Ligatus

Was the leading native advertising platform in Europe by monthly impressions prior to its acquisition by Outbrain in 2019

Ligatus was a Cologne, Germany-based native advertising platform founded in 2005 and owned by Gruner+Jahr, a subsidiary of Bertelsmann. At its peak, Ligatus was the dominant native advertising network in Europe, delivering over 37 billion monthly impressions across a broad network of premium publishers. The platform specialized in content recommendation, native display, and performance-driven advertising formats tailored to European markets, with a strong emphasis on brand-safe, contextually relevant ad placements. In February 2019, Outbrain acquired Ligatus from Gruner+Jahr, positioning the combined entity as a major force in European native advertising. The acquisition was framed as a strategic move to expand Outbrain's publisher footprint and advertiser reach across the continent, merging Ligatus's deep European publisher relationships with Outbrain's global technology infrastructure. However, following the acquisition, Outbrain moved to consolidate its platforms, and by 2020 the Ligatus brand had been sunset, with its technology, publisher relationships, and team absorbed into Outbrain's broader network. Ligatus's legacy endures through its contribution to the maturation of native advertising in Europe. It helped establish content recommendation and native formats as mainstream monetization tools for European publishers, and its publisher network formed a meaningful part of Outbrain's European expansion. Outbrain itself subsequently rebranded as Teads following a later merger, making Teads the ultimate successor entity to the assets and relationships that Ligatus helped build.
