At Rayofi, we believe time is a luxury—so we create smarter tools to help you make the most of it.
We’re Johnny and Benita—two athletes with a love for endurance sports but not always for the gym. As a triathlete, Johnny spends countless hours running, biking, and swimming. And Benita? She’s passionate about running, but strength training was never her favorite part. Still, we both knew how important it is to stay strong and balanced.
That’s why we set out to find a better way to fit strength training into our busy lives—without sacrificing the time and energy we want to dedicate to our sport.
Together, we came up with the idea for the GoTone Portable Gym Machine.
It had to be compact, powerful, and easy to use anywhere—at home, in the garden, even while traveling. We built the first prototype ourselves and tested it relentlessly. From there, we improved and refined version after version until we got to where we are today: a reliable and effective device that helps us, and now many others, build muscle and stay injury-free—without needing to go to the gym.
But that wasn’t the only challenge we wanted to solve.
Swimming has always been the toughest part of Johnny’s training—not just physically, but mentally. Long hours in the pool can feel repetitive, and real-time coaching was nearly impossible. That’s how the idea for the SwimmComm Earphones was born. These waterproof earphones connect to a radio transmitter that streams music or coaching while swimming. For the first time, Johnny could get feedback mid-lap and enjoy his sessions more—no Bluetooth, no interruptions.
That’s what Rayofi is all about.
We use technology to make training more efficient, more flexible, and more fun. Whether you’re a triathlete, a runner, a cyclist, or someone just trying to stay fit—our goal is to help you train smarter, not harder.
And we’re just getting started.
Join us on the journey.
