Reacnostics is a science and engineering company in the chemical industry, specializing in simulating, constructing, and building profile reactors for analyzing catalytic reactions. Their expertise lies in the crucial role of catalytic reactors in various industrial processes, ranging from fuel production to emission abatement and sustainable technologies like Power-to-X and Carbon2Chem. The company addresses the challenge of understanding and optimizing processes inside non-transparent and high-pressure catalytic reactors. Founded in 2017 and based in Germany, Reacnostics secured a Seed Round investment on 01 January 2018 from IFB Innovationsstarter. Reacnostics offers advanced technology in the field of operando analysis and optimization of catalytic reactors. As a spin-off of TU Hamburg, the company provides reactor hardware, measurement services, and modeling capabilities to help customers optimize their catalytic reactors based on knowledge. Their goal is to make the reactor "transparent" by measuring and modeling the concentration, temperature, and flow field inside the reactor and characterizing the local state of the catalyst by spatially resolved spectroscopy. The company's innovative approach and potential to revolutionize the understanding and optimization of catalytic reactors make it an intriguing prospect for venture capitalists seeking promising ventures in the construction and chemical industries. With a strong founding team and backing from reputable investors, Reacnostics is poised to make a significant impact in the field of chemical engineering and industrial processes.
