Blue Earth Podcast

In this episode, Guy Hayler sits down with Rembrandt Koppelaar, co-founder and CPO of EcoWise, to explore how the built environment can cut carbon by fixing its biggest bottleneck: messy, manual product data. They unpack EcoWise’s digital product passports and building logbooks, how AI can turn PDFs into usable carbon insights, and why upcoming regulation makes this a “when, not if” shift. Plus: the grant-funded R&D journey, the upcoming £1.5m seed raise, and the roadmap to scale across the UK and Europe.

In this episode of the Blue Earth Podcast, Will Hayler sits down with Chris Boardman to explore what elite sport can teach founders about building real, scalable change. From Olympic cycling to transport policy and system-wide problem solving, Chris shares why progress doesn’t come from sacrifice or virtue alone, it comes from competitive edge. Together they unpack why people change when solutions are materially better, how belief is built through clear pathways, and why framing the prize matters more than repeating the problem. A conversation about performance, behaviour, and designing solutions that actually win, in business, policy and the future economy.

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.

In this episode of the Blue Earth Podcast, Guy Hayler sits down with Mat Ilic, Founder and CEO of Greenworkx, the workforce platform enabling the net zero transition.They explore why the shift to low-carbon homes, transport and energy systems is fundamentally a people challenge; how Greenworkx is tackling the skills and talent bottleneck facing the transition; and what it takes to retrain and upskill the workforce at speed and scale.Mat also shares Greenworkx’s journey so far, the size of the opportunity ahead, and how the company is building a capital-efficient, technology-driven platform to power millions into green jobs.If you want a shorter Spotify blurb, a more investor-led version, or one optimised for Apple Podcasts, I can adapt this quickly.

James shares a bold vision for a “Stellar World”, one of abundance, human flourishing and self-sustaining systems, and explains why today’s biggest challenges can’t be solved by fixing a broken system, but by rethinking it entirely. A hopeful, challenging conversation about technology, civilisation, and the power of seeing the world differently.

In this episode, Guy Hayler sits down with Jack Curtis-Grange, founder of Hydro EV, to explore a radically different approach to EV charging infrastructure. From grid congestion and missed roadside opportunities to off-grid microgrids powered by gas, batteries and hydrogen-ready tech, Jack explains how Hydro EV is unlocking sites other charge point operators can’t reach, and why the business is now raising £500k to scale its first flagship locations.

In this episode of the Blue Earth Podcast, Will Hayler is joined by climate activist Ines and guerrilla gardener and technologist Kalpana Arias to explore what it really means to be heard in a world built on extraction. From getting off the “menu” and onto the table, to reimagining cities, community power and the role of business in driving regeneration, this is a conversation about voice, reciprocity and designing a fairer future, starting exactly where you are.

In this episode of the Blue Earth Podcast, Guy Hayler speaks with Sorina Uleia, Founder and CEO of Recycllux, a 2025 BE100 company and Blue Earth Ventures member. They explore how a personal moment in the sea led to a platform using AI, satellite data and blockchain to detect, trace and orchestrate marine plastic clean-ups. Sorina shares Recycllux’s journey from grants to commercial scale, its £1m seed raise via Blue Earth, and the ambition to build an operating system for ocean regeneration.
