Rob Law founded the British company Trunki, whose ride-on children's suitcase became associated with Dragon's Den.
Law developed the product as a child-friendly alternative to conventional luggage. Trunki cases are designed so that children can sit on and ride them while travelling, giving the product a distinctive use beyond ordinary suitcase storage.
Law appeared on Dragon's Den in 2006 seeking investment, but the Dragons did not make an offer. The company nevertheless went on to grow commercially, an outcome often discussed when people compare television rejection with later business success.
Trunki is sometimes confused with a Dragons' Den investment because its television appearance was highly memorable. The founder's name is Rob Law, while the product and company are both commonly referred to as Trunki.
