Steven Bartlett co-founded Social Chain before his Dragon's Den appearance.
Social Chain was a social-media marketing agency founded by Bartlett and Dominic McGregor in 2014. It developed campaigns and online communities for brands, operating at the intersection of advertising, digital culture and influencer-led media.
Bartlett's experience at Social Chain helped establish his public profile as a technology and media entrepreneur. He later became known for The Diary of a CEO podcast before joining Dragon's Den in 2022.
The company name is easy to confuse with Bartlett's podcast or with businesses belonging to other Dragons. Hawes & Curtis is associated with Touker Suleyman, Crafter's Companion with Sara Davies, and Hamilton Bradshaw with James Caan. Social Chain specifically identifies Bartlett's co-founded agency.
