Rob Law pitched the ride-on children's suitcase Trunki on Dragon's Den.
Trunki is a wheeled suitcase designed for children, allowing them to sit on and pull or carry it while travelling. Law presented the product to the investors seeking funding, but the pitch did not produce an investment deal. The rejection did not prevent the product from becoming commercially successful.
The case is often used to illustrate that a television rejection is not the same as proof that a business will fail. Trunki went on to win design recognition and achieve international sales. Its bright colours and ride-on shape helped distinguish it from conventional children's luggage.
People sometimes remember the pitch as a successful Dragon's Den deal because the company later became prominent. The key distinction is that Rob Law appeared on the programme, but the dragons did not invest in Trunki.
