Launched by former Aston University students Ben Francis and Lewis Morgan in 2012, the business has taken up 7,814 sq ft at Unit 1, Brooklands, fronting Moons Moat Drive.
Gymshark now boasts 40-plus staff and customers in 160 countries, selling over the internet and competing with the likes of sportswear giants Adidas and Nike.
The brand offers a range of exercise apparel for men and women which has been developed and expanded to include the likes of workout t-shirts, gym bags, running jackets, stringer vests, hoodies and hex leggings – all emblazoned with Gymshark's distinctive shark logo.
Francis and Morgan co-founded the business when they were still teenagers, both are now directors along with managing director Steve Hewitt and strategic director Paul Richardson.
“Everyone involved with Gymshark – our supporters, our team and our athletes – form part of a huge community, a family,” said Francis.
“We promise to do the best we possibly can to help our family and these new premises reflect that while at the same time taking us to the next level.”
The move to a new headquarters, a deal put together by property agents John Truslove, comes ahead of a busy period for the Gymshark team.
Paul Richardson, strategic development director of Gymshark, said: “We will see £12m turnover this year and are aiming to raise that to £50m in the next five years.
“We chose Redditch because it has good motorway connections, many of our staff live in the area and the building offered room to grow.”
The new two storey building has been taken on a 10 year lease and will house design, e-commerce, administration and customer service staff.
Francis said: “It all began in a paint-stained back room at home, with a screen-printer bought with our combined savings. We are now talking thousands of square feet of office space and warehousing – quite a change.
“Yet, despite the success we have had I believe we still have a long way to go. I'm very excited about the future.”
