What if the only way to save nature was to run it like a business?

In this episode, we sit down with Peter Fearnhead, CEO and co-founder of African Parks, the organisation protecting more of Africa’s wild landscapes than any other. Under his leadership, African Parks now manages 24 national parks across 13 countries, covering over 20 million hectares - a model that proves conservation can be financially sustainable, socially empowering, and ecologically transformative.

Peter shares how he’s built one of the most ambitious conservation networks on Earth - from turning near-bankrupt parks into thriving ecosystems, to uniting governments, investors, and local communities behind a single mission. Along the way, we explore why conservation may hold the key to tackling wider economic, humanitarian, and climate crises, and what true leadership looks like in some of the world’s most hostile environments.

This is the story of how business strategy is saving the wild.

The next wave of billion-dollar companies aren’t being built in Silicon Valley – but everywhere else.

For nearly three decades, Linda Rottenberg co-founder and CEO of Endeavor, has been at the centre of that shift. Known as “The Entrepreneur Whisperer,” she’s backed over 350 companies (64 of them unicorns), created “mafias” of founders paying it forward, and built a global movement that’s reshaping economies across 45+ countries.

In this episode, recorded at Trinity College, Cambridge, Linda shares:

• How to scale a business while staying true to your mission.
• The secret underestimated multiplier behind entrepreneurship.
• Why the next generation of entrepreneurs will become more women dominant.
• What makes female founders different.
• The inside view on emerging frontiers and regions to watch.

Linda shows how purpose-driven founders everywhere can scale big - without losing sight of their people or their values.

If you want to understand how high-growth entrepreneurship is being redefined beyond Silicon Valley - and why it matters for the future of innovation - this conversation is a must-listen.

What if compassion wasn’t just a virtue, but a science that could rewire your brain, reduce stress, and even extend your life expectancy?

This conversation is one of our earliest recordings, now released for the first time, with the late Dr. James Doty: Stanford neurosurgeon, New York Times bestselling author, entrepreneur, and founder of Stanford’s Center for Compassion and Altruism Research and Education (CCARE).

Recorded in our early days but never shared until now, this conversation captures Dr. Doty’s extraordinary wisdom on the science and practice of compassion. He explains how compassion rewires the brain, simple self-compassion techniques to silence the inner critic, and why compassionate organisations consistently outperform those built on fear.

Along the way, he reflects on his own journey - from losing $80 million at the height of success to finding true fulfilment in service, and the role the Dalai Lama played in shaping his work at Stanford.

Dr. Doty’s life was devoted to proving that compassion is not soft, but the foundation of human flourishing. We’re honoured to share this conversation from our archives as a tribute to his enduring legacy.

Everyone’s talking about ChatGPT—but what if the real threat from AI is happening elsewhere?

Kristian Rönn is the co-founder of Lucid, a company helping governments track the movement and usage of AI chips globally. He previously founded Normative, the carbon accounting platform that helped shape EU and UK climate disclosure rules—and began his career researching existential risk at Oxford’s Future of Humanity Institute.

He’s also the author of The Darwinian Trap, a bestselling book that explores how misaligned incentives—and short-term thinking—can push systems toward catastrophic outcomes. It’s a framework he now applies to AI, arguing that without global coordination, the very infrastructure powering this technology could spiral out of control.

In this conversation, he explains why AI’s biggest risks aren’t in the models—but in the chips, supply chains, and silent diffusion happening behind the scenes.

We explore:

• Why frontier models are a distraction from the real governance challenge

• The one global policy move governments must make before it’s too late

• What a chicken sandwich teaches us about AI’s hidden complexity

• And what carbon accounting taught Kristian about building systems that actually scale

If you care about who’s really in control of AI—and how we avoid losing the plot—this is essential listening.
