Zemanta is the world's first multi-channel demand-side platform built for engagement and performance. Traditional programmatic advertising platforms are built to serve impressions but Zemanta has pioneered the technology that empowers trading desks to show actual return on ad spend. Zemanta helps advertisers break free from reach and frequency metrics by determining which placements and creatives lead to the right users engaging with their ads and websites. This unique approach offers advertisers the opportunity to capture true consumer engagement, deliver wanted outcomes, and return on ad spend. Through advanced AI and automation, Zemanta empowers advertisers to buy advertising that is optimized for engagement and performance, making the most of every advertising dollar spent across Display, Video, and Native placements on the open web. Clients include WPP, Omnicom, Publicis Groupe, IPG, Dentsu, Havas, and many others. The company was founded in 2007 and is part of Outbrain, the leading recommendation platform for the open web.
