In 2025, ClimateTech officially became Africa’s leading venture capital sector. Companies in the space raised over $1.5 billion throughout the year, accounting for nearly 40% of all disclosed VC funding across the continent. Yet behind this remarkable milestone lies a highly concentrated market: a handful of companies, sectors, and countries continue to absorb the vast majority of capital. This is the central finding of The State of ClimateTech in Africa 2.0: Moving Beyond the Headline Numbers, a report published by Briter in partnership with Catalyst Fund, FSD Africa, and BFA Global, with support from Africa: The Big Deal.
Record Growth, But Deep Concentration Persists
The scale-up over the past decade is unmistakable. Annual funding surged from $206 million across 28 companies in 2016 to over $1.5 billion for 223 companies in 2025. Between 2016 and 2025, approximately 779 ClimateTech firms mobilized roughly $6.35 billion in total. This growth has propelled ClimateTech past fintech as the largest share of disclosed annual investments on the continent.
However, headline figures only tell part of the story. The top 20 best-funded companies alone captured 60% of all capital raised since 2016. In fact, the top 10 firms secured as much funding as the rest of the sector combined. In other words, rising investment totals do not yet signal broad-based ecosystem growth. Concentration is also heavily skewed by sector. Energy solutions accounted for roughly 65% of ClimateTech funding between 2019 and 2025, far outpacing mobility and transport, which captured around 11%. Companies like Sun King, d.light, and CrossBoundary Energy have been among the primary beneficiaries of this trend.
Sector & Geographic Imbalances Reflect Market Maturity
This imbalance largely reflects differing levels of market maturity. Energy solutions already boast proven business models and clearly defined infrastructure needs, making them attractive for larger funding rounds. Other sectors—such as agriculture, water management, circular economy, and climate resilience—still struggle to translate their impact potential into predictable revenue streams that satisfy traditional investors.
A similar pattern emerges geographically. Kenya alone accounts for just over half of all African ClimateTech funding. Together with Nigeria and South Africa, these three nations represent approximately 76% of total investments. Capital flows remain heavily anchored to a few mature ecosystems capable of attracting the largest checks.
The Early-Stage Funding Gap & Shifting Capital Structures
Yet the funding gap isn’t just a growth-stage challenge—it starts much earlier. Between 2019 and 2025, equity deals under $500,000 made up less than 0.5% of total sector funding. For early-stage startups building prototypes, testing markets, or chasing first commercial traction, the leap from concept to meaningful funding rounds remains exceptionally steep. The report highlights a critical shortage of pre-seed and seed capital, alongside limited access to affordable debt for working capital needs.
