Yieldlab

Leading European premium SSP with strong positioning among top-tier German and European publishers, now operating within the Microsoft/Xandr ecosystem

Yieldlab is a Hamburg-based supply-side platform (SSP) and yield management solution founded in 2008, purpose-built for the European premium publishing market. The platform enables publishers to monetize their digital inventory through programmatic advertising, header bidding, private marketplaces (PMPs), and direct deal management. Yieldlab supports multiple ad formats including display, video, native, and mobile, and is known for its strong focus on data privacy and compliance with European regulations such as GDPR. Yieldlab serves some of Europe's largest and most prestigious publishers, offering tools for inventory management, audience data activation, and real-time bidding. Its platform integrates with major demand-side platforms (DSPs) and ad exchanges, giving publishers access to a broad pool of premium advertisers. The company has built a reputation for transparency, brand safety, and high-quality inventory curation, which differentiates it in the competitive SSP landscape. In 2019, Yieldlab was acquired by AppNexus, which was subsequently acquired by AT&T's Xandr. Following Microsoft's acquisition of Xandr in 2022, Yieldlab became part of the Microsoft advertising ecosystem. This integration has expanded Yieldlab's technological capabilities and demand access while maintaining its focus on European premium publishers. The company continues to operate as a key SSP solution within the broader Microsoft/Xandr stack.
