00:00 Why Philanthropy Matters in a World of Systemic Challenges

• The conversation opens with the fundamentals: why philanthropy exists, and what makes it uniquely valuable amid today’s interconnected crises.
• Leslie highlights philanthropy’s ability to take risks, test bold ideas and support innovation that neither government nor business can justify alone.
• Peter shares his journey from supporting traditional charitable causes to backing institutions capable of shaping long-term policy, ideas and societal change — a shift driven by the recognition that durable impact requires durable institutions.

11:49 Catalysing Markets, Changing Systems

• The hosts explore what distinguishes strategic, systemic philanthropy from short-term charitable giving.
• Leslie explains how philanthropy can create incentives for business, elevate marginalised voices, and influence market rules and narratives that shape behaviour at scale. She emphasises that philanthropy works best when it catalyses market mechanisms rather than perpetuating dependency.
• Both guests illustrate how supporting new thinking — whether in innovation platforms, city networks, or academic institutions — can spark change that endures beyond any single grant.

19:55 Trends, Risks and the Future of Philanthropic Capital

• Attention turns to the current landscape. Leslie notes the rise of major climate philanthropies, growing collaboration, and more scrutiny of philanthropic influence.
• She also highlights the shift toward venture philanthropy and blended finance approaches.
• Peter emphasises the importance of permanent capital — endowments or large, long-term commitments — that allow institutions to plan confidently, attract talent, and deliver meaningful, multi-generational impact. He contrasts this with piecemeal, project-by-project philanthropy, which often limits effectiveness.

29:18 Leadership for the Long Term: What Works, What’s Next

• The final chapter examines the leadership mindsets required to drive systemic change. Both guests argue that long-termism is a leadership discipline, not a luxury, and that short political and commercial cycles remain one of the biggest barriers to change.
• Peter underscores that impact depends on backing the right people in the right institutions — and giving them the freedom to take risks and think for the long term.
• Leslie highlights the need for leaders who think multigenerationally, prioritise contribution over attribution, and stay focused on shifting the underlying conditions, incentives and norms that shape our economies.
