Trunki is the children's ride-on suitcase that was rejected on Dragon's Den before becoming a successful product.
Rob Law designed Trunki as a colourful, durable suitcase that children could sit on and ride while travelling. He pitched the product on the programme in 2006, seeking investment to help develop and market the idea. The dragons did not make an investment offer.
Trunki subsequently became a widely recognised travel product and won design awards. Its story is frequently cited as an example of the limits of television investment decisions: a pitch can be rejected on the day while the underlying product still finds a substantial market.
The product is sometimes confused with Brompton, which is a folding bicycle pitched by Andrew Ritchie. Trunki is specifically a child-focused suitcase, and the name refers to the product brand rather than the entrepreneur who created it.
