Dragon Steven Bartlett co-founded Social Chain, a social-media marketing agency.
Bartlett established the company in 2014 with Dominic McGregor. Social Chain focused on creating and distributing campaigns through online communities and social platforms, reflecting the growing importance of digital audiences in brand marketing.
The company grew from a Manchester-based start-up into an international agency group. Its work involved social-media strategy, branded content and online community building. Bartlett later became known as an entrepreneur, investor and podcast host before joining Dragon's Den in 2021.
Social Chain is sometimes confused with Bartlett's later investment activities or with companies he has advised. The question asks for the business he co-founded, not a company in which he subsequently invested.
