The "Impact Pioneer" - Sir Ronald Cohen
58:23|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 itFollow us on:YouTube: @HighNetPurposeInstagram: @highnetpurposeTwitter: @HighNetPurposeLinkedIn: high-net-purposeConnect with Sir Ronald Cohen:LinkedIn: Sir Ronald CohenWebsite: sirronaldcohen.orgBooks: IMPACT: Reshaping Capitalism to Drive Real Change (2nd expanded edition, 2025), The Second Bounce of the Ball, ON IMPACT00:00 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 ReflectionsThis podcast is prepared by Islandbridge Capital Limited who are authorised and regulated by the Financial Conduct Authority.All content on High Net Purpose is provided as general information only.

Inside the Technology Rewriting Our Future and Why it Changes Everything
43:50|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 Overview02:31 Sebastian Mallaby on Purpose and His Career05:34 Diplomacy, Complexity and the Economist06:46 How Mallaby Gets Access to Exceptional People09:24 Research as Therapy: The 360 Method10:41 Finding the Central Paradox in Every Subject11:50 First Encounters with Demis Hassabis14:46 Hassabis as Authentic Entrepreneur: The 1993 Vision17:44 Mustafa Suleiman, Geoffrey Hinton and the Co-Founders19:48 Safety Baked In: DeepMind's Founding Tension22:22 Leaked Documents and the Fight with Sundar Pichai25:39 Can Governments Actually Control AI Risk?26:51 The Innovator's Dilemma and the ChatGPT Moment29:35 Hassabis as Leader: Science, Likability and Scale30:32 AlphaGo vs Lee Sedol and What It Revealed33:31 Human Purpose in an AI World35:19 Hassabis on Consciousness and the Meaning of Being Human36:18 AI Investment Framework for Capital Allocators39:27 Health, Writing Discipline and Final Advice
