CleanTech Funding in Africa: Who Is Actually Writing the Cheques

For most of the last decade, fintech was the story investors told about African technology. That story has quietly changed. Climate-focused startups now attract more capital than any other sector on the continent, and the shift has happened fast enough that many founders outside the energy space are still catching up to what it means.

The numbers are not subtle. African climate tech startups raised roughly $6.35 billion between 2016 and 2025, according to a report by Briter Bridges, with annual funding climbing from $206 million in 2016 to more than $1.5 billion in 2025. Climate tech accounted for nearly 40 per cent of all disclosed venture capital on the continent last year, overtaking fintech for the first time. The question worth asking now is not whether climate tech is attracting money. It is who is supplying it, and on what terms.

Development Finance Institutions Lead, Not Follow

Unlike the fintech boom, which was driven largely by venture capital chasing consumer growth, cleantech funding in Africa has been shaped from the start by development finance institutions. The International Finance Corporation, the European Investment Bank, and bilateral development banks are not peripheral players here. They are often the first money in.

Husk Power Systems, which builds solar hybrid mini-grids across rural Nigeria, offers a clear example. In May 2025, the IFC and the Government of Canada invested $5 million in Husk’s Nigerian subsidiary, the first disbursement under a $200 million debt facility built specifically to catalyse private-sector energy solutions across West and Central Africa. The European Investment Bank had already provided Husk with $20 million in debt financing to scale its Nigeria operations, at the time the largest corporate debt facility ever extended to a mini-grid company in Sub-Saharan Africa. Dutch development bank FMO and France’s Proparco appear repeatedly across similar deals, backing companies such as Lagos-based Daystar Power before its acquisition by Shell in 2023.

This pattern matters because it shapes what kind of cleantech survives. DFIs are patient by design and comfortable with infrastructure-style returns, which suits solar mini-grids and off-grid power far better than it suits early-stage software. It also means African cleantech founders often spend more time on environmental and social compliance frameworks than their fintech counterparts ever had to.

Debt Has Overtaken Equity

The more striking shift is in the type of capital flowing into the sector. Climate tech in Africa raised a record $1.18 billion in 2025, and debt financing accounted for 54 percent of it, according to data compiled by Lucidity Insights and TechCabal Insights, up from just 30 percent in 2022. Twenty-three debt deals raised $641 million that year, outpacing 81 equity rounds by a factor of two and a half.

Two of the continent’s largest off-grid solar companies illustrate why. Solar energy firm d.light issued a $50 million green bond in June 2025, while rival Sun King raised $286 million through securitised debt around the same period. Both moves were attempts to test whether mainstream capital markets, not just impact investors, would back pay-as-you-go solar at commercial scale. The logic is straightforward: solar hardware generates predictable, metered cash flow from the day it is switched on, which makes it a far easier asset to lend against than a typical software startup with an uncertain path to profitability.

For Nigerian founders, this has practical implications. A cleantech company with hard assets and revenue-generating infrastructure is increasingly better positioned to raise capital than one pitching a purely software-based climate solution, regardless of how compelling the underlying technology is.

Local Capital Is Still Catching Up

International development finance and green bonds explain most of the headline numbers, but domestic African capital remains a smaller part of the picture than the funding totals suggest. Verod Capital, a Lagos-based private equity firm, was among the early institutional backers of Daystar Power, and Nigeria’s United Capital Infrastructure Fund has structured local-currency debt facilities for Husk Power’s expansion. These deals are notable precisely because they remain the exception rather than the rule; most of the largest cleantech cheques in Nigeria still originate outside the country.

That imbalance carries a currency risk that founders and policymakers are only beginning to reckon with. A Nigerian mini-grid operator earning naira from customers while servicing dollar-denominated debt is exposed to exchange-rate volatility in a way that fintech companies, which more often raise and spend in the same currency, are not.

What the Shift Means for Founders

The reallocation of African venture capital toward climate tech is not a temporary correction. Fintech’s share of total funding fell from roughly 60 percent in 2022 to about 25 percent by 2025, according to the same TechCabal Insights data, while climate-focused companies more than tripled their funding over the same stretch. Africa’s energy access gap, which leaves more than 600 million people without reliable electricity, gives this shift a structural logic that is unlikely to reverse quickly.

For founders building in the space, the practical lesson is less about chasing a trending sector and more about matching the capital structure to the business model. Development finance institutions and debt investors are rewarding companies with physical infrastructure and predictable revenue, not necessarily the most novel technology. Nigeria’s cleantech founders who understand that distinction, and who can navigate currency exposure alongside it, are the ones best placed to benefit from capital that shows no sign of slowing down.
