Which Dragons' Den investor founded the digital-marketing company Social Chain?

Steven Bartlett co-founded the digital-marketing company Social Chain.

Social Chain was established by Bartlett and Dominic McGregor as a social-media marketing business. It built campaigns and online communities for brands, operating in a field shaped by viral content, influencer culture and platform-based communication.

Bartlett’s work at Social Chain is central to his public profile and explains why he brought digital-marketing expertise to Dragons' Den. He later became known as an entrepreneur, author and podcast host as well as a television investor.

The answer is sometimes confused with other dragons’ companies because the programme features businesses from many sectors. Touker Suleyman is associated with fashion and manufacturing, while Peter Jones has interests across technology and consumer businesses. Social Chain specifically belongs to Bartlett’s entrepreneurial career.
