Steven Bartlett co-founded Social Chain before joining the British television series Dragon's Den.
Social Chain is a social-media marketing agency founded by Bartlett and Dominic McGregor in 2014. The company grew from a digital-first business into an international agency group, giving Bartlett experience in online communities, branding and rapidly scaling companies.
Bartlett later brought that digital-business background to Dragon's Den when he joined the panel for series 20 in 2022. His route into the programme differed from that of older Dragons whose careers were rooted in retail, manufacturing, property or traditional finance.
Social Chain is sometimes confused with Bartlett's podcast brand, The Diary of a CEO. The podcast became another major part of his public profile, but Social Chain is the company he co-founded and the business named in this question.
