In a world obsessed with AI and blockchain, Koolboks is building a billion-dollar business on the back of a 1980s technology: the chest freezer. But they’ve grafted it onto a modern, subscription-based solar engine, creating a product that is radically accessible to the off-grid African market.

"They aren't selling hardware; they are selling the ability to keep food cold without a grid, and they are doing it at scale."

The company’s leadership, including Chief Business Officer Natalie Casey and Chief Global Expansion Officer Nicolas Folliot, signals a focus on scaling operations beyond Nigeria. The tech stack—relying on jQuery, Tailwind CSS, and Bootstrap—indicates a pragmatic approach: functional, lightweight, and optimized for regions with potentially slower internet connections, rather than chasing bleeding-edge frontend frameworks.

• Asset-backed financing model: The freezer is the collateral.
• Scalable hardware: Uses standard chest freezer designs modified for solar.
• Local presence: Strong social media footprint (Facebook, Instagram) tailored to Nigerian demographics.
