The Arion HST's Team

The founder.

Sylvain Houry, founder and president of Arion HST.

It was in California, where Sylvain was hired as a sales manager for a saddlery house, that the idea of Arion was floating around in his head. The American dream became a reality in 2018 when he created Arion Horse Sport Tack and marketed accessories. But Sylvain wants to go further to meet the requirements of the world’s best riders and improve the well-being of horses. True to his influences and values, he and Hadrien succeeded in combining innovation, comfort and the “French touch” to launch a first collection of high-end sport saddles in 2020, first in the United States, then in France a few months later.

“My passion for luxury products and French craftsmanship, as well as for horseback riding and the people I have met, made me want to create my own brand; marked by authenticity, quality and innovation.”
Enthralled by horseback riding from a very young age, Sylvain quickly imagined himself becoming a world champion. However, he decided to stop when he was a teenager. Admiring his twin brother’s results, he got back in the saddle and quickly acquired a good level. His perseverance and ambition lead him to the Pro 1 level of the French CCE championships, in parallel with his studies in a major French business school.

After entering the workforce, the equestrian competition fades in favour of his professional career which leads him across the Atlantic. Driven by his boldness and passion, Sylvain skillfully juggles emotion, balance and energy like any good rider. The French entrepreneur, now based in Florida, also shows insight and precision to drive the movement and become one with his teams, like the osmosis formed by the rider and his horse.

What does he likes? The thirst for discovery.

In addition to horseback riding, Sylvain practices a multitude of sports: wake boarding, tennis, golf, swimming, yoga, pilates, soccer, running… His insatiable curiosity also pushes him to travel the world and to get off the beaten track. Hyperactive and nature lover, Sylvain also loves to take care of his garden, when he is not behind the stove cooking good food.

Hadrien Schenck, inspiring director, responsible for sales within the Arion Sellier France team.

As general manager, Hadrien holds the reins of Arion with passion and perseverance. Supported by his team of saddlery expert consultants, he is also responsible for sales in France. Naturally empathetic and eager for challenges, Hadrien never ceases to fulfill the wishes of Arion’s customers, so that the rider feels the mechanics of his mount and the horse is happy and free to move.

“Dedicated to the comfort, well-being and performance of the horse, we use 100% of our energy to satisfy you”
Entrepreneur, perfectionist and competitor at heart, this former high-level eventing rider has always flirted with the equestrian world. He started out as a horse trainer in Bordeaux, working alongside world and Olympic vice-champion CĂ©dric Lyard. He then managed an owner’s stable in the Tarn region of France, before embarking on a commercial career. After selling saddles for a prestigious French company and horse transport vehicles for an English brand, he returned to the world of equestrian sports to represent Arion Sellier France.

His hobby? The thrill of it all.

In search of adrenaline, Hadrien enjoys mountain biking, snowboarding and wake boarding. He is a former riding instructor, and is also the proud father of two children. As everyone knows, being a parent is often a sport! Born in the South-West of France, Hadrien is an epicurien with an overflowing enthusiasm, who likes to share convivial and festive moments with family and friends.
