Koolboks develops solar-powered refrigeration technology for markets across Africa. The company's core product is a solar freezer that provides 24-hour cooling powered entirely by the sun, with the capability to maintain refrigeration for 4-7 days without sunlight. The units are used by over 10,000 customers, with thousands of freezers deployed across Nigeria, Kenya, Uganda, and France.
Operating at the intersection of renewable energy and clean technology, Koolboks combines hardware engineering with pay-as-you-go systems to make cooling accessible to micro-entrepreneurs and communities. The company secured $2.5 million in seed funding and won €50,000 in Galp's start-up global contest.
Technical work at Koolboks spans solar-powered cooling, renewable energy systems, and pay-as-you-go technology platforms - a stack that addresses both the energy access and financial inclusion dimensions of off-grid refrigeration.
