Most of us are in pursuit of purpose, but it can be especially hard to bring purpose into your business. On this show, we invite growing businesses and industry leaders to share their purpose and give us ‘the pitch’.    We want to find out how entrepreneurs and global leaders in our network are allocating capital in a more responsible and purposeful way. But more importantly, we want to know what isn’t in the pitch deck. Joe McCarthy hits his guests with the hard questions in order to find the paradoxes and nuances in their pitches.   High Net Purpose is hosted by Joe McCarthy, founder of Islandbridge, a company focused on helping highly successful people allocate their capital in a meaningful way. Whilst traditional investing is often solely focused on the accruement of more wealth, Joe has been working hard to shift the focus to purpose-led investing and show that’s it’s not black and white, but it is worth it.

  1. The "Impact Pioneer" - Sir Ronald Cohen

    The "Impact Pioneer" - Sir Ronald Cohen

    Welcome to the hotseat where Joe McCarthy sits with Sir Ronald Cohen, co-founder of Apax Partners, Chair of the Global Steering Group for Impact Investment, and author of IMPACT. Sir Ronald is widely regarded as the father of both European venture capital and impact investing. He arrived in London as an 11-year-old refugee from Egypt speaking almost no English, made his way to Oxford and Harvard, and went on to build one of the defining venture and private equity firms of its generation before stepping away to devote himself to what he calls the impact revolution. His argument is simple and radical: governments are stretched, inequality is widening, and relying on taxation and philanthropy alone has failed. The answer is to redirect the trillions already moving through capital markets by measuring impact the way we measure profit. In this conversation he explains why 2026 is a watershed year for that idea, and how AI is changing what is possible. In this conversation, Sir Ronald and Joe discuss the following topics: Why optimising for impact is a route to superior returns, not a trade-offThe hidden risks of impact-blind investing: carbon taxes, consumer flight, and talentWhy carbon tax is the single lever that moves the dial on emissionsHow impact-weighted accounting turns tons of carbon and water into monetary valueThe 1929-to-GAAP parallel and why transparency built modern marketsWhat Harry Markowitz and the measurement of risk teach us about measuring impactWhether public market sustainable investing has any real additionalityMeasuring social impact: pay, representation, and the cost of unemployment to a communityWhere AI meets impact, from education at scale to the first AI-derived drugHow families and family offices should build impact at the portfolio levelGovernments shifting from funding inputs to paying for outcomesHis advice to a younger self: start young, think big, stick with it, and bring impact to it Follow us on: YouTube: @HighNetPurpose Instagram: @highnetpurpose Twitter: @HighNetPurpose LinkedIn: high-net-purpose Connect with Sir Ronald Cohen: LinkedIn: Sir Ronald Cohen Website: sirronaldcohen.org Books: IMPACT: Reshaping Capitalism to Drive Real Change (2nd expanded edition, 2025), The Second Bounce of the Ball, ON IMPACT 00:00 Introduction and Episode Overview 02:33 Sir Ronald's Sense of Purpose 05:18 Refugee Roots and Early Life 06:44 Oxford Union and Learning to Speak Without Notes 09:14 From McKinsey to Founding Apax Partners 10:38 Building European Venture Capital from Scratch 11:48 Deciding to Leave Apax at 60 13:02 The Government Call That Started the Impact Mission 15:36 The Social Impact Bond - From Idea to Peterborough 17:57 Challenges and Surprises in the Impact Journey 20:03 Why Impact Is Not a Trade-Off for Returns 22:54 Carbon Tax as an Investor Risk 24:52 Consumer Preferences - Cycle vs Long-Term Trend 28:12 Impact Weighted Accounting - Origins and How It Works 33:24 From ESG 1.0 to Rigorous Impact Measurement 35:27 Additionality in Public Markets 38:10 Leaders and Laggards - Sector-Level Impact Transparency 41:36 How AI Is Unlocking Impact Data at Scale 44:00 Monetising Social Impact - Diversity Deficits and Employment 46:58 Impact Lenses Across the Whole Portfolio 51:06 Advice for Families and Entrepreneurs Deploying Capital 55:53 Where to Go for Reliable Impact Information 58:23 Governments, Outcomes Funds and the Systemic Shift 01:03:13 Advice to a Younger Self - and the Second Bounce of the Ball 01:04:07 How Sir Ronald Stays Energised 01:05:29 Closing Reflections This podcast is prepared by Islandbridge Capital Limited who are authorised and regulated by the Financial Conduct Authority.

