Global climate finance for Africa has grown significantly over the past decade.
Large-scale solar farms, national grid projects, and established clean energy businesses can now access institutional capital with relative ease.
The problem sits one layer below: the early-stage, locally owned renewable energy and clean cooking companies that are too small for large funds and too risky for commercial lenders.
This is the gap that Hummingbird One was built to fill.
What Hummingbird One Is
Hummingbird One is a blended finance debt vehicle launched by Charm Impact, a London-based clean energy financier founded in 2018, with a track record of deploying $5.4 million across more than 40 loans in eight African markets reaching over 350,000 people with improved energy access.
The fund reached its first close at USD 6.25 million against a target size of USD 12 million, with backing from Oikocredit, the Dutch Good Growth Fund’s Seed Capital and Business Development facility (managed by Triple Jump), the IKEA Foundation, and the Good Energies Foundation.
It provides small-ticket loans ranging from USD 50,000 to USD 500,000, precisely the ticket sizes that larger institutional funds cannot deploy efficiently to locally rooted businesses across Kenya, Uganda, Nigeria, and Zambia. At least 85% of the portfolio will consist of locally owned companies.
Its first investment has already been made: Megawatt Energies, a Kenyan renewable energy equipment aggregator.
The Structural Problem It Is Solving
The “missing middle” in African climate finance is well documented but poorly addressed.
Early-stage clean energy companies need patient, repeat capital to build operational track records.
Without those track records, they cannot access the institutional funding that would allow them to scale. Without scale, they cannot build the track records.

Charm Impact CEO Gavriel Landau identified this structural mismatch directly: “The renewable energy ecosystem is becoming increasingly effective at funding established scale. But it has not been designed to finance scale-building.”
Selina Yang of Oikocredit reinforced the point from the investor side: “Early-stage companies are essential to a thriving sustainable energy ecosystem in Africa, yet they often fall below the ticket sizes that larger institutions can efficiently support.”
How the Blended Finance Structure Works
Hummingbird One operates as a tiered blended finance vehicle: stacking senior, junior, and catalytic capital to balance risk and return across investor types.
The junior and catalytic tranches absorb higher risk, creating a buffer that allows more risk-averse senior institutional investors to participate.
This structure is not new, but its application at the $50,000–$500,000 ticket size is rare.
Most blended finance vehicles in African climate finance operate at significantly larger deal sizes, leaving the earliest-stage market chronically underserved.
Charm Impact has also developed custom software to accelerate credit assessment and continuous portfolio monitoring, reducing due diligence timelines from years to months.
This technology layer is what makes the economics of small-ticket lending at institutional quality viable.
Why Repeat Financing Matters
One of Hummingbird One’s most distinctive design features is its emphasis on repeat financing and ongoing engagement.
Rather than providing a single loan and exiting, the vehicle is structured to offer continuity of capital as companies grow, therefore allowing businesses to progress from early-stage borrower to institutionally bankable enterprise without falling through funding gaps along the way.
This graduation pathway is arguably more valuable than any individual loan.
It transforms Hummingbird One from a gap-filler into a pipeline builder for the broader African climate finance ecosystem.
The Bottom Line
Hummingbird One will not single-handedly close Africa’s early-stage climate finance gap since no single vehicle can.
But it demonstrates that the gap is financeable, that locally owned companies are creditworthy at the right ticket size, and that blended finance structures can be designed to serve the market’s earliest and most underserved layer.
