In Dragons' Den, which dragon co-founded the social-media company Social Chain?

Steven Bartlett co-founded the social-media marketing company Social Chain before joining Dragons' Den as an investor.

Bartlett established Social Chain in 2014 with Dominic McGregor. The company focused on social-media marketing and online communities, reflecting the growing importance of digital platforms to advertising and brand building during the 2010s.

Bartlett later became known for The Diary of a CEO podcast and for his role as a technology-focused investor. He joined the Dragons' Den panel in 2022, bringing a younger digital-business perspective to the programme.

Social Chain is distinct from Bartlett's podcast and from his later investment activities. The company was originally founded as a social-media agency, not as a television production business or a consumer brand.
