Limitless body, boundless life
The story behind RheoFit
Dear friends,
Hello, I’m Adam, the founder of RheoFit. Today, I’m excited to share the story behind RheoFit, a journey driven by passion, innovation, and the determination to create real value for every user.
A Lifelong Passion for Robotics and Sports
From a young age, I’ve been passionate about two things: robotics and sports. In high school, I spent countless hours in the robotics lab, exploring new design ideas with my teammates. At the same time, I was an avid athlete, running laps on the track and feeling energized after every workout. Running 15 laps would leave me pumped and ready to take on life’s challenges. One day, I met Dr. Wang, a director at Texas Instruments. Despite being nearly 50, he was incredibly energetic. I later learned that he participated in nearly ten marathons every year, which he credited for keeping both his body and mind sharp. Inspired by him, I decided to take on my first half marathon.
Driven by innovation
The Road to RheoFit
Since I started running, post-run muscle soreness became my "best friend". I was recommended massage guns and foam rollers, but after a long run, I just didn’t have the energy to use them properly. Trying to reach my quads, hips, and back meant twisting into awkward positions. Moreover, some muscles barely got any relief, while others felt even more tired. The most confusing part to me was what areas to focus on, for how long, or how intense the massage should be.
Performance driven
The Spark of Inspiration
Upon frustration with existing solutions, I thought to myself: why not build something that actually solves this? With years of experience in robotics, I saw an opportunity. By combining smart design with smart sensor algorisms, I could create a device that takes the guesswork and effort out of recovery. The RheoFit idea went from a concept to reality since then.
A Dream Takes Flight
Together with my robotics team, we began developing a prototype and testing it with runners in the park.
Innovation Beyond Limits
Creating the RheoFit A1 has been anything but easy. Its compact form and structural design presented major engineering challenges, for both our design team and for manufacturers. We went through 255 iterations, carefully fine-tuning every detail to ensure the final product feels intuitive, effective, and comfortable to use.
The real breakthrough came with the integration of our in-house RheoAI technology. Trained on real-world data, it analyzes your body’s weight distribution to deliver personalized massage recommendations, removing the guesswork and making recovery smarter and more tailored to you.
The Challenge of Mass Production
It’s one thing to build a prototype, but it’s a whole different challenge to mass-produce hundreds of them. Manufacturing hardware at scale turned out even tougher than we anticipated. From quality control to logistics to building our direct-to-consumer team from scratch, every step pushed us to our limits.
But the hard work paid off. Within just two months of launch, we sold nearly 3,000 units across Europe and the U.S., proving that RheoFit was meeting a real need.
Full Steam Ahead
At RheoFit, we work relentlessly, fine-tuning every design detail, testing ideas again and again, and always pushing ourselves to do better. We know that one thing remains clear: the best way to grow is by listening to our users. You're not just a customer, you're a co-creator, a vital part of our team helping us evolve and shape future product liness. Your feedback shapes our journey and gives us the reason to keep moving forward.
