Co-Founder · Industrial Engineer
Background in electronics and business administration. Years of experience in project management and in developing electric drives.
Specialists in e-mobility, hydrodynamics and embedded systems – united by the idea of gliding across the water silently and emission-free.
It all started on holiday: we were lying on the beach, enjoying the calm and the vastness of the sea – until a loud, foul-smelling personal watercraft broke the silence. Reason enough to change something. The idea was born: an electric water-jet drive like none before it.
Today, Sylents is one of the first manufacturers of electric jet drives for the leisure-boating segment – safe, blockage-free and emission-free.
