About STABL Energy GmbH

STABL Energy GmbH develops energy storage systems from retired vehicle batteries. The goal is to increase the use of renewable energies with the help of energy storage while extending the lifecycle of car batteries. This reduces dependence on fossil fuels and enables longer use of batteries that contribute to the success of the energy transition. To achieve this, the company sets a new standard in design, safety, reliability, cost efficiency, and battery storage handling with its innovative, integrable technology. First choice for second life STABL’s technology can connect batteries with different residual capacities in large quantities to the public power grid without a central inverter. The advantages of the innovative technology are diverse: second-life storage from sorted-out e-car batteries is a promising way to extend battery life and reduce their ecological footprint. Second-life batteries can also help reduce the costs of renewable energies and improve the integration of solar and wind energy into the power grid. STABL realized its first projects together with partners in Germany and Switzerland. STABL was founded in 2019 by Dr. Arthur Singer, Dr. Nam Truong, Martin Sprehe, and Christoph Dietrich, four visionary engineers from TU München, Universität der Bundeswehr München, and Osnabrück University of Applied Sciences. The startup has since experienced solid growth: starting with a small group of founders, the company now employs almost 30 full-time employees and around 20 student assistants.

ARCIS

ARCIS builds an AI-powered decision layer for logistics and freight operations. Many logistics teams today still work with fragmented processes across TMS systems, Excel files, emails, PDFs, and the individual experience of dispatchers. This results in manual work, slow handoffs, missing information, and inefficient planning decisions. ARCIS was founded by Onur Yılmaz and Birkan Kolcu, two computer engineers whose collaboration began 14 years ago as fellow students, roommates, and long-term technical partners. Onur combines computer science expertise, business-building experience, an MSc in Informatics from Technical University of Munich, experience at Intel, and strong connections to Munich’s startup ecosystem. Birkan brings technical depth from his computer science degree at the University of Arizona as well as practical experience in cloud engineering and scalable systems. The focus on logistics emerged from close relationships with logistics companies and operators in the team’s network. As these conversations increased, a recurring pattern became clear: high-quality operational decisions are still made manually across scattered systems and personal experience. ARCIS helps logistics teams connect this information and make decisions around dispatch planning, load-truck-driver matching, capacity utilization, document processes, and operational exceptions faster and more reliably—without replacing existing systems.
