Viant's Strong Q4: Growth Amidst Big Competitors' Challenges
Viant reported strong Q4 and full-year 2025 results, with net income of $24.1 million (nearly double 2024) and full-year revenue of $110 million, up 22% year-over-year. CEO Tim Vanderhook said revenue would have grown 28% excluding prior-year election-driven political ad comps. Shares rose more than 10% after the report. Executives emphasized competitive pressure from large platforms (Google, Amazon, The Trade Desk) and warned about Amazon’s subsidized DSP and bundling strategies; Netflix and Roku have signed deals with the Amazon DSP. Viant is also pushing AI-based products: a new LLM-based prompt-and-response interface and an outcomes-focused AI optimization product called Outcomes, which the company says has outperformed human media buyers. Management urged caution on near-term ad formats in AI chat environments like ChatGPT/OpenAI, noting integration challenges with programmatic RTB protocols.
Viant’s strong results and new AI products matter for competitive dynamics and AI-driven media buying, but the company is relatively small compared with major platforms (Google, Amazon, The Trade Desk), limiting broader industry impact.

Viant Reports Q1 Growth, Calls Out Walled Gardens
Viant reported Q1 2026 results and highlighted strong DSP momentum while criticizing walled‑garden ad platforms. The company’s DSP revenue rose 18% year‑over‑year to $50.3 million and its GAAP net loss narrowed from $3.3 million to $2.2 million; Viant cites an adjusted net‑income metric that would show $5.5 million in profit after excluding certain costs. Executives — including COO Chris Vanderhook and CEO Tim Vanderhook — argued advertisers are shifting away from self‑attributing walled gardens (naming Amazon, Google/YouTube and Prime Video among examples) and noted large RFP activity that could drive budget gains in 2027. Analysts referenced Viant’s acquisitions (TVision, Iris.TV, Lockr) and proprietary data as contributors to valuation and future pricing power.
ViantAI Decisioning Redefines the DSP
Viant Technology is acquiring TVision Insights for $40 million ( $22.5M cash and $17.5M in Class A common stock), a deal the article says closes in April 2026. Viant will integrate TVision’s second-by-second, computer-vision and ACR-based household attention panel into its buy-side-only DSP, using attention signals to inform planning, buying, optimization and post-campaign measurement. The acquisition enables an "attention-adjusted CPM" that weights impressions by whether viewers watched, addresses co-viewing multipliers and aims to connect CTV exposure to downstream search and purchase behavior. The move complements prior Viant acquisitions (IRIS.TV for contextual targeting and Wurl integrations for FAST/scene-level placement) and is positioned to create defensible pricing for high-attention inventory such as live sports by verifying attention independently of platform self-reporting.
Ad tech earnings show mixed results, CTV growth
Digiday’s May 14, 2026 briefing reviews recent Q1 earnings across a 12-company ad tech cohort. While most firms reported revenue increases and some raised guidance, the quarter was mixed: three companies recorded year‑over‑year revenue declines and several executives flagged AI-driven changes that could affect platform stickiness and margins. AppLovin posted strong Q1 results (nearly $2 billion), Teads and Criteo reported revenue declines (7% and 6%, respectively), and Viant and others highlighted Connected TV (CTV) as a major growth driver — with Viant reporting CTV ad spend now accounts for more than half of platform spend. The Trade Desk’s $750M Q2 revenue guide was viewed as soft and pressured its stock. The article notes varied AI initiatives (ChatGPT integrations, Taboola’s AI Answer engine, PubMatic’s AI deals) but few clear examples of material AI-driven revenue yet.
