Early History

Koolboks was established in 2018 with the goal of revolutionizing access to refrigeration, especially in off-grid areas. It initially targeted European campers before pivoting to African markets, addressing the significant challenge of unreliable electricity in rural regions. The company introduced solar-powered freezers capable of operating without grid connections, leveraging ice battery technology for enhanced energy storage. This approach reduced the overall cost of cooling by 40% compared to traditional methods. Early on, Koolboks secured initial funding that allowed expansion into multiple African nations and collaboration with aid and development agencies to maximize its social impact.
