The Story of STEP begins at the Institute of Chemical Engineering Aachen, where Dr.-Ing. Süleyman Yüce and Dr.-Ing. Joachim Gebel, each received a doctor’s degree from RWTH Aachen University for their scientific work with Prof. Dr.-Ing. Robert Rautenbach.

Dr.-Ing. Süleyman Yüce and Dr.-Ing. Joachim Gebel founded STEP located at the Oppenhoffallee in Aachen in 1996. Prof. Dr.-Ing. Rautenbach was head of the former Institute of Chemical Engineering for more than 30 years. After having been given emeritus status in 1996, he joined STEP as partner in 1998 until his passing in 2000.

In 2009, Step moved to the current address in the Eupener Straße in Aachen. Dr.-Ing. Joachim Gebel followed the call as a professor at the university of applied sciences Rhein-Waal in 2011 and left the company in 2016. Since 2016, Dr. Yüce is the managing director as well as sole shareholder of the STEP Consulting GmbH.
