From school to Dragon's Den

Mark Champkins, entrepreneur and designer of Concentrate products, started inventing things at an early age, before going on to study engineering and design. A research secondment as part of his design course inspired him to develop products intended to help children concentrate and perform better at school.

This in turn led him to form his company, come to John Lewis to sell us his ideas, and to go on the BBC's Dragons' Den to seek funding, where he secured Peter Jones as an investment partner. It's an interesting story, as well as a great product – find out more in Mark's video profile.
