Emma Grede, the London-born CEO behind Good American and founding partner of SKIMS, is back as a guest Dragon! She joins Peter Jones, Deborah Meaden, Sara Davies, Steven Bartlett and Touker Suleyman as another batch of entrepreneurs attempt to conquer the Den. Two brothers running their business from Birmingham hope their range of sauces won't rub the Dragons up the wrong way, a London-based graduate hopes her automatic cooling device will chill any hot-tempered Dragons, and a Welsh entrepreneur plans to shift into high gear as he pitches his innovative bike storage solution.
