The Beahon brothers once aspired to be professional sportsmen. Tom played football for Tranmere Rovers while his younger brother Phil represented Lancashire in cricket. The frustration of not making the grade on the field has made the pair even more determined to make a success of Castore. Former tennis ace Andy Murray was an early backer of their Manchester-based sportswear label and before long, their kit was being worn by England cricketers, top rugby clubs and the Oracle Red Bull Formula One team. A fundraising in late 2023 valued the business at just shy of £1bn. Since then, sales have continued to grow and there is now talk of an IPO.
