Foreva Farmers: Profitable in 2 Years, Zero External Funding | Charlie & Ollie Allen

Most drinks brands take ten years to reach profitability. Foreva Farmers is on track to do it in two — and without raising a penny of external capital. In this episode of Profit Meets Purpose, host Harvey Knight talks to the Layton brothers, founders of Foreva Farmers and winners of the Sustainable Times RISE Awards 2025 Consumer Product Category. The Laytons have built something rare: a vertically integrated consumer brand where they own the water, the energy, the food-grade CO2 carbonating the drinks, and the canning line itself. The result is a unit cost that matches established producers running fifty times their volume — and a business that's reaching profitability bootstrapped. In this conversation: The vertical-integration model that lets a Herefordshire farm match incumbent unit costs at fifty times the scale. How an existing renewable energy business is funding the launch of a consumer drinks brand from cash flow. Why their anaerobic digester is technically carbon-negative — and why no third party currently certifies that claim. The hardest founder lesson: pricing too low to match competitors instead of pricing to reflect the product. Why "story comes second" is the standard drinks-brand mistake — and how the Laytons built theirs differently. — Connect with Foreva Farmers: Website: forevafarmers.com/pages/our-farm Instagram: @forevafarmers LinkedIn: linkedin.com/company/foreva-farmers Charlie Layton: linkedin.com/in/charlesoscarlayton — About the show: Profit Meets Purpose is the official podcast of Sustainable Times — the UK platform connecting sustainable founders with institutional and HNW investors.

The £200 Billion Problem That Algae Might Solve | HutanBio Founders

Six years of continuous algae cultivation. Zero crop failures. A world first. In this episode of the Sustainable Times Podcast, we sit down with HutanBio CEO Manshu Agarwal and Founder & Chief Scientific Officer Dr John Archer — the Cambridge-based biotech quietly building one of the most credible answers to the hard-to-abate fuel problem. Where ExxonMobil walked away from algae biofuel and competitors like Viridos spent years on genetically-modified strains, HutanBio took a fundamentally different path. Their proprietary marine microalgae strain, Sphaerica — discovered through a multi-year bioprospecting programme in extreme tropical marine habitats — delivers up to 10x the yield of previous algae and oil crops. No genetic modification. No fresh water. No competition with arable land. Grown on seawater, in desert environments, using only CO₂ and sunlight. The result: HBx Bio Oil — a net-negative carbon biofuel designed for the sectors fossil fuels still own. Maritime. Aviation. Heavy land transport. What we cover: — The two-decade scientific journey from Cambridge and KAUST to commercial deployment — Why the algae biofuel market has failed before, and what HutanBio is doing differently — The Sphaerica discovery and what makes it commercially defensible — Building a high-yield, modular production platform engineered for desert deployment — The £2.25m Clean Growth Fund investment and what scaling looks like next — The IMO 2030 emissions mandate and why maritime is the beachhead market — What investors should understand about the hard-to-abate fuel opportunity in 2026 — GUESTS Manshu Agarwal — CEO, HutanBio linkedin.com/in/manshuagarwal [linkedin.com/in/manshuagarwal] Dr John Archer — Founder & Chief Scientific Officer, HutanBio linkedin.com/in/john-archer-b551569 [linkedin.com/in/john-archer-b551569] Harvey Knight — CEO & Founder, Sustainable Group linkedin.com/in/harvey-knight-38aa91a9 [linkedin.com/in/harvey-knight-38aa91a9] — ABOUT HUTANBIO Founded in 2019 by Dr John Archer (Cambridge), Dr Noor Azlin Mokhtar, and Suhaiza Jamhor, HutanBio is a UK-based climate biotech developing scalable, net-negative carbon biofuels from proprietary marine microalgae.

Host: Stuart Hall, Managing Director, Sustainable Media Group Guest: Robin Grenfell Cowan, High-Net-Worth Investor Episode Overview In the first episode of the Sustainable Times Investor Series, Stuart sits down with HNW investor Robin Grenfell Cowan to explore how early-stage investment decisions are really made in private markets.

It’s a grounded look at how investors actually think, something both founders and early-stage investors will find useful as the market resets for 2026.

Ep.35 Claire Tange, Joanna Invests

“When you change who invests, you change what gets built.” This week on Profit Meets Purpose Claire Tange, Co-Founder of Joanna Invests, discusses the community of female investors and founders she has built since 2022. Claire saw the problem of gender inequality first-hand while working in both investment banking and startups. “We need to be smarter with our money,” she says. “Once we have it, we need to invest.” Even for willing investors, Claire says, deal flow is hard to access without an established network and harder still when focusing on female founders. Since the first deal in 2022, into tech platform ‘We Are Eves', described as TripAdvisor for beauty products, Joanna Invests has backed ten female-founded companies across sustainability, fintech, health, and sport. Joanna Invests has placed great emphasis on the value of community. Before investment, founders host webinars with potential investors. Afterwards, Joanna Invests arranges small “investor dinners” at the founders’ offices, where women meet the people behind the products they’re backing. “Those evenings are incredibly energising,” she says. “Women ask different questions; they're more interested in understanding how the business really works, not just what the numbers say”. Ultimately, Claire wants Joanna Invests to complete the loop by funding female founders who later become investors themselves. “That’s the goal,” she says. “You invest in them, they build something successful, they exit and then they come back and invest in the next generation.” Listen to the episode for the full conversation with Claire and learn how Joanna Invests is empowering a generation of female investors.
