Prebid.org named Garrett McGrath as its first president on September 10, and the timing matters more than the title change. McGrath is the former Senior Vice President of Product Management at Magnite and had chaired Prebid’s board for years before stepping into the newly created operating role, where he will run day to day strategy, member growth and the technical roadmap for the header bidding standard that most publishers use to run auctions across multiple ad exchanges at once.
Why it matters: Prebid exists because publishers did not want to depend on a single company’s ad server to referee which exchange wins a given impression, and it becomes more relevant, not less, the moment a court forces a change in how Google’s own stack has to behave. “The open internet is undergoing a massive structural evolution. Prebid is the connective tissue holding the open web together,” McGrath said. Joel Meyer, Prebid.org’s board chairman, said the organization needed exactly this kind of operator at the helm now: “Few people understand both the technology and the community as well as Garrett does, making him exceptionally well-positioned to guide Prebid into its next era.”
The original insight: creating a dedicated president role, rather than continuing to run Prebid through a volunteer board chair, signals the organization expects a heavier operating load ahead, from AI-driven programmatic buying standards to identity tools like its SharedID project. Katie Morgart, Prebid.org’s VP of marketing and strategic partnerships, tied the appointment directly to that pressure: “The industry is shifting and independent publishers need transparent, open source alternatives more than ever.” That framing lands the same week a federal court left Google’s ad stack intact under new, still sealed conduct rules rather than breaking it up, which is precisely the scenario open source infrastructure like Prebid was built to hedge against, and it follows a year in which the group has already pushed a standard way for AI agents to enter ad tech and watched curated supply deals like Adnami’s move into DV360 route more inventory straight into walled garden DSPs.
