Levi Roots introduced Reggae Reggae Sauce to the Dragons' Den audience.
Roots, the stage name of Jamaican-British musician Keith Valentine Graham, appeared on the programme as an entrepreneur seeking investment for his Caribbean-style sauce. His pitch helped turn the sauce and its distinctive branding into one of the best-known businesses associated with the British series.
The product grew from Roots's musical and culinary identity. Reggae music, Jamaican food and a memorable brand presentation were central to how the business was presented to viewers. The Dragons' Den appearance became an important part of the company’s public story and helped bring the product to a much wider audience.
Reggae Reggae Sauce is a brand, while Levi Roots is the entrepreneur behind the pitch. They should not be treated as interchangeable answers: the question asks for the person who presented the business.
