Sizmek

Former leading independent ad tech platform before bankruptcy and asset sale in 2019

Sizmek was a prominent independent advertising technology company that provided an integrated advertising platform for buy-side marketers and sell-side publishers. The company offered solutions spanning creative optimization, data management, programmatic buying, and campaign analytics across display, video, mobile, and social channels. Sizmek was formed through the merger of MediaMind and PointRoll in 2014 under Vector Capital ownership, and became one of the largest independent ad tech platforms before its eventual acquisition and dissolution. In 2019, Sizmek filed for bankruptcy and its assets were subsequently sold off to multiple buyers. Amazon Advertising acquired Sizmek's dynamic creative optimization (DCO) and creative management platform assets, while Zeta Global acquired the Sizmek DSP (demand-side platform). This marked the end of Sizmek as an independent entity, though its technology and products were integrated into the acquiring companies' platforms. At its peak, Sizmek served major brands and agencies globally, processing billions of ad impressions and managing substantial advertising spend across digital channels.
