Our approach to exchange efficiency
Unparalleled scale
We process 500 billion requests daily and 1 million transactions per second—more than even the New York Stock Exchange. This level of scale demands efficiency, which translates to maximized yield for media owners and broader reach with higher win rates for buyers—all at a lower cost.
Predictive intelligence engine
Our predictive intelligence engine allows us to accurately and efficiently curate the most relevant content and audiences. We invest in machine learning capabilities to help ensure we send the most valuable impression opportunities to DSPs, and to enhance signaling and price guidance for smarter buyer decisioning.
Modern architecture and advanced infrastructure
Recently rebuilt from the ground up, our platform provides an efficient, unified experience across every channel. Our modernized architecture reduced our power per auction by 40% while ensuring flexibility and adaptability for our customers.
We own and operate data centers around the world to minimize latency and ensure a seamless consumer experience. This gives us full control over our auction capacity and bid response speeds, creating operational efficiencies that boost performance and lower costs across the supply chain.
