Who became the youngest-ever Dragons' Den investor when he joined the UK panel?

Steven Bartlett became the youngest-ever investor on the British Dragons' Den panel when he joined the show.

Bartlett is a British entrepreneur, author and podcaster best known for co-founding the social-media marketing company Social Chain. His career was built largely in the digital and technology sector, giving the panel a dragon whose experience came from online communities, branding and internet-scale growth.

He joined Dragons' Den for the nineteenth series in 2021. At 29, he was notably younger than the established investors, and the BBC described him as the youngest dragon in the programme's history at that point. His appointment reflected the growing importance of digital businesses and social-media-led brands in the entrepreneurs' pitches.

The distinction is about age at the time of joining, not the youngest person ever to appear as a contestant. It is also separate from the age of any guest dragon or replacement investor in later international versions of the franchise.
