Startup Partners in Performance: How a Scientist and a Strategist Turned a Wearable Idea into a Global Fitness Movement
Aug 5, 2025 | By Kailee Rainse

Raj Thiruchelvarajah and Dr. Warren Bradley had a shared obsession: making performance-enhancing science accessible to everyone—and that’s exactly what they set out to do with Hytro.
They came from very different worlds, Raj from the structured world of consulting and business, and Warren from elite sport and science. But both shared a deep interest in maximizing human performance.
Warren, an exercise scientist with a Doctorate in Exercise Physiology who has spent years working with elite athletes to find safe ways to push the limits of human performance.
Motivated by a desire to solve real societal challenges, Raj saw the need that was evident in the uptick of people searching for practical and scientifically grounded fitness tools.

The Moment That Ignited a Movement Toward Smarter Training
While working in elite sport, Warren saw firsthand how powerful Blood Flow Restriction (BFR) training could be. But traditional BFR methods were complicated, intimidating, and often misused—requiring professional supervision to avoid risk.
Most people couldn't access its benefits. Together, Raj and Warren realized they could build something that changed that: a wearable that made BFR simple, safe, and scalable for everyday use.
Quitting the Safe Path to Bring Science to Life
Raj had a promising consulting career, but he knew that if they were serious about Hytro, he'd have to leave the comfort of corporate life. Warren had already invested years into the science, and it was time to bring that research to life.
They leaped, leaving behind stable roles to co-found Hytro, a company focused on translating advanced sports science into wearable, user-friendly products.
Hytro’s First Step Toward Everyday Performance
The first version of Hytro's BFR wearables was built to test a simple idea: that people beyond elite sport could use BFR confidently and consistently.
Early feedback from athletes and fitness enthusiasts confirmed it—when the design is simple, the science solid, and the product comfortable, people engage. That early validation was the green light they needed.
Hytro Turned Resistance into Refinement
It was a hard task to build something new and create the category. After that, they had supply chain problems and all the inevitable startup challenges, with the added burden of scientific skepticism. Educating the market on BFR's benefits and gaining trust in a product they created took time.
But over time, each challenge became a valuable stepping stone, helping the team better understand the market and refine their approach with clarity and confidence.

The Breakthrough That Changed Everything
It was with the appearance of Hytro that names like rugby, football and mixed martial arts professionals were using the product had begun to emerge. That was the feedback that Hytro used to build out its definition as a performance-space solution.
These endorsements were also highly influential as they lead to considerable brand exposure and hurled us onto the map as a performance based product for strategic partnerships.
Building for More Than Just Athletes
With strong momentum, Hytro began scaling operations. Their product moved beyond elite locker rooms into home gyms, physiotherapy clinics, and fitness communities.
Raj and Warren expanded their team, invested in R&D, and built out a clear roadmap—launching new variations of the product to serve different needs, from recovery to rehab.

A New Era of Everyday Performance
Hytro's mission goes beyond fitness gear. They are on a mission to democratize the most modern performance science and changing the way that teams approach training for the future.
Hytro has been created to bring professional athlete level support and technology directly into the hands of anyone else looking for an edge, whether a pro pushing physical limits or weekend warrior desiring fast recovery.
A Culture Built on Growth, Grit, and Bold Ideas
Raj is a bold visionary, he knows what it means to invest in big bets. Warren is one of the rockets attached to the innovation engine, rooted in science and fueled by curiosity.
As a result, they’ve created a culture of inquiry—where every voice is valued and experimentation is encouraged. The Hytro workspace blends performance-driven ambition with the agility and momentum of a fast-paced startup.
Words to Future Founders
For those looking to build something meaningful, Raj and Warren emphasize one thing: solve a problem that matters, and don't underestimate the value of timing.
They believe that consistency beats intensity—and that building trust, both inside and outside the team, is what sustains a startup through its toughest days.
The Road Ahead
Hytro is only getting started. With plans to grow across Europe and dive deeper into wellness and rehab, the team is pushing boundaries with new product lines, smart partnerships in sport, and AI-driven personalization. But through it all, their mission stays the same—bringing performance-enhancing science within reach for everyone, not just elite athletes.
