Welcome to Season Nine of Conversations in Cleantech!

This season, we’re going behind the scenes of transition infrastructure - speaking with the investors shaping how, where and why climate capital flows. From decarbonisation and energy security to technology maturity and policy gaps, we’re unpacking what it really takes to fund the systems that underpin a net-zero future.

In this episode, Jenny Gladman and Chloe England are joined by Marieke Beeuwkes Spence, Executive Director at Impact Capital Managers (ICM), a leading network of private capital fund managers that deploys over $80 billion across climate and social impact.

Marieke shares her journey into impact investing, from philanthropy consulting to founding Impact Capital Managers, and offers a grounded yet optimistic look at how private capital can be mobilised for meaningful, long-term change.

Together, they explore what’s driving investor appetite across climate and clean tech, the intersection of AI, energy and biodiversity, and how Impact Capital Managers supports its members through research, collaboration and shared learning. From secondaries and credit to the business case for DEI, Marieke offers rare insight into how market fundamentals are evolving, and where true resilience lies.

This is a conversation about integrity, innovation, and the growing movement of investors proving that strong returns and strong values don’t have to be at odds.
