Which Dragon's Den investor joined the BBC series in 2021 as a technology entrepreneur?

Steven Bartlett joined the BBC series Dragon's Den in 2021 as a technology entrepreneur.

Bartlett joined the panel for the nineteenth series, making him one of the programme’s younger investors. His business background came from digital media and technology rather than traditional retail, manufacturing or property investment.

He co-founded Social Chain, a social-media marketing agency, with Dominic McGregor in 2014. Bartlett later became widely known for hosting The Diary of a CEO podcast, which broadened his public profile beyond business investment.

The year 2021 identifies his appointment to Dragon's Den, not the founding of Social Chain. His arrival also followed a period in which the programme’s panel had changed several times, so series numbering and broadcast years are useful for distinguishing his debut.
