Our Story

DeFuTech was founded as a spin-off from one of the largest Applied Research Institutes in Europe (Fraunhofer Institute) in 2014. Our first task was to convert WiBACK – the Wireless Backhaul technology of Fraunhofer FOKUS – into a product for global adoption. Today, DeFuTech has deployed WiBACK in Africa, Asia, South America and Europe connecting rural regions to the Internet – at comparatively low cost. In addition to the marketing of current products, DeFuTech participates in Research and Development (R&D) projects and consultancy services. Prof. Karl Jonas, Dr. Mathias Kretschmer and Jens Mödeker sit on the advisory board.
