New York, NY – July 2, 2020 – DoubleVerify (“DV”), a leading software platform for digital media measurement, data and analytics, announced today that Mark Zagorski has been named Chief Executive Officer (“CEO”) of the company, effective July 21st.

Zagorski is a seasoned executive with over two decades of successes in digital marketing and advertising technology – leading companies with a focus on CTV/OTT, data analytics and digital advertising optimization. Zagorski previously served as the CEO of Telaria (NYSE:TLRA), where he was instrumental in building the business into the leading video and CTV monetization platform for premium video publishers. This past year, he helped lead the company’s successful merger with Rubicon Project (NASDAQ:RUBI), creating the world’s largest independent sell-side advertising platform. Prior to joining Telaria in 2017, Zagorski was the CEO of eXelate, where he successfully led the sale of the company to Nielsen and subsequently assumed the role of Executive Vice President – launching and leading Nielsen’s Marketing Cloud Division. During his tenure as CEO of eXelate, Zagorski expanded its global analytics footprint to include billions of consumer data points, and launched its market leading enterprise data platform.

Zagorski will be based out of DoubleVerify’s New York office and will be responsible for managing and growing the company’s worldwide operations, which include over 550 employees in 18 offices globally. As the business accelerates its efforts to become the global standard for measurement across all platforms, Zagorski’s expertise and success in the CTV space will be at the forefront of this drive.

“Mark’s wealth of leadership experience in the digital marketing space makes him an ideal fit to lead DV, and we are thrilled to welcome an executive of his caliber to the team,” said Laura Desmond, DV’s Interim CEO and Lead Director. “He is a strong cultural fit and has a proven track record of building and growing businesses globally. We are confident he will continue to drive DV’s considerable momentum in the years ahead.”

Zagorski said, “DoubleVerify is the industry leader in powering media quality and performance – giving global brands the confidence and clarity needed to make advertising investments on every digital platform. Through their innovative service and solutions, DV has developed deep customer relationships and an outstanding market reputation. There is a huge opportunity to continue to grow the business, and I am energized and excited to leverage my experience in CTV, data and analytics to make this happen. I look forward to working with the talented DV team to further expand its offering of innovative solutions for advertisers and partners.”

“Mark’s industry expertise and experience with both public and private companies will be a tremendous asset to DV as it continues to execute on its growth strategy,” added Davis Noell, Managing Director at Providence Equity and Chairman of the Board at DoubleVerify. “I’d also like to thank Laura Desmond for her leadership as Interim CEO and look forward to continuing to work with her on the Board. She and the entire DV team have done an incredible job pulling together and maintaining strong momentum despite the challenges created by the COVID-19 pandemic.”
