About KEYOU GmbH

KEYOU is a successful clean mobility company from Munich that has been developing innovative hydrogen technologies since 2015, which allow conventional engines to be cost-efficiently transformed into emission-free hydrogen engines – without major modifications to the base engine. Based on engine conversion and integration of an H2 tank system, KEYOU offers its customers climate-neutral hydrogen vehicles that provide emission-free operation, efficiency, and cost-effectiveness simultaneously – without compromises in performance, capacity, and range. Beyond pure conversion and a CO2-free “second life” for existing vehicles, KEYOU is pursuing a comprehensive hydrogen mobility solution with its “Hydrogen Mobility as a Service” approach. The package ranges from vehicle and engine conversion, through fuel and infrastructure provision, to insurance as well as service and maintenance. “Zero emission mobility” becomes a reality with KEYOU.

MyAutoData (MAUD)

MyAutoData (MAUD) develops a new generation of mobility and AI platforms where drivers retain control over their own vehicle and mobility data. Through the MAUD Mobility Co-Pilot and the personal MAUD Data Vault, users can securely manage trips, driving behavior, vehicle costs, CO₂ emissions, service histories, and other mobility data, and selectively share it for personalized services. MAUD combines data protection, artificial intelligence, and data-based rewards into a new mobility model: Drivers benefit from safe and environmentally friendly driving through rewards, better offers, and data-based value – while companies, cities, insurers, and mobility providers can access voluntarily shared, high-quality mobility data. MAUD’s vision is a fair and transparent mobility data economy where mobility data is not controlled exclusively by corporations, but for the first time belongs to the driver themselves and can be used to their advantage. The underlying technology is “Patent Pending” with the USPTO and a legally validated innovation on the global market.
