Rob Law created Trunki, the reusable children's ride-on suitcase featured on Dragon's Den.
Law designed the product as a child-sized, ride-on piece of luggage intended to make travelling more engaging for children. Trunki was developed by Law's company Magmatic and launched in the United Kingdom in the mid-2000s.
Law pitched the idea on Dragon's Den in 2006. The dragons did not invest, but the product went on to become commercially successful and won design recognition. Its bright colours, horn-like handles and ability to be pulled or ridden helped distinguish it from ordinary children's luggage.
The Trunki story is often cited as an example of a business succeeding after receiving no deal in the Den. A televised rejection is not the same as a negative verdict on a product's eventual market performance.
