The acquisition combines TVision's proprietary attention measurement with Viant's AI-powered programmatic platform, creating the first system where verified viewer attention directly powers real-time ad buying and optimization.
New York – Today TVision, the company measuring every second of TV and CTV viewer engagement, announced it has entered into a definitive agreement to be acquired by Viant Technology Inc. (NASDAQ: DSP), a leader in CTV and AI-powered programmatic advertising, in a transaction valued at $40 million. The deal, expected to close in Q2 2026, brings TVision's second-by-second, person-level attention data, co-viewership signals, and in-room presence measurement directly into Viant's buying platform.
The acquisition marks a significant milestone for TVision and the attention measurement category. By integrating with Viant's Intelligence Layer — alongside its Household ID and IRIS_ID — TVision's data will operate as a real-time signal within the ad buying process, enabling advertisers to plan, optimize, and measure campaigns against verified attention at the network, CTV app, show, scene, pod, and spot level. The result is a first-of-its-kind capability: attention-adjusted CPMs within an independent, buy-side-only platform free from walled garden self-attribution bias.
"TVision was built to provide a more accurate and transparent view of how people engage with television and streaming content," said Yan Liu, CEO and Co-Founder of TVision. "By joining Viant, we can bring our measurement capabilities together with real-time activation and AI-powered optimization, helping advertisers turn attention insights into superior campaign performance."
Rockefeller Capital Management served as the exclusive investment banking advisor to TVision in connection with the transaction.
