Rebuilding Performance Apparel, Without the Waste | Ed Bartlett, Founder of Kostüme

Season 2, Ep. 50

In this episode of the Blue Earth Podcast, Guy Hayler sits down with Ed Bartlett, founder of Kostüme and Blue Earth Ventures member, to explore how a 25-year founder journey, from raising $50m in the gaming industry to curating contemporary art, led to rebuilding performance apparel from the ground up.


Ed shares how Kostüme flips the traditional retail model on its head: limited batch drops, pre-order production, no discounting, radically reduced waste, and award-winning technical cycling kit designed for how people actually ride.


They discuss breaking broken systems, building brand trust without paid ads, scaling sustainably, and why the ambition goes far beyond cycling.


If you’re interested in consumer brands, circular models, performance wear, or founders rewriting the rules, this one’s for you.

  • 46. How Seaweed Could Decarbonise Cattle

    25:53||Season 2, Ep. 46
    In this episode of the Blue Earth Podcast, Guy Hayler sits down with Mayleah House and Chris De Cuyper from Fremantle Seaweed to explore one of the most promising nature-based climate solutions emerging from Western Australia. Fremantle Seaweed grows asparagopsis offshore and turns it into a cattle feed supplement proven to reduce methane emissions by up to 90%, while improving feed efficiency for farmers. It’s a rare example of science, nature and commercial viability aligning to tackle a major source of global emissions. They discuss the science behind the breakthrough, why growing seaweed in the ocean matters, how supermarkets and food supply chains are driving demand through Scope 3 targets, and what it takes to build an infrastructure-heavy climate startup from the water up.Recorded shortly before Mayleah travelled from Australia to pitch at the Blue Earth Investment Forum, this conversation connects ocean innovation with the capital and partnerships needed to scale it worldwide.
