Rob Law pitched Trunki on Dragon's Den before it became commercially successful.
Trunki is a children's ride-on suitcase designed by British inventor Rob Law. Its moulded shell allows a child to sit on the case and move along on its wheels, making luggage more engaging and potentially easier to handle during family travel. The product also includes normal suitcase storage.
Law appeared on Dragon's Den seeking investment, but the televised pitch ended without the deal he wanted. Trunki nevertheless went on to become a well-known product sold in multiple markets. The story is one of the programme's clearest examples of a business continuing to grow after the entrepreneur leaves the Den without a Dragon.
The product name is sometimes confused with the generic phrase “ride-on suitcase.” Trunki is the specific brand created by Law. It is also different from a ride-on toy: its primary purpose is carrying travel items, with the ride-on design added to the case.
