After 18 years at Google - including a decade running Europe, the Middle East and Africa — Matt Brittin has stepped away from one of the most powerful roles in global tech. In this first episode of What We Don’t Know, hosts Hayaatun Sillem and Matt turn the lens inward - unpacking what happens when high-performance leadership stops, and what comes next. Matt opens up about his “midlife gap year,” life after intensity, and learning to be present again following the loss of his father. From a disruptive childhood to rowing for Great Britain — and a very public defeat in the Cambridge Boat Race — he reflects on the moments that shaped how he builds teams and leads under pressure. They also go deep on what really drove Google’s success: hiring at scale, building diverse teams, setting ruthless clarity of priorities, and the simple principle - put the best people on the most important problems, then get out of the way. Plus: navigating public scrutiny on tax, YouTube extremism, and what leadership looks like when you have to say “we got this wrong” — and fix it. This is a conversation about leadership after the job title — and why the most important lessons often come from what we don’t know.

]]> 4395 Trailer: What We Don't Know In a world that feels increasingly chaotic and uncertain, what does leadership really look like - and what do even the most experienced leaders still not know? Hosted by Dr Hayaatun Sillem CBE and Matt Brittin, What We Don’t Know explores the realities of leadership today. Having both recently stepped down from major roles, they reflect on their own experiences while speaking with extraordinary guests from business, politics, technology and beyond. Together, they unpack the moments that shape leaders: crises, difficult decisions, unexpected lessons, and the questions that don’t always have easy answers. From negotiating with world leaders to navigating corporate chaos (and even finding lessons in nature), this podcast explores the human side of leadership - what works, what doesn’t, and what we’re all still figuring out. Follow the show and join the conversation as we explore the biggest question of all: what don’t we know about leadership yet?