  2. Inside the Technology Rewriting Our Future and Why it Changes Everything

    Inside the Technology Rewriting Our Future and Why it Changes Everything

    Two-time Pulitzer finalist on the scientist who won the Nobel Prize and may not be able to stop what he started. What if the person trying to make artificial intelligence safe is also one of the people racing to build it? In this episode of High Net Purpose, Joe McCarthy sits down with Sebastian Mallaby, bestselling author and two-time Pulitzer Prize finalist, whose latest book explores Demis Hassabis, Google DeepMind and the quest for superintelligence. Over the course of the conversation, Sebastian unpacks the extraordinary story behind DeepMind: why it was built in London, how Demis held onto a mission formed in childhood, and why the race for AI sits at the intersection of science, ambition, safety and power. From AlphaGo’s victory over Lee Sedol to the battle for AI safety oversight inside Google, this is a conversation about what happens when human purpose meets machine intelligence. It asks whether AI will deepen human potential, undermine it, or force us to redefine what purpose means altogether. Along the way, we explore the role of founders, family offices and capital allocators in a world where the technology changes faster than the rules around it. This is the story of the AI paradox, and the man trying to understand the people building the future. 00:00 Introduction and Episode Overview 02:31 Sebastian Mallaby on Purpose and His Career 05:34 Diplomacy, Complexity and the Economist 06:46 How Mallaby Gets Access to Exceptional People 09:24 Research as Therapy: The 360 Method 10:41 Finding the Central Paradox in Every Subject 11:50 First Encounters with Demis Hassabis 14:46 Hassabis as Authentic Entrepreneur: The 1993 Vision 17:44 Mustafa Suleiman, Geoffrey Hinton and the Co-Founders 19:48 Safety Baked In: DeepMind's Founding Tension 22:22 Leaked Documents and the Fight with Sundar Pichai 25:39 Can Governments Actually Control AI Risk? 26:51 The Innovator's Dilemma and the ChatGPT Moment 29:35 Hassabis as Leader: Science, Likability and Scale 30:32 AlphaGo vs Lee Sedol and What It Revealed 33:31 Human Purpose in an AI World 35:19 Hassabis on Consciousness and the Meaning of Being Human 36:18 AI Investment Framework for Capital Allocators 39:27 Health, Writing Discipline and Final Advice Hosted on Acast.

    Lessons From 26 Episodes in 2026

    For the past two years, High Net Purpose has been a series of conversations about other people’s purpose. What we didn’t expect was how much those conversations would change us.   In this episode, we’re taking a break from the usual format to look back at the moments from the first 26 episodes that most influenced our thinking - and ultimately shaped Islandbridge’s journey to becoming the Purpose Driven Multi-Family Office.   This isn’t a highlight reel. It’s a reflection on the ideas that challenged our assumptions, sharpened our values, and changed how we think about allocating financial, human, and intellectual capital.   Along the way, we revisit lessons from guests including: Martha Lane Fox, Diego Piacentini and David Miliband.   This episode is for anyone asking what purpose really looks like in practice - and how listening carefully can shape the way you lead.

    Saving Nature at Scale with African Parks’ Founder, Peter Fearnhead

    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.

  7. How Compassion Rewires Your Brain with Dr. James Doty

    How Compassion Rewires Your Brain with Dr. James Doty

    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.

  8. How We Lose Control of AI - and How to Stop It, with Kristian Rönn

    How We Lose Control of AI - and How to Stop It, with Kristian Rönn

    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.
