The 2n8life GmbH develops a user-friendly system for measuring nocturnal erections including an app for visualizing the results. A textile cuff is worn overnight by the man. It measures erections and sends them via Bluetooth to the smartphone. In the app, the user sees his results in the context of the comparison group. The main applications are differential diagnostics for erectile dysfunction (organic or psychological causes) and use as a digital biomarker for cardiovascular diseases.

Airgonomics is an AI-based solution for analyzing physical strain at industrial workplaces. Using camera-based motion capture, we identify ergonomic risks such as repetitive movements, poor posture, and high physical strain in real working environments. This helps companies in manufacturing and logistics reduce musculoskeletal disorders, improve workplaces strategically, and implement ergonomics in a scalable, data-driven, and practical manner. Our approach creates greater transparency around actual strain situations in everyday work and enables improvements to be made where they have the greatest impact on health, work ability, and workplace quality.

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.
