Rob Law pitched the children's ride-on travel case Trunki on Dragons' Den.
Law developed Trunki as a colourful, lightweight case that children could sit on and pull or ride through airports. He appeared on Dragons' Den in 2006, where the dragons did not make an investment deal. Despite that rejection, the product went on to become a successful international travel accessory.
The Trunki story is often cited as an example of a business that succeeded without Dragons' Den funding. Law retained control of the company and continued developing the product range under the Magmatic brand.
Trunki is sometimes mistaken for a conventional suitcase or for the Tangle Teezer, another well-known product associated with the programme. Trunki is specifically the ride-on children's travel case created by Rob Law.
