smaller markets seek global reach, access to premium cross-border inventory becomes a strategic imperative.
Moreover, the expansion into Germany places Ads Interactive in direct competition with larger Western European DSPs and media networks—signaling Hungary’s growing influence in the European adtech ecosystem.
Bottom Line
With these deals, Ads Interactive isn’t just opening new ad inventory. It’s creating a pipeline for Hungarian and Central European brands to punch above their weight in Western markets—backed by premium partners, competitive pricing, and cutting-edge auction technology.
