Viant Technology Inc.: what insiders have been doing
Viant Technology Inc., classified in the Media & Communication sector, is a listed company based in Irvine, United States, founded in 2020. Its insiders report their share dealings to SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 79 filings came from 10 insiders.
No insider bought on the market over the period, while 3 insiders filed 38 sales totalling €3.5M. The totals do not cover 3 filings with an undisclosed amount. At €293k, the sale published on 13 August 2026 by Madden Larry is the largest of the period (0.041% of market cap).
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
Compared with its exchange (5,808 companies, median 19 filings), a count of 79 filings is above the norm. Our records for Viant Technology Inc. go back to 2021, with no purchases and 54 sales on the open market in total. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 344.2 m USD and net income at 8.4 m USD.

About Viant Technology Inc.
Viant Technology Inc. (NASDAQ: DSP) is a U.S.-listed advertising technology company traded on the NASDAQ market in the United States. It operates in the buy-side programmatic advertising space, with a strong focus on connected TV (CTV), the open internet, and omnichannel digital media buying. From an international equity perspective, Viant stands out as an adtech platform that aims to combine automation, measurement, and optimization through proprietary identity, content, and now attention signals.
The company was founded in 1999 by Tim, Chris, and Russ Vanderhook, who remain deeply involved in the business. Viant is headquartered in Irvine, California, placing it in one of the most important technology and advertising ecosystems in the U.S. Its corporate history reflects the evolution of digital advertising from early video and audience-based buying toward today’s AI-driven, cross-screen execution and measurement.

Viant’s core business centers on its proprietary demand-side platform and related software tools that help advertisers and agencies plan, buy, activate, and measure campaigns. Key offerings include the Viant DSP, identity resolution capabilities such as Household ID and IRIS_ID, and AI-enabled decisioning tools. The company also emphasizes real-time reporting, pre-bid targeting, and campaign optimization features designed to improve media efficiency and outcomes. In practical terms, Viant is positioning itself as more than a media execution venue: it is trying to become an advertising intelligence platform.
Its competitive positioning is built on a buy-side-only model, a strong CTV orientation, and the integration of proprietary data into an AI decision layer. In a market dominated by large closed ecosystems, Viant seeks differentiation through transparency, independent measurement, and a more direct link between audience, content, and attention signals. That can be attractive to advertisers looking for scale on the open internet while retaining control over performance and measurement.
Recent developments are strategically important. In May 2026, Viant completed its acquisition of TVision Insights, a specialist in TV and CTV attention measurement. Management has said this expands the company’s intelligence layer and strengthens its capabilities across data, measurement, and activation. Viant also launched “Outcomes” in 2026, described as a fully autonomous AI-powered advertising solution, and continued to report strong CTV momentum and new commercial partnerships. Recent updates suggest that CTV is becoming an increasingly important share of advertiser spend on the platform.
For investors, Viant combines exposure to secular digital advertising growth, AI-enabled product innovation, and the expanding CTV market in the United States. The key analytical question remains whether the company can sustain growth while deepening its differentiated data and measurement stack against larger competitors and walled-garden platforms.
