RhythmOne

Mid-tier full-stack programmatic platform with particular strength in video, connected TV, and cross-screen advertising prior to acquisition by Tremor International.

RhythmOne was a digital advertising technology company that provided programmatic advertising solutions across multiple screens and formats, including video, display, mobile, and native advertising. The company operated a demand-side platform (DSP), supply-side platform (SSP), and data management capabilities, positioning itself as a full-stack programmatic partner for both advertisers and publishers. Its YuMe acquisition in 2017 significantly expanded its connected TV and video advertising capabilities, making it a notable player in the premium video and cross-screen advertising space. Founded as Blinkx, a video search and advertising technology company, the company rebranded to RhythmOne in 2017 to reflect its evolution into a broader programmatic advertising platform. RhythmOne built a reputation for brand safety, viewability, and audience targeting, leveraging its proprietary data and technology stack to deliver measurable results for advertisers. The company served a wide range of clients including Fortune 500 brands, agencies, and independent publishers. In 2019, RhythmOne was acquired by Tremor International (formerly Tremor Video), creating a combined entity with significant scale in programmatic video and connected TV advertising. Following the acquisition, the RhythmOne brand was gradually absorbed into Tremor International's portfolio, and it no longer operates as a distinct standalone entity. The deal was valued at approximately $176 million and helped Tremor International expand its publisher relationships and data capabilities substantially.
