Rob Law pitched the suitcase brand Trunki on the British show Dragon's Den.
Law designed Trunki as ride-on luggage for children. The product was intended to make travelling easier and more entertaining by allowing a child to sit on and pull the case. Law presented the business on Dragon's Den, but the Dragons did not make an investment deal with him.
Trunki nevertheless became a notable example of a business that achieved commercial success after appearing on the programme without receiving backing in the studio. The product went on to be sold internationally and became associated with colourful, child-friendly travel design.
The story is often used to show that a rejection on Dragon's Den is not a definitive commercial verdict. A pitch may fail to secure investment because of valuation, manufacturing concerns, or negotiation terms while the underlying product still finds customers. Rob Law is the entrepreneur linked specifically with Trunki, not Tangle Teezer, the separate detangling-hairbrush business.
