The Samuele Tini Show - where business, innovation, and sustainability converge

Stop Funding Apps. Fund Warehouses. | Claire van Enk

Up to 50% of Kenya's fruits and vegetables never reach a plate. Not because farmers can't grow. Because nobody can reliably move, sort, price and pay.
Claire van Enk is the founder and CEO of Farm to Feed, a Nairobi-based agritech platform that today connects 6,000 smallholder farmers with hotels, restaurants, schools and food processors across Kenya through bespoke logistics, traceability and a 200-SKU catalogue that includes "grade rescue" produce too imperfect for conventional buyers. The business started as a COVID-era GoFundMe in 2020. Five years and one commercial pivot later, it is one of the most ambitious operational businesses in East African food.
In this episode of The Samuele Tini Show, Claire makes a case that cuts against most of the African startup conversation: the continent does not need more cloud-based platforms. It needs warehouses, trucks, cold rooms and the unglamorous logistics that physically move food from a farm to a kitchen. Investors prefer asset-light businesses. The real bottleneck is physical.
We talk about the fragmented food system, the multiplier effect on rural employment, the limits of traceability in a country with weak pesticide regulation, and the "Africa discount" that keeps Kenyan products underpriced on global markets. Claire also shares the hardest founder lesson of her journey: realising she had to stop being an entrepreneur and start being a CEO, and that the two are not the same job.
A direct, honest conversation about food systems, climate-resilient supply chains, and what it really takes to build operational businesses in Africa.

GDP Became Our God: The Religion of Economic Growth | Tim Jackson

What if the obsession driving the global economy is not a strategy, but a religion?
In this episode, Professor Tim Jackson (University of Surrey, author of Prosperity Without Growth, Post Growth, and The Care Economy) argues that GDP has filled "the God-shaped hole" left in the 20th century, becoming a creed we recite without questioning. Sam and Tim explore where this obsession came from, why technology alone cannot decouple growth from environmental damage, and how a different organising principle, care, could replace growth as the engine of the economy.
Tim makes the case that prosperity was never about income. It was about health, balance, and the ability to thrive within limits. Drawing on Wangari Maathai, Ubuntu, and the autonomic nervous system as a metaphor for governance, he reframes the role of rich countries: not to help the Global South, but to take their foot off the accelerator.
A conversation about economics, philosophy, indigenous wisdom, and the kind of business worth building.
 

There Is No Funding Gap in Africa. Here's What's Actually Missing

"There is no funding gap in Africa."
That is the provocation from Burak Buyuksaraç, CEO of Afri Capital and a 16-year business veteran in Tanzania. He arrived in Dar es Salaam in 2010 as a mining executive, stayed to build a diversified portfolio across tourism, security, insurance, consultancy and trading, and now runs one of East Africa's newer investment firms.
In this episode we unpack why the real bottleneck in African SME finance is not capital but pipeline. Why smaller tickets are harder to raise than larger ones. Why Tanzanian banks demand 125% collateral for a loan. And why Burak sees Africa and Latin America as the only two regions left on the planet with genuine room to grow.
Burak shares two recent Afri Capital deals: a $15M refinancing for an Arusha agro-processor and a $3.5M facility for a Tanzanian bank servicing the education ecosystem.
Essential listening for founders, impact investors, DFI teams and anyone working on SME finance in emerging markets.

Space-Based Solar: The $10 Megawatt Hour That Can Save Us | Martin Soltau

Oil above 100 USD. The Strait of Hormuz under pressure.The world scambling for energy. Again. and Again...
Every energy crisis sends us looking for the same answers: another pipeline, another terminal, another sanctions package. But what if the real way out is not on Earth at all?
Martin Soltau, Co-CEO of Space Solar, returns to the show with a roadmap that has hardened into something impossible to ignore. His UK startup, nine people and £10 million in funding, is building Cassiopeia: a modular solar power satellite designed to harvest energy in geosynchronous orbit and beam it down to receivers on Earth, 24/7, all weather, gigawatt scale. Independent analysts price it at around $10 per megawatt hour, roughly ten times cheaper than today's wholesale energy. A solar panel in orbit produces 13 times more energy than the same panel on the ground.
In this conversation we get into the part most people miss. This is not a physics problem, it is engineering the economics, and the milestones are real. First in-orbit demonstration in two years. Minimum viable product by 2030. First commercial 600 MW satellite in geosynchronous orbit by 2033. Martin makes a sharp case for why wind and solar alone cannot scale fast enough, why the UK is now paying the highest energy prices in the developed world despite one of the world's most ambitious clean energy programmes, why orbital data centres are the wrong answer to AI's energy hunger, and why a technology that uses 1000 times less critical minerals than ground-based renewables could finally break the link between energy and geopolitics.
If you care about energy security, decarbonisation, or where the next decade of clean power is actually coming from, this is the conversation worth your time.

