Founded2004

RhythmOne PLC was a digital advertising technology company that connected audiences with brands through premium content across devices. Specializing in programmatic advertising, RhythmOne offered a unified platform for buyers and sellers, encompassing video, display, mobile, and connected TV advertising. The company provided data-driven targeting, brand safety measures, and advanced analytics to optimize campaign performance. In 2019, RhythmOne was acquired by Taptica International, which later rebranded to Tremor International and subsequently to Nexxen, integrating RhythmOne's technology and services into its broader ad tech stack.
