Stratosphere builds upon the legacy of Critical Materials. A Start-up kicked-off operations in 2009 based on a joint vision of Critical Group and two researchers from the University of Minho / PIEP. Critical Group provided go-to-market support while the two individual founders contributed with a large experience in advanced critical applications of materials and structures. During 2019 an MBO leaded by the founders of the company transformed Critical Materials S.A into Stratosphere S.A. The company maintains the same disruptive DNA and redefines its focus to become a leading Global Provider of Advanced Cyberphysical Systems. The main product PRODDIA™ is an innovative structural health monitoring and management system with applications across several High Demanding Markets. We provide integrated health & monitoring solutions to current and future challenges in our focus industries: Aeronautics, Space, Defence, Energy and Infrastructures.
