Founding Story

Forced to adapt his workout routine during the pandemic, our founder Jonathan Montet discovered a major flaw with modern Pilates reformers. You have to rotate 180 degrees to complete a full-body workout. This makes it impossible to safely follow a digital instructor without having to spend time looking over your shoulder, taking your body out of proper alignment, risking injury.

This Ah-Ha moment led Jonathan to create ONYX, the world’s first reformer with forward-facing motion throughout your entire workout. Jonathan created ONYX’s patent-pending dual directional technology allowing you to complete a full-body workout from start to finish, never having to turn your back to your digital instructor. But he didn’t stop there. In addition to the dual-directional technology, ONYX has a hybrid functionally of a classical reformer and the more advanced megarefomers making it the perfect reformer no matter your experience level. With its module design, you get a full-sized reformer's functionality with the benefits of a smaller foldable reformer. The ONYX reformer can easily be broken down and stored in less than one square foot of space.

A self-proclaimed techie and data junkie Jonathan also noticed leading online programs in the Pilates and functional wellness space have yet to incorporate AI technology into their platforms. With the hardware issues now solved, he created the ONYX Studio, an online platform that combines world-class instructors with AI-enabled form correction technology. The ONYX studio provides members with a best-in-class personalized experience for all fitness levels and abilities.

"The machine is super cool, it’s sleek and what I love about is that it’s compact and can fit easily in your home. I’ve done Pilates and the tower, but the technology on ONYX is awesome for Pilates, and the fact you can have it in your house - very cool"
