Which Dragon became the youngest investor ever to join the British series Dragons' Den?

Steven Bartlett became the youngest investor ever to join the British series Dragons' Den.

Bartlett joined the panel in 2022, aged 29. His appointment brought a notably younger technology and social-media entrepreneur into a programme whose earlier investors were generally older and had built businesses over longer careers.

He co-founded Social Chain, a social-media marketing agency, with Dominic McGregor in 2013. The company grew from a digital-media start-up into an international business, giving Bartlett experience in branding, online communities and modern marketing.

Bartlett's age is often confused with the ages of other Dragons when they first appeared. The important comparison is the age at appointment, not the age at which an investor founded a company or made a first deal. His arrival also reflected the programme's growing interest in digital businesses and younger founders.
