Sortable

A well-regarded Canadian publisher monetization platform, now integrated into Freestar's broader publisher solutions ecosystem

Sortable, now part of Freestar following its acquisition, is a Canadian AdTech company headquartered in Kitchener, Ontario, that provides digital publishers with a comprehensive suite of tools to maximize their advertising revenue. The platform specializes in header bidding technology, programmatic advertising management, and real-time analytics, enabling publishers of all sizes to optimize their ad inventory and compete effectively in the open programmatic marketplace. Sortable's technology aggregates demand from multiple ad exchanges and demand-side platforms, helping publishers achieve higher CPMs and fill rates through intelligent yield optimization. Freestar, a leading publisher monetization platform backed by ABRY Partners, acquired Sortable to strengthen its publisher-focused offering and expand its footprint in the Canadian market. The acquisition brought together Sortable's robust analytics and header bidding capabilities with Freestar's established network of premium demand partners and managed services, creating a more comprehensive solution for independent publishers seeking to compete with larger media companies. Prior to its acquisition, Sortable had built a strong reputation in the publisher monetization space by offering transparent, data-driven tools that gave editorial teams and revenue managers granular visibility into ad performance. Its analytics dashboard was particularly well-regarded for surfacing actionable insights around viewability, latency, and revenue attribution. As part of Freestar, Sortable's technology and expertise continue to serve digital publishers looking to grow sustainable ad revenue without sacrificing user experience.
