Cassie Kozyrkov

Cassie Kozyrkov is a globally recognised expert in artificial intelligence and the founding figure of Decision Intelligence. During her ten-year tenure at Google, she served as the company’s first Chief Decision Scientist, where she was instrumental in transitioning the organisation into an AI-first entity. Her work involved guiding over 500 high-impact projects and personally educating more than 20,000 members of staff in data-driven strategy and machine learning. Originally from South Africa, she began her university studies at age 15 and holds various degrees spanning mathematical statistics, economics, psychology, and neuroscience. Today, she advises global leaders at organisations such as NASA, Gucci, Meta, and GSK on the implementation of effective, responsible tech strategies. Her work focuses on the intersection of data science and social science, helping executives understand the chain of cause and effect between organisational actions and resulting outcomes. By bridging the gap between technical capability and human behaviour, she enables businesses to navigate complex systems and move beyond simple data analysis to robust decision modelling. She also shares her expertise as a lecturer at Harvard Business School and has featured prominently in publications including Wired and Harvard Business Review. Cassie is frequently booked for her unique ability to demystify generative AI and the future of technology for non-expert audiences. She provides leaders with the clarity required to build practical strategies that prioritise human potential and business value in an increasingly automated world.
