Look for Concentrate Design on AmazonFull story →Mark Champkins turned a year spent studying how classroom layout affects a child's ability to focus into a line of products meant to fix the problem directly, an unusual research-first pitch for the Den.
Both the founder and the product line remain active by the public record.
The Terms
Champkins wanted £100,000 for 40 percent of the company, a large stake reflecting just how early the business still was: one founder, a body of research, and an idea still waiting to become a full product range.
Peter Jones backed the full amount, in keeping with his habit of committing early to a founder before the commercial case is fully proven, provided the underlying insight feels genuinely new.
Trust Takes Time In This Market
Buyers in education move cautiously, wanting proof before adopting anything new, but a supplier that earns that trust tends to keep the relationship for years since schools rarely swap suppliers on a whim.
That patience likely shaped how Champkins expanded the business, favouring steady product releases over any attempt at rapid scale.
The Portfolio Kept Growing
Champkins's own account of his design career describes launching more than a dozen further products under the Concentrate name, part of a broader body of work spanning over fifty products across his career.
His personal portfolio still lists Concentrate as active work, which points to a business that kept building rather than one that stalled after its television appearance.
