In Dragons' Den, the rejected child-friendly ride-on suitcase created by Rob Law was Trunki.
Trunki is a lightweight suitcase designed so children can sit on it and ride while travelling. Rob Law presented the product on Dragons' Den, but the investors did not make a deal. The rejection became part of the product's public story because the business later achieved substantial commercial success.
The pitch is sometimes remembered as a general toy or as a ride-on vehicle, but Trunki is specifically a ride-on travel suitcase. Its design addresses a practical problem for families: keeping children engaged while moving through airports and other transport hubs.
The product was developed by Law through his company Magmatic. Its later success is often used to illustrate that a Dragons' Den rejection is not a reliable prediction of a product's future. A failed television pitch can still be followed by strong sales, licensing and international distribution.
