Mark Zagorski, CEO of DoubleVerify, discussed the company's pending $2.15 billion acquisition by Nielsen, announced in August 2026 and expected to close by the first quarter of 2027. In an interview, he reflected on advertising's evolution over the past two decades, saying programmatic buying shifted media transactions from humans to machines. He stated that measurement has become cross-platform, actionable, and tied to outcomes such as sales, and that verification is moving toward more granular and consistent data. He also mentioned an expanded relationship with TikTok, including measuring more media types and offering pre-bid solutions to avoid certain content. In a separate podcast appearance, Zagorski discussed DoubleVerify's AI engine, DV Neura, and tools such as "Slop Stopper," which he said helps advertisers avoid low-quality AI-generated content, including on YouTube. He cited a statistic that 70% of images on social media are AI-produced and reported a 140% increase in connected TV fraud in the first quarter, attributing part of that growth to AI's ability to generate fraudulent websites and apps. He described DV Neura as providing speed, confidence, and control for advertisers, and advised young people entering the industry to remain flexible and use AI as a tool, noting that some current jobs may be replaced by AI while new roles will involve guiding it.

“We have one main constituency who we serve and that is the advertiser — over 90% of our revenue comes from advertisers; there are many buying and selling platforms that do what we do but they have skin in the game, which we don't.”

“DV posted some really good Q2 results — 21% revenue growth, guidance went up and the market noticed; shares went way up and I wish I'd bought more stock before that.”

“Analytics plays a role. They're a commercial company, a consulting business who is looking to garner business. And if they can do so by going after the players that are well established and looking for flaws in the system, that is their prerogative. But what's not a prerogative is actually misstatements and misrepresentations and sampling because that's not going to make the system better.”
