Turn

Marketing · Redwood City, United States · Founded 2004

Develops and provides an advertising technology platform for marketers, brands, and agencies MoreLess

Turn was a digital advertising technology firm founded in 2004 by David C. Smith, a computer science PhD, and Bill Demas, who later became the CEO. Smith's technical background was instrumental in developing the company's core technology, while Demas brought extensive experience from the technology and media sectors to guide the company's business strategy.

The company established itself in the programmatic advertising space, providing a comprehensive demand-side platform (DSP) for advertisers. Its core offering was the Turn Marketing Platform, a unified system designed for advertising agencies and large enterprises. This platform allowed clients to manage their digital advertising campaigns from a single interface, integrating audience planning, media buying across various channels, and real-time performance analytics. Turn's business model was centered on charging fees for transactions and usage of its platform, generating revenue from the advertising spend managed through its system.

A key feature of the Turn Marketing Platform was its ability to offer real-time insights and analytics, enabling marketers to make data-driven decisions on the fly to optimize their campaigns. The platform also provided access to an extensive ecosystem of over 150 integrated marketing technology partners, offering flexibility and enhanced capabilities to its users. In 2017, after raising significant venture capital, Turn was acquired by Singtel-owned Amobee, a move that integrated Turn's demand-side platform with Amobee's broader marketing technology stack, effectively marking the conclusion of Turn's journey as an independent entity.
