Since appearing on BBC’s Dragons’ Den in January 2025, Alex Street, founder of Mystery Jersey King, has seen his business skyrocket, with sales more than doubling and growth hitting record levels.
Mystery Jersey King is the surprise-box brand giving football fans a thrill with every order. Customers receive an authentic jersey at random, often from top leagues and clubs around the world, creating a unique blend of excitement, collectability, and community spirit.
For Alex, the Dragons’ Den experience was transformative. He says: “The show proved that Mystery Jersey King is both authentic and high-quality, and the credibility of Dragons’ Den gave me the confidence to fully believe in myself as an entrepreneur.”
Since the episode aired, the business has partnered with leading manufacturers and brands, launched exclusive activations and free gift incentives, and secured high-profile endorsements from celebrities and athletes including KSI, darts star Luke Littler, and Lioness, Chloe Kelly.
Mystery Jersey King has also deepened its community focus, creating a sense of belonging for collectors, gamers, casual players, and fashion enthusiasts alike.
Alex credits much of the business’s rapid progress to Dragon investor Sara Davies. “Sara is creative, operationally sharp, and full of blinding ideas. She’s helped us refine our strategy, introduce systems that improve customer experience, and scale the business as we prepare for the American World Cup.”
Expanding the product range, Mystery Jersey King has launched share boxes for groups and stag dos, a retro outlet offering vintage investment shirts, and exclusive gifts, including cards and scarves.
Beyond business, one of Alex’s proudest personal highlights this year has been taking over coaching duties for the Eastwood CFC Under-12 Girls Team. Sara Davies even sent the team a personal message, praising them as “courageous”.
The Dragons’ Den effect has been clear: since January 2025, Mystery Jersey King has seen dramatic growth, with website traffic up 66%, revenue up 164%, and orders up 165%. With a record-breaking year behind him, Alex is excited about the future: “We’re growing, we’re confident, and we’re ready for what’s next. Dragons’ Den was a life-changing experience, and I wouldn’t change a thing.”