Fish Don't Vote: Why the Ocean Crisis Keeps Getting Ignored | Antoinette Vermilye

73,000 sharks are killed every day. 16,000 chemicals are added to plastics, and only 1% are regulated globally. The ocean is in crisis, but almost nobody sees it.
Antoinette Vermilye (Co-Founder, Gallifrey Foundation & SHE Changes Climate) has spent over a decade connecting the dots between ocean destruction, human health, climate finance, and gender in global negotiations. In this episode, she walks us through how her team convinced 60 airlines to stop carrying shark fins, why the plastics treaty negotiations keep stalling, what "carbon cowboys" are doing to blue carbon projects, and why biodiversity of perspectives matters as much as biodiversity in nature.
What you'll learn: How systems change actually works in ocean conservation. Why regulation, accountability, and penalties are the missing link. How blue carbon credits can work fairly. And what you can do right now with your voice, your vote, and your pocket.
A conversation that will change how you see the ocean and everything connected to it.

AI and Ubuntu: Can Ancient African Wisdom Fix Modern Technology? with Wakanyi Macharia-Hoffman

What if the ethical framework AI needs was coined thousands of years ago in Africa?
Wakanyi Macharia-Hoffman is co-director of the Inclusive AI Lab at Utrecht University and founder of the African Folktales Project. She grew up near Ngong Forest in Kenya, where her primary school was literally inside the forest. Today she's on a mission to recover African indigenous knowledge and bring it into the spaces where it matters most: classrooms and technology labs.
In this episode we explore:
Ubuntu as relational intelligence: from self, to community, to planet
The ulimi sana algorithm, designed at the University of Johannesburg, that optimizes AI for cooperation instead of competition
How 17 African folktales mapped to the 17 SDGs are reshaping education for 21,000+ teachers worldwide
Why AI is a mirror of humanity, and why the real question isn't what AI will become, but who we are becoming
Whether you work in tech, education, sustainability or development, this conversation will change how you think about innovation, indigenous knowledge, and what it truly means to be human.

Own the Road: Lessons for African Entrepreneurs

When Tonderai Njowera's father came home and asked, "Did you know you can own a highway?" it changed everything. That one question sent a young boy in Zimbabwe on a journey from civil engineering to investment management to venture building in Cape Town.
In this episode, Tonderai breaks down why Africa's biggest challenge isn't lack of capital or resources but a leadership gap. He argues that protectionism is the wrong response to global competition: African entrepreneurs need to think globally, not retreat locally. Using a powerful Formula One analogy, he explains how underdogs win by reading the conditions and capitalizing on disruption.
Key insights from the conversation:
Infrastructure is more than roads and bridges. It includes cultural and educational foundations that shape innovation capacity.
The current global economic reset is an equalizer. Smart entrepreneurs can use it as a launchpad.
Long-term thinking must coexist with short-term execution. The challenge is mixing the dose right.
Family offices, DFIs, venture capital and grants each play a distinct role in the long-term investment picture.
Tonderai Njowera is an entrepreneur, systems architect, and investor based in Cape Town, with roots in Zimbabwe's engineering and infrastructure sectors.
Listen now and rethink what "competitive advantage" means for African founders.
 

Stop Disrupting, Start Building with Costas Papaikonomou

What if the most profitable climate investments aren't sexy at all? Costas Papayconomou, co-founder of Una Terra, spent a career in innovation consulting (including building and selling an agency to Accenture) before turning to circular economy investing. His thesis is simple and counterintuitive: don't disrupt old industries, clean them up. In this episode, Costas walks us through investments that sound boring but are brilliant: a cellulose-based white colorant replacing toxic titanium dioxide (with IKEA as lead investor), smarter food packaging that cuts energy use while making meals taste better, and paper pulp innovations. He shares why founding teams should be obsessed with customers, not investors. Why they literally added "does this violate the laws of physics?" to their deal screening. And why the talent war, not regulation, will ultimately force every industry to go green. His closing advice: look for the smallest problem that affects the most people. 

Africa Doesn't Need the West. The West Needs Africa

What if the most powerful innovations don't come from billion-dollar labs, but from people who have almost nothing?
Navi Radjou left Silicon Valley after 13 years because he realized most innovation there serves the top 1%. Now based in Bangalore, he's spent two decades proving that resource scarcity breeds the most radical creativity. In this episode, Navi breaks down why Africa is set to become the world's innovation lab, not its charity case. He introduces the "frugal economy" model built on three pillars: cooperation over competition, decentralized production over mega-factories, and regeneration over extraction. From Hello Tractor (the Uber for small farmers) to Levi's sharing proprietary tech with rivals, Navi delivers a blueprint for a post-capitalist economy rooted in Ubuntu philosophy. His parting shot: the world's biggest crisis is a crisis of imagination, and Africa holds the answer. Listen now on samueletini.com

Women Don’t Own Their Time: The Hidden Constraint on Entrepreneurship

In this episode, I’m joined by Alisa Sydow (Professor of Entrepreneurship at ESCP Business School) to unpack what women founders are really navigating in Africa’s entrepreneurship ecosystem beyond the usual “barriers list.”
We discuss:
Why purpose is powerful—but can also limit growth if it makes founders neglect commercial fundamentals.
The overlooked role of founder identity (and why some women subconsciously place business last).
The gap between policy and lived reality in finance access (including stories shared by founders in 2025).
A practical, grounded view of product uniqueness, market fit, and why the local market is often underestimated.
Why “trendy” international calls for proposals can distort markets and push founders toward the wrong models.
 
If you mentor founders, invest, design entrepreneurship programs—or you are building yourself this is an episode to bookmark.
