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.

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.

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.

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

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.

Syntropy isn’t about the tropics—it’s about the physics of life. In this episode, Samuele sits down with Sven Verwiel, CEO & Co‑Founder of Forest Foods (Kenya), to unpack syntropic agroforestry: a regenerative farming approach designed to compound productivity over time through stratification (vertical layers) and succession (time).

We go from field reality to unit economics: what it takes to regenerate degraded soils, why syntropic systems can reach ~200–230% land‑use efficiency, and how Forest Foods is proving a commercial model with outdoor production, zero chemicals, and strong market demand for premium quality.

We also discuss livestock integration (pasture‑raised chickens), the hardest founder challenges (land access, capital, logistics, cold chain), and why regenerative agriculture must become a career path that attracts the next generation.

Key topics: syntropy vs entropy, soil regeneration, agroforestry design, profitability, go‑to‑market, scaling regenerative food systems in Africa

In this episode, Samuele speaks with Apollo Gabazira—Country Director at CARE International (Uganda) and an award‑winning regenerative farmer—about what it takes to make farming profitable, scalable, and youth‑attractive in East Africa.

Apollo shares the Asaba Farm System and its “quad model”:

1. dairy as a foundation

2. agronomy and circularity (turning waste into value)

3. skilling youth through hands‑on learning

4. community extension through local one‑stop hubs (“Farmers Point Outlets”)

We also unpack Apollo’s most actionable insight: the 80/20 rule in dairy—focus on nutrition and reproduction to shift the majority of outcomes, from milk yield to economics.

Finally, we zoom out to the bigger levers: what must change in policy, access to capital, and public‑private collaboration so regenerative and climate‑smart agriculture can become the norm—not the exception.

Key topics: profitable regenerative farming, extension models, youth skilling, policy, capital, SME partnerships.

When you clear a forest to plant maize and make charcoal, you’ve already put a price on nature—the future cash flows from the maize and the wood. The problem is that price is far too low.

In this episode of The Samuele Tini Show, I speak with Josep Oriol, Managing Partner at Okavango Capital Partners and a leading nature‑finance expert working across Sub‑Saharan Africa.

A Catalan who fell in love with African wildlife as a child, Josep trained as a lawyer, moved into venture capital and banking, then finally to Southern Africa to build a different kind of private equity firm—one that backs nature‑positive businesses whose performance depends on how they treat forests, soil and water. Today, Okavango‑backed companies help protect around 8–9 million hectares of land (about twice the size of Switzerland) and create income streams for hundreds of thousands of rural people.

We dive into:

• The mispricing of nature: every land‑use decision—from forest to maize field—is already a price signal, and why that’s dangerous if we ignore the true value of ecosystems.
• Forest carbon in practice: the story of BioCarbon Partners, REDD+ projects, and rural families living on ~$20/month in cash who now earn income by keeping forests standing.
• Carbon market backlash: Josep’s response to critics of carbon credits, and why, compared to agriculture, mining or logging, high‑integrity projects are often far more transparent and generous to local communities.
• Three big opportunity themes:
  • smarter agriculture and agroforestry to boost yields and cut waste,
  • tech for soil, post‑harvest, insurance and finance,
  • monetising ecosystem services via tourism, carbon, biodiversity and water credits—and why fuelwood is still the elephant in the room.
• Why classic 5‑year 10x PE funds don’t fit Africa: and how Okavango uses longer horizons and flexible instruments (loans with equity options, convertibles, prefs) instead of only straight equity.

We close with Josep’s advice for entrepreneurs in nature‑based sectors—live with existential threat, love cash flow and margins, and assume everything will take twice the time and three times the money—and his vision of Africa’s future looking more like South Korea or Malaysia than Europe, if we get the nature piece right.

If you care about where climate capital should actually go, this is a sharp, grounded conversation from inside the deal flow.
