Turn

Mid-tier independent DSP and DMP competing with Google DV360, AppNexus, and The Trade Desk before acquisition

Turn was a leading independent demand-side platform and data management platform that enabled advertisers and agencies to plan, execute, and optimize digital advertising campaigns across display, video, mobile, and social channels. Founded in 2004 and headquartered in Redwood City, California, Turn built a reputation for its real-time bidding infrastructure, audience data capabilities, and cross-channel campaign management tools that competed directly with major DSPs from Google, The Trade Desk, and AppNexus. Its unified platform allowed marketers to manage audience segments, activate data, and measure campaign performance from a single interface. In 2017, Amobee — the advertising technology subsidiary of Singapore telecommunications giant Singtel — acquired Turn for an enterprise value of approximately $310 million. The acquisition was a strategic move to bolster Amobee's programmatic advertising capabilities and expand its data-driven marketing platform. Turn's technology, particularly its DMP and real-time bidding infrastructure, was integrated into Amobee's broader suite of advertising solutions, which already included social and digital advertising tools following Amobee's earlier acquisition of Kontera and other assets. Following the acquisition, Turn's brand and distinct identity were gradually absorbed into Amobee's unified platform. Amobee itself was later divested by Singtel and rebranded as Tremor Video's parent company Tremor International acquired it in 2022, further consolidating the technology stack. Turn's legacy lies in its pioneering role in programmatic advertising and cross-channel data management during a formative period in the AdTech industry.
