Koolboks, a Nigeria-born climate tech startup, has secured $11 million in fresh capital to accelerate the rollout of its solar-powered, IoT-enabled refrigeration units across Africa and other emerging markets. The round, a mix of equity and debt, was led by Nairobi-based KawiSafi Ventures, with follow-on support from Aruwa Capital Management and All On. Debt financing came from FFEM and Bpifrance, complemented by grants and results-based funding from Innovate UK, the Shell Foundation, and CEI Africa.
This injection follows a $2.5 million seed raise in 2022 and comes at a time when Africa’s “cooling crisis” is directly undermining food security, small business resilience, and public health.
Tackling Africa’s Cooling Crisis
For co-founder and chief executive Ayoola Dominic, the funding is about more than scale it is about survival for Africa’s micro-entrepreneurs.
“Every day, small business owners, especially women, face devastating losses when food spoils or diesel costs wipe out profits,” Dominic said. “Reliable cooling is not a luxury it is the difference between thriving and barely surviving.”
With more than 10,000 solar-powered freezers already deployed across 25 countries, Koolboks’ impact is visible at street markets, frozen food outlets, rural bars, and health clinics. The company’s units, equipped with IoT sensors, monitor temperature, energy use and door activity. Through a flexible pay-as-you-go (PAYGO) system, customers can lease refrigeration without heavy upfront costs a critical feature in cash-constrained communities.
Entrepreneurship Meets Inclusion
For co-founder Deborah Gael, the real story is the human multiplier effect. “When a woman has access to reliable cooling, she can safeguard her inventory, boost her income and reinvest in her family and community,” she noted. “It is not just technology, it is economic freedom.”
Koolboks has also introduced the Koolbuy platform, offering buy-now-pay-later (BNPL) financing for cooling products and Scrap4New, a recycling initiative that transforms discarded freezers into new IoT-enabled solar units. Both initiatives signal an intent to embed inclusivity and sustainability into its business model.
Climate Tech at the Crossroads of Empowerment
Africa loses an estimated $4 billion annually in post-harvest food losses due to inadequate cold storage, according to the UN. With climate change driving higher temperatures and unreliable grids leaving communities in the dark, the need for decentralized, clean cooling solutions has never been more urgent.
By tackling these dual challenges food insecurity and unreliable electricity, Koolboks positions itself at the intersection of climate resilience and entrepreneurship. The company’s approach demonstrates how climate tech can unlock productivity, safeguard livelihoods, and contribute to a just energy transition.
From Survival to Scale
The latest raise underscores a growing investor appetite for African climate ventures that deliver both financial returns and measurable impact. The involvement of local investors like KawiSafi Ventures alongside international development financiers highlights a shift towards blended finance models tailored for African innovation.
Koolboks now faces the challenge of scaling distribution while navigating fragmented markets and regulatory environments. Yet if successful, its model could set a precedent for other African entrepreneurs seeking to fuse climate innovation with inclusive business design.
