Viant Technology Inc., a leader in CTV and AI-powered programmatic advertising, announced it has entered into a definitive agreement to acquire TVision Insights, the only attention measurement provider delivering second-by-second, eyes-on-screen attention, co-viewership and in-room presence for TV.

“With TVision, we are providing advertisers a true market-wide view of how their advertising performs, free from any platform’s self-attribution bias,” said Tim Vanderhook, CEO and Co-Founder of Viant.

With this acquisition, Viant strengthens its AI-powered programmatic platform by integrating TVision’s proprietary attention signals directly into its buying platform. Combined with Viant’s Household ID and IRIS_ID, TVision adds three new critical signals to Viant’s Intelligence Layer, creating a continuous feedback loop where viewer engagement flows directly into planning, buying, optimizing, and measuring advertising campaigns. This creates an unprecedented level of granularity across TV at the network, CTV app, show, scene, pod, and spot level – delivering immediate improvements in inventory valuation, bidding precision, and return on ad spend, exclusively within the Viant platform.

“Every advertising platform measures its own performance today, which makes it difficult for advertisers to understand what’s actually working. With TVision, we are providing advertisers a true market-wide view of how their advertising performs, free from any platform’s self-attribution bias. While our competitors measure themselves, Viant measures the market,” said Tim Vanderhook, CEO and Co-Founder of Viant. “Advertisers can now use attention, co-viewing and in-room signals within Viant’s AI-powered buying platform giving them unparalleled strategic advantages, including a first-of-its-kind metric: the attention-adjusted CPM.”

Television advertising today spans linear, Google’s YouTube, Amazon’s Prime Video, and streaming platforms across the open internet. Yet each platform largely measures its own performance, leaving marketers without an objective, unbiased view of how their total advertising investment actually performs. TVision’s nationally representative panel uses advanced computer vision and Automatic Content Recognition technology to capture genuine viewer engagement across this entire ecosystem — giving advertisers a single, independent view of attention and enabling them to optimize spend toward impressions that are actually seen.

“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.”

The result is the trifecta TV advertisers have long been waiting for: identity, context, and verified attention unified in one independent platform, free from the conflicts of walled garden inventory — enabling advertisers to confidently direct spend toward the ad inventory that truly performs and delivers optimal outcomes.
