Episode 9 features Sarah Greasley, former Group CTO at Direct Line and AWS EMEA Director, who shares insights from her nearly four decades in technology. She discusses what defines a modern CTO — from trust, curiosity, and vision to balancing technical depth with strategic and commercial awareness. Sarah explores how storytelling and relationship-building are key to influencing at the C-suite level, and reflects on the growing diversity of CTO roles, from startups to enterprises. She also opens up about her transition into a portfolio career, the realities of becoming a Non-Executive Director, and the importance of mentoring and growing future tech leaders.
