Tom Kershaw is one of the most influential engineering leaders in programmatic advertising, serving as Chief Technology Officer at Magnite — the largest independent sell-side platform in the world. His work sits at the intersection of real-time bidding infrastructure, connected TV, and video advertising technology, where he has helped shape how premium publishers and broadcasters monetize their inventory at massive scale. Kershaw has been a consistent voice in advancing open standards and technical best practices across the supply side of the programmatic ecosystem. Kershaw's career trajectory runs through some of the most consequential companies in video and CTV ad tech. As CTO of Telaria (formerly Tremor Video), he led the engineering buildout of a purpose-built CTV and video SSP, positioning the company as a technical leader in server-side ad insertion (SSAI) and programmatic video before its landmark merger with Rubicon Project in 2020 to form Magnite. That merger, which he helped navigate from a technology integration standpoint, created a combined platform processing billions of daily ad transactions across display, video, mobile, and CTV. Beyond his operator role, Kershaw has been active in industry standards bodies, contributing to initiatives around transparency, identity, and interoperability in programmatic advertising. His technical depth in RTB systems, auction mechanics, and streaming video infrastructure makes him a respected figure among both engineers and business leaders in the AdTech space. He is frequently cited as a key architect of the modern CTV monetization stack.
