Our read

The Hub verdict

Mystery Jersey King asked for 50,000 pounds in return for 15%, a tidy split that values the sports-jersey brand at just over 333,000 pounds. Alex Street held that line, and Sara Davies came in on precisely those terms. Fifteen percent is a founder-friendly give: enough to bring a Dragon meaningfully on board while keeping the lion's share of the company in Street's hands. That balance of a modest equity slice against a six-figure valuation is often the mark of a pitch confident in its own traction. It is a 2025 season 22 pitch, one of the newest in the file, and Davies coming in alone on those terms suggests she saw a brand that already worked rather than one needing rebuilding.
