Nick Halla has had a wild arc—from his upbringing on a small dairy farm in Minnesota to becoming employee #1 at Impossible Foods, where he helped turn “meat from plants” into a mainstream, climate-first movement and scaled the company from little more than an idea to a global brand reshaping how we eat. In this episode, Nick discusses ditching his safe career path in big food and energy, betting it all on a radical new way to make meat, navigating the hype and turbulence of the alternative protein boom, and why he now sees “climate” not as an industry but as a design constraint for every business he helps build through GigaClimate, his current venture. It’s a story about serendipity, stubborn optimism, and what it really takes to bend entire systems toward a livable future.

About this episode

Duncan Logan is a Scottish “farm kid” who walked away from a 6,000-acre fruit and veg operation, crashed into the adrenaline of London derivatives trading, and reinvented himself as the founder of RocketSpace, the launchpad that quietly incubated Uber, Spotify, Flexport, and more. In this episode, we trace his swings from battling the National Association of Realtors over a radical real-estate play, to expanding startup hubs into China just as the political winds shifted, to shutting down RocketSpace and starting over with 9Zero, his bid to build the “rails” for climate entrepreneurship and a physical, human-scale Silicon Valley for climate. Along the way, Duncan opens up about regret, risk, compounding, mentorship, political backlash, second careers, and why he believes every company will ultimately become a climate company.

Tim Gray is one of Canada’s most seasoned, quietly formidable forces in conservation and climate action. He’s spent decades in the trenches—from getting arrested at an environmental protest in Northern Ontario to policy backrooms where evidence becomes law—and has built a career translating science into power, confronting entrenched interests, and evolving traditional conservation into a relentless push for deep climate mitigation. This conversation traces the arc of his impact career, from acid-rain fieldwork and old-growth forest fights to shaping modern climate policy and steering Canada through the turbulence of the global energy transition. Now, as executive director of Environmental Defence, Tim is a model for what commitment looks like when it spans a lifetime—and how conservation becomes climate action at scale.
