Which Dragon joined the British Dragon's Den panel in 2021 after founding Social Chain?

Steven Bartlett joined the British Dragon's Den panel in 2021 after founding Social Chain.

Bartlett co-founded Social Chain, a social-media marketing agency, with Dominic McGregor in 2014. The company grew from work aimed at online communities and brands, making Bartlett one of the younger technology and media entrepreneurs to join the programme.

He became a Dragon in the nineteenth series of the BBC show, which aired in 2022. His investment interests often focus on digital businesses, consumer brands and technology-led companies.

Bartlett's appointment is sometimes dated to the broadcast year rather than the announcement and filming period. The panel change was announced in 2021, while the relevant series was broadcast in 2022.
