James Watt and Martin Dickie founded the brewery BrewDog.
The Scottish craft brewery was established in 2007 by Watt and Dickie. The company became known for aggressively marketed beers, including Punk IPA, and for helping popularise modern craft-beer culture in the United Kingdom. Its brand name combines the word “brew” with “dog,” producing the single name BrewDog.
Watt and Dickie appeared on Dragon's Den while seeking investment for their growing brewing business. The appearance is often remembered because the entrepreneurs later continued expanding without relying on a deal from the television panel. Their story illustrates that a pitch's television outcome does not necessarily determine the long-term trajectory of a company.
BrewDog is sometimes mistaken for the name of one of its beers, but BrewDog is the brewery and wider business. Punk IPA is a product associated with the company, not the company name itself. The founders are James Watt and Martin Dickie, rather than the investors who questioned them in the den.
