In the British TV show Dragon's Den, which investor founded the YO! restaurant brand?

In the British TV show Dragon's Den, Simon Woodroffe founded the YO! restaurant brand.

Woodroffe launched YO! Sushi in London in 1997, introducing a conveyor-belt dining concept that allowed customers to select dishes as they passed by. The business helped make sushi more approachable to a wider British audience and grew into the broader YO! brand. His entrepreneurial career began in entertainment and hospitality before he moved into restaurant development.

Woodroffe was one of the original investors, or dragons, when the British version of Dragon's Den began. His experience was especially associated with branding, customer experience and creating distinctive formats rather than simply copying established restaurant models.

The company is often called YO! Sushi when discussing its early history, while YO! became the wider brand name. This is different from saying that Woodroffe founded every business later operating under the YO! name; the key founding venture was the sushi restaurant concept he launched in 1997.
