Our read
The Hub verdict
At £25,000, Eco Spot carried one of the smallest asks you will find in the Den, John Boff offering 35 percent of his adjustable bricklayer's mortarboard for it, a valuation of about £71,429. Small asks like this tend to be less about the cash and more about pulling a Dragon's industry contacts toward a very practical trade product.
The record shows he left with a deal, though the episode kept the final numbers off screen, so this sits in the undisclosed column. We can walk you through the entry point, 35 percent for £25,000, and we stop there rather than inventing the close. Whether the tool reached the merchants it was built for is a separate matter we have not verified.
A tiny ask for a very practical trade tool, terms left unsaid.
Worth knowing: The deal above is public record from the episode. We never treat an on-air handshake as proof a product is still for sale today.
