We are DATAbility – a curious, knowledge-driven start-up for software and technology solutions. As a spin-off of the Institute of Flight Systems and Control Engineering at the Technische Universität Darmstadt, we were founded in 2018. Our focus is on the analysis of big datasets, models for diagnosis and prognosis, as well as automated recommendations for action. What makes us special is the fusion of engineering and systems knowledge with data science and big data algorithms.
