Which British entrepreneur pitched Reggae Reggae Sauce to Dragons' Den investors in 2007?

Keith Valentine Graham pitched Reggae Reggae Sauce to Dragons' Den investors in 2007; he is better known by the name Levi Roots.

Roots used his stage name for his public career, but the businessperson behind the pitch was born Keith Valentine Graham. His presentation connected the sauce with Jamaican food and reggae culture, helping the product stand out in a crowded food market.

The pitch led to investment discussions with Peter Jones and Richard Farleigh and became a landmark moment in the British programme's history. Roots went on to build a broader food brand and became a prominent entrepreneur, musician and television personality.

This question uses the legal birth name because it tests a detail that is often missed when the story is retold. Levi Roots is not a separate investor or company: it is Graham's adopted professional name. Reggae Reggae Sauce is the product he presented, while the entrepreneur's birth name is Keith Valentine Graham.
