Forged from both sides of the ad ecosystem.
Most agencies pick a side. We built Brokkr to master both — with two decades of publisher relationships that show us exactly where inventory sits, what it's worth, and how to turn it into performance for advertisers.
We exist to close the gap between what advertisers pay and what publisher inventory is actually worth.
Digital advertising is broken by fragmentation. Advertisers struggle to reach audiences efficiently. Publishers leave revenue on the table. The two sides operate in silos, each with incomplete visibility into the other.
Brokkr was built to close that gap. Named after the Norse craftsman who forged the most powerful weapons in existence, we operate on both sides at once: in partnership with M-DSP, we plan and execute performance-driven campaigns for advertisers; through Children of Sun, we work inside our publishers' technology, operations, and strategy to extract the highest possible value from their inventory.
That publisher-side craft is the same one that helped scale Kleinanzeigen.de's advertising business past €100M in revenue, and that we've since brought to publishers including Swiss Marketplace Group, Wallapop, ImmoScout, and Immowelt. Once a year, both sides of that world meet at the Pr0grammat1c Summit, the industry gathering we produce for the people building programmatic advertising's next chapter.
Precision over volume
We don't chase scale for its own sake. Every campaign, every integration, every optimization is engineered for measurable impact.
Transparency by default
No black boxes. Our clients see exactly where their money goes and exactly what it returns. Full visibility is non-negotiable.
Technology as leverage
We build proprietary tools because off-the-shelf solutions weren't built for the problems we solve. Technology is our competitive edge.
Both sides win
The best outcomes happen when advertiser performance and publisher yield are optimized together. We're the only agency that engineers for both.
Built by practitioners,
not theorists.
