marcel Beltran CEO & Inventor of the French Kart


CEO & Inventor of the Overjump

Marcel Beltran has a diploma in cycles and motorcycles Mechanics and has always been passionate about this universe. Also a nature lover, he has been farming animals for 15 years without abandoning his primary passion for mechanics and inventions of all kinds. Passion for which he devoted his free time until the invention of the “Overjump”. Father of two, he created the very first French Kart -then called “Tailleur Kart” (Cross-legged Kart) - for the entertainment of his children based on one of his fondest childhood memories.

Jean-Michel Berthomieu

CFO & Co-funder of the Overjump

Chartered accountant and former head of the accounting firm ``JM Berthomieu`` composed of ten employees. He leaves the accounting world after sixteen years of experience to devote himself to several start-ups with notably the company ``Transactionis``, the ``Adamentis Group`` and today the Start-up ``OVERJUMP`` where the association with Marcel Beltran appeared as an evidence for him.

The origins of the Overjump

The origin of the Overjump goes back to 2012, in the south of France. Marcel, its creator, invented the very first Overjump – then called “Tailleur Kart” (Cross-legged Kart) – based on one of his fondest childhood memories for the entertainment of his son. As a child, he enjoyed going down the slopes of his village while sitting on his skateboard with his friends.

And thus was born the idea of the Overjump which led him to create the first prototype. In light of its success, even among the adults who tried it, Marcel decided to refine his invention -while retaining its signature cross-legged posture- so he, his family and his friends could have fun competing together.

6 years on, an incalculable number of hours of work and a dozen hand-made prototypes later, Marcel had created the final model of his invention: the “Overjump”, the first cross-legged, all-terrain, electric Kart.
