Hyperdrives (Munich, €3M pre-seed) invented a technique to channel dielectric coolant directly inside the copper windings of electric motors. The hollow-conductor cooling approach achieves continuous current density up to 3x higher than conventional motors — bringing motorsport-level performance to mass-market applications.
The breakthrough is manufacturability: hollow-conductor cooling has been known in lab settings but was considered impossible to produce at industrial scale. Hyperdrives' innovation is making this technique compatible with standard motor manufacturing processes, meaning the performance advantage can be achieved without exotic production methods.
The technology applies to industrial electrification (factory motors, agricultural equipment, mining vehicles) and autonomous vehicles. PROTOTYPE Capital backed the company, seeing it as part of the physical AI infrastructure layer: autonomous tractors (Voltrac), mining machines (Sensmore), and logistics robots all need more powerful, efficient motors. Germany's position as the world's largest motor manufacturer (Siemens, Bosch, Continental) provides both the engineering talent and the customer base for next-generation drive systems.
