Can a pair of smart shorts help elite athletes train smarter and avoid injury? Theo Health thinks so and golfer Xander Schauffele is backing the vision
Theo Health is at the forefront of a new category: smart activewear that tracks movement, delivers insights and helps prevent injury in elite athletes. The Glasgow-based sports tech startup has raised £1.2 million and brought on world No. 3 golfer Xander Schauffele as both investor and early product tester.
Schauffele, an Olympic gold medalist, is among the first “Alpha Athletes” trialing Theo’s flagship product, Theo Alpha Shorts, a pair of high-performance compression shorts embedded with inertial measurement units. The shorts link to a compact module that captures real-time data on reps, form and symmetry, insights that are typically limited to lab environments.
Behind the startup is founder and CEO Jodie Sinclair, a former soccer standout whose own athletic career was cut short by an ACL tear. The injury sidelined her for three years, ending her competitive career and ultimately inspiring the creation of Theo Health.
“There was no feedback during my recovery – I had no way of knowing if I was doing the right thing, or making it worse,” Sinclair said. “Theo is the system I wish I had when I was injured, one that makes recovery measurable, progress visible and elite performance possible again.”
Sinclair noted that Theo Health is also addressing the gender data gap in sports, where female athletes face a much higher risk of ACL injuries yet remain underrepresented in research.
“Theo is the first smart-clothing system truly built with female physiology in mind – without compromising on performance,” Sinclair said.
The startup had spent the past two years in stealth mode, focusing on IP protection, product development and team building.
“It’s great to now be back in the spotlight,” Sinclair added.
David Sundberg, Schauffele’s personal trainer, said he was impressed by the innovation and depth of data the system delivers.
“It all makes sense – I didn’t expect it to be this easy to understand,” he said. “These components help with form, others with strength, and others with speed. It’s simple for the athlete, but there’s so much information underneath.”
Dr. Cordelia Carter, Theo Health’s medical advisor and an orthopedic sports surgeon, said the stakes for athletes couldn’t be higher.
“I have treated many young athletes whose careers have been irrevocably changed — or ended — by injuries like an ACL tear,” she said. “Offering a tool that empowers athletes to make data-based decisions regarding their training, performance and injury prevention strategies is a true game-changer. This is Theo’s mission.”
The startup is now gearing up for its Alpha launch, a controlled testing phase with a select group of elite athletes and coaches. Beta pilots with one of the top European football clubs are also in the pipeline, with a broader market debut expected by summer 2027.
“The Alpha Shorts are just the beginning,” Sinclair said. “We’re building a product line designed to deliver full-body analysis, support athlete longevity and unlock applications far beyond sport.”
