Which company did Steven Bartlett co-found before joining Dragon's Den?

Steven Bartlett co-founded Social Chain before joining Dragon's Den.

Social Chain is a social-media marketing and advertising company founded by Bartlett and Dominic McGregor. The pair started the business in 2014, building on their experience creating online communities and campaigns for brands. Its work helped Bartlett become known as a prominent young entrepreneur before his television appointment.

Bartlett joined Dragon's Den in 2021 as the programme's youngest-ever dragon. His experience in digital marketing made him particularly associated with pitches involving online audiences, social platforms and direct-to-consumer growth, although each investment decision still depended on the individual business.

Social Chain is sometimes confused with Red Letter Days, the experience-gift company founded by former dragon Rachel Elnaugh, or with unrelated online retailers. The names refer to separate businesses and different entrepreneurs. Bartlett later became widely known for The Diary of a CEO podcast as well as his business career.
