Levi Roots pitched the Reggae Reggae Sauce business on Dragons' Den.
Levi Roots appeared on the BBC programme as the entrepreneur behind a Caribbean-inspired sauce brand. His pitch helped turn a product associated with his musical and culinary identity into a widely recognized commercial business. The brand's name and presentation made the pitch one of the programme's most memorable.
The entrepreneur's birth name is Keith Valentine Graham, but he is publicly known as Levi Roots. That distinction matters because the canonical answer to the television question is his stage and business name, not his birth name.
The Reggae Reggae Sauce pitch is also remembered because Peter Jones and Richard Farleigh invested. The question asks for the entrepreneur, however, rather than the investors or the company. Levi Roots is therefore the single intended answer.
