3 T-Shirts to Millions

In a modest living room in Liverpool, two best friends, Daniel Yuen and Kieran Riddell, had a vision. It was 2019, and they noticed something missing in the sportswear market clothing that blended performance, style, and affordability. With no big investors or fancy offices, they decided to start small just 3 t-shirts. That humble beginning would grow into Montirex, one of the UK’s fastest-growing sportswear brands. Daniel and Kieran weren’t fashion moguls or business tycoons. They were just two regular guys who loved fitness and saw an opportunity. With less than £2,000 and a lot of late nights, they designed three t-shirts, ordered a small batch, and began selling them through Instagram and word of mouth. The brand’s clean design, active lifestyle appeal, and strong presence on social media caught people’s attention. Influencers, athletes, and everyday gym-goers started wearing Montirex gear, and demand quickly outpaced supply. They reinvested every pound they made into more stock, expanding slowly but smartly first with hoodies and shorts, then jackets and full collections. What made Montirex stand out was its connection to the community and its authentic roots. It wasn’t trying to compete with giants like Nike or Adidas it was built for real people, by real people. The brand’s popularity exploded, especially in the UK fitness scene. By 2023, just four years after launching, Montirex had become a multi-million-pound brand, collaborating with athletes and celebrities, opening pop-up stores, and distributing products across Europe. Despite their massive success, Daniel and Kieran have stayed grounded, often sharing how their journey began with just an idea, a tiny budget, and 3 simple t-shirts. Their story is a modern day example of what happens when passion meets persistence. In an age where startups often chase funding first, Montirex shows what can be achieved through vision, hustle, and heart. From a living room in Liverpool to a booming global brand, Daniel and Kieran didn’t just sell shirts they built a legacy.
