As Chief Technology Officer of Netflix, Elizabeth Stone upholds the company’s high-performance culture by fostering open dialogue and ongoing feedback—eschewing rigid performance reviews in favor of real-time conversations. Central to her leadership is the “Keeper Test,” a method that ensures only top-tier talent shapes Netflix’s innovation. Under her guidance, the company is not just refining its core AI and data capabilities but also expanding its live content strategy, preparing to broadcast NFL games—a move requiring a reimagining of streaming reliability at scale.
A graduate of MIT with a bachelor’s degree in economics and a PhD in the same field from Stanford University, Stone’s career spans finance, health tech, and transportation before she entered the entertainment industry. She previously held leadership roles at Lyft, Nuna, and Merrill Lynch before joining Netflix in 2020 as Vice President of Product Data Science and Engineering. She later led the Data and Insights team, where she shaped the company’s centralized approach to data-driven decision-making. Now, as CTO, she oversees the integration of AI and machine learning to enhance content discovery and optimize streaming experiences.
Stone’s leadership is defined by a balance of technological ambition and strategic discipline. She sees Netflix’s edge not just in its technology but in its ability to harness innovation for storytelling. AI projects under her watch, including an interactive discovery system, aim to redefine how users engage with content. Meanwhile, she keeps the team focused on what truly matters—delivering experiences that set Netflix apart. Her emphasis on radical honesty and trust has not only strengthened the company’s engineering culture but also reinforced its position as a leader in the streaming industry.
