  • Old Salt Co-op: How a Montana Town Is Reclaiming Its Food Future
    Feb 19 2026

    “Land is kin.”

    It’s the mantra at the heart of what guides Cole Mannix and Old Salt Co-op.

    Old Salt is a meat company built by ranchers to take the power back from Big Beef. They do everything from pasture to plate, running multiple restaurants and an annual festival that draws thousands to Montana around food, art, and community.

    This is also a deeply personal story born out of a promise to save his own ranch. Cole serves land, legacy, and community - and represents what it means to take responsibility for a place and the people who depend on it.

  • Lufa Farms: How to Grow Food on Top of a City
    Feb 5 2026

    It’s an idea so simple it could come from a five-year-old.

    At least that’s how Lufa Farms founder, Mohamed Hage, refers to their idea of turning idle rooftops into working greenhouses. But the real story - and this conversation - is about what it takes to build it, and what becomes possible once you do.

    In Montreal, Lufa has become a household name for its rooftop farms, local food delivery, and hunger relief work - and that’s just the beginning.

    Alongside Mo, we’re joined by Dave Furneaux, a seasoned investor and builder, to talk about their friendship, what makes the “soul” of a business, and why the risks of doing something transformative are worth it.

  • Coral Vita: How to Rescue a Coral Reef
    Jan 22 2026

    Coral reefs are disappearing fast - and they matter more to our daily lives than most of us realize. Sam Teicher, co-founder of Coral Vita, joins the pod to explain their fascinating approach to reef restoration, which he calls “taking coral to the gym.” We talk Category 5 hurricanes, why the Bahamas is leading this work, and why coral reefs matter whether you live by the ocean or nowhere near one. We’ve all heard what’s going wrong in the climate change fight - this is a conversation about what’s still possible.
