FinX develops and licenses an innovative nautical propulsion technology, which replaces the propeller with an undulating membrane, inspired by fish.

The patented FinX technology uses a flexible diaphragm, whose undulation, like a fish's fin, propels the water with greater energy efficiency (applied to industrial pumps, the energy saving is 30% compared to a propeller with the same speed, which is very promising for pleasure boats, expedition boats and tomorrow's autonomous boats). It is therefore not only more economical but also quieter and less dangerous for humans and biodiversity.

FinXas it sounds, is using an impressive bioinspired technology to propel boats a fin, undulating like a fish, replacing the old propeller technology.

More efficient, almost maintenance free, and totally safe... here are some advantages of our amazing technology!

JULY 2019, FinX had the honour of presenting its biomimetic boat propulsion technology to His Serene Highness Prince Albert II of Monaco, at the Monaco Solar & Energy Boat Challenge!

JUNE 2019, meeting with Brune Poirson, Secretary of State for Ecological and Solidarity Transition, at the INTERNATIONAL CLEANTECH WEEK exhibition in Annecy where FinX was invited to pitch on its wave fin boat engine technology.

MAY 2019, Thank you ParisSaclaySPRING and CCIEssonne for the first pitchcontest prize awarded! Thank you Cedric Villani for inspiring entrepreneurs!

Thank you also to all the partners of this successful event for your support and your gifts, especially Airbus, CréditAgricole and Fidal.
