Bio
Mark Zagorski is the CEO of DoubleVerify. Zagorski views programmatic advertising as the biggest technological shift of the past two decades, noting that it moved the buying and selling of digital media from humans to data-driven machines bidding on impressions, and he sees AI as setting the stage for the next major transformation. He has emphasized connecting measurement to business outcomes — ultimately whether an ad drove a sale — moving the discipline away from static metrics toward something active and actionable. DoubleVerify is preparing to be acquired by Nielsen Holdings, which announced it will buy the company for $13.60 per share in cash, valuing it at approximately $2.15 billion.
