What does it really take to build a digital bank for Africa’s green economy, and why might carbon credits become one of the continent’s most valuable exports? In this episode of The Grinders Table, Uwem sits down with Mélanie Keita, CEO and co‑founder of Melanin Kapital, a carbon neobank lending to agricultural, cleantech and carbon projects across 12 African markets.

Mélanie shares her journey from Paris, Frankfurt and impact investing into the grind of launching a fintech while broke, why being “rich or deeply networked” matters when your product is money, and the hard lessons she’s learned about delegation, team building and surviving five-plus years of pivots. She unpacks how Melanin Kapital evolved from a diaspora crowd‑lending platform into a lender of record and now a carbon neobank using carbon credits to bring down the cost of capital for SMEs.

You’ll hear a candid take on “fake it till you make it” (and why it’s a fast track to orange jumpsuits), why founders should spend 30–40% of their time on relationships instead of spreadsheets, and how banks quietly buy SME loan books as a form of exit and liquidity. We also dive into Article 6, why Ghana is ahead on carbon regulation, how Africa is leaving billions on the table, and what policymakers and founders must do to put the continent at the center of climate finance rather than at the margins.

Florent "Flo" Nduwayezu is a Nairobi-based investor at FP Capital, and one of the most consistently honest voices in African tech. He's Burundian, he's been in Nairobi for 13 years, and he has very little patience for the narratives that keep African ecosystems stuck.

In this episode, Flo sits down with Uwem to challenge some of the most comfortable assumptions in African VC, starting with SaaS. His argument: African SMEs never really adopted it, and with AI agents taking over the interface layer, SaaS is about to become invisible infrastructure at best. What replaces it? Integrated solutions that meet people where they already are - on WhatsApp, on audio, offline.

But the more uncomfortable conversation is about talent. Flo breaks down the math: if Kenya deployed close to $900M in venture capital, you need significant exits to justify that. You need multiple large companies. Each of those companies needs serious engineering depth. And his question, bluntly put, is whether that talent pool actually exists at the quality and concentration required.

They also go deep on impact investing's unintended consequences, why African VCs need to get more involved in policy, why Rwanda is doing something the continent's "Big Four" should be paying close attention to, and why Flo thinks he might eventually have to go into politics.

Dr. Dotun Olowoporoku didn't take the typical route to venture capital. He started as a PhD researcher on air quality and climate change, stumbled into entrepreneurship with an online food delivery startup, became CCO at Moniepoint during its most critical growth years, and then became Managing Partner at Ventures Platform, one of Africa's most founder-supportive seed funds.

In this episode, we go deep on the questions the ecosystem rarely asks out loud: What does portfolio support actually look like when a company is dying? When does investor support become dependency? Which African companies does VC money quietly destroy? And is the AI wave signal or hype?

Dotun also shares how he spotted Tosin Eniolorunda's thesis before Moniepoint was Moniepoint, why he evaluates every investment as a research hypothesis, and what the Capitec Bank story from South Africa taught him about the future of African fintech.

If you're a founder, an investor, or anyone building on this continent, this one will make you think differently.
