DoubleVerify
DoubleVerify measures over 8.3 trillion media transactions a year, giving brands independent verification of digital-ad quality. Led by CEO Mark Zagorski.
DoubleVerify
Founded in 2008, DoubleVerify emerged as a verification layer separating legitimate digital impressions from fraud and non-viewable inventory. Under CEO Mark Zagorski, the firm evolved from a pre-bid targeting tool into a media-effectiveness platform whose measurement data now underpins spending decisions across the open web, social media, commerce media networks, and connected TV. The core strategy centers on a dual capability: superior measurement and dynamic activation. DoubleVerify's AI-driven analytics identify invalid traffic, assess viewability, and classify brand-suitability risk across channels. That intelligence then feeds automated bidding engines that shift spend toward inventory proven to drive advertiser outcomes. Asset classes span programmatic display, video, and CTV; the firm also offers an integrated attribution suite — DV Rockerbox — that combines multi-touch attribution with media-mix modeling and incrementality testing. Confirmed clients include TikTok and Newsweek, which cited DoubleVerify's tools as essential for validating campaign effectiveness and improving publisher-side inventory quality. Public ownership provides scale visibility. DoubleVerify trades on the New York Stock Exchange under ticker DV, reporting 28% year-over-year revenue growth to $656 million in full-year 2024 (per the firm, 2025). The headcount exceeds 1,000 employees globally. No adjacent philanthropic vehicles or family-office structures are disclosed — the firm operates as a pure-play public company serving both buy-side and sell-side participants in the digital supply chain. Structurally, DoubleVerify's independence is its differentiator. Unlike measurement tools embedded inside walled gardens or ad-buying platforms, DoubleVerify sits outside those conflicts — its verification tag fires across publisher sites, social feeds, and CTV apps regardless of the media owner. That neutrality positions the platform as a common currency for brand-safety and performance data in a market where advertisers increasingly demand third-party proof that their budgets reached real humans in suitable environments.

Frequently asked questions
Who runs DoubleVerify and how long have they been in place?
Mark Zagorski has been CEO since August 2020. He joined DoubleVerify after serving as CEO of Telaria, a connected-TV ad platform, and previously led eXelate, a data-management firm sold to Nielsen. His tenure has coincided with DoubleVerify's expansion from fraud verification into a full media-effectiveness platform.
How does DoubleVerify make money?
DoubleVerify charges advertisers a fee based on the volume of media impressions it measures. As a public company (NYSE: DV), it reports substantially all revenue through enterprise contracts with brands, agencies, and platforms that need independent verification of viewability, fraud, and brand suitability across digital channels.
What channels does DoubleVerify's platform cover?
Coverage spans the open web, social media platforms, commerce media networks, and connected TV. The firm cites specific integrations with TikTok, where advertisers use its tools to validate campaign effectiveness, and with publishers like Newsweek, which deploys DoubleVerify's publisher suite to improve inventory quality and reporting.
Is DoubleVerify a technology company or a media company?
DoubleVerify is a technology company built on a media-measurement software platform. It does not own or sell media inventory. Its AI-driven software analyzes content and identifies fraud at the point of impression, then enables automated bidding adjustments — a model closer to enterprise SaaS than to an agency or ad network.
How large is DoubleVerify's headcount and what is its scale?
The firm employs more than 1,000 people as of early 2025. It measures over 8.3 trillion media transactions per year across the open web, social media, commerce media networks, and CTV — a volume that makes it one of the largest independent measurement platforms in digital advertising.
What is DV Rockerbox and how does it fit into the product suite?
DV Rockerbox is DoubleVerify's attribution and measurement system, acquired through the purchase of Rockerbox in 2024. It combines multi-touch attribution, media-mix modeling, and incrementality testing to help advertisers understand how their spending across channels contributes to outcomes, rather than relying on any single attribution methodology.
Who are DoubleVerify's main competitors?
The primary competitor is Integral Ad Science (IAS), another independent verification platform. Oracle Moat previously competed in this space but ceased operations in September 2024 (per Oracle, 2024). Walled-garden measurement tools from Google, Meta, and Amazon offer some overlapping functionality, but DoubleVerify positions itself as a neutral, cross-platform alternative.
