Two Ghanaian startups, Freezelink and Revna Biosciences, have been listed on Bloomberg’s inaugural list of 25 innovative African startups to watch in 2025.

Founded by Owusu Akoto​​ in 2018, FreezeLink is solving a major challenge in Africa’s agriculture and healthcare sectors—inefficient cold chain logistics. Significant losses occur in many parts of the continent due to the lack of reliable temperature-controlled storage and transport systems, affecting everything from fresh produce to life-saving vaccines. FreezeLink tackles this issue by providing end-to-end cold chain solutions, including solar-powered cold storage, refrigerated delivery, and real-time temperature monitoring. By making these services accessible through flexible, cost-effective models, FreezeLink helps smallholder farmers, food distributors, and health providers preserve product quality, reduce waste, and expand market reach.

Revna Biosciences is addressing the critical need for advanced molecular diagnostics and personalized healthcare in Sub-Saharan Africa. Led by Dr. Derrick Edem Akpalu, the company is pioneering precision medicine by integrating genomic sequencing, biomarker analysis, and molecular profiling to tailor treatments to individual genetic profiles. This approach is particularly impactful in managing diseases prevalent in the region, such as cancer, malaria, and diabetes. Revna’s state-of-the-art laboratory, the first in West Africa to achieve dual ISO accreditations for clinical diagnostics and biobanking, underscores its commitment to quality and innovation. Through strategic partnerships with global biotech leaders like QIAGEN and AstraZeneca, Revna is enhancing diagnostic capabilities and expanding access to targeted therapies.
