After 24 hours of work the participants presented their solutions to the jury, which included, in addition to IBM’s TJ-Bot, Dr. Henrik Hahn (3rd from left), Chief Digital Officer of Evonik, Dr. Bettina Uhlich (right), Chief Information Officer of Evonik, Thomas Schiffer (2nd from right), Head of Process and IT Management at Technology & Infrastructure, Torben Weis (3rd from right), Professor of Distributed Systems at the University of Duisburg Essen, Ethan Hermon (left), IBM, and Matthias Zarzecki (2nd from left), a hackathon veteran with more than 100 hackathons under his belt. The jury was evidently very impressed; as Hahn summed it up: “Everyone in his or her own way has presented great solutions.”
