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, our host Jenny Gladman is joined by Laurie Menoud, Founding Partner, and Helen Lin, Partner at At One Ventures - a firm reshaping climate investing through the lens of deep tech, scientific rigour and radically better unit economics.

With backgrounds spanning biotech, physics, finance and microfinance, Laurie and Helen are part of a founding team built on diverse experience and shared conviction. Together, they’re investing in breakthrough technologies that aren’t just greener - they’re fundamentally better, more scalable and economically inevitable.

The conversation explores how At One Ventures uses a “physics fundamentals” framework to de-risk investments, why climate tech must work with, not against, economic logic, and how to navigate the time-cost tradeoffs of scaling hard tech. From bridge rounds to manufacturing missteps, this is a rare look into what actually makes or breaks impact at scale.

It’s also a conversation about trust, humility and the human side of venture. Laurie and Helen share why founder relationships are core to their strategy, and how radical candour, curiosity and alignment can turn investors into true long-term partners.
