Which entrepreneur became a Dragons' Den investor in 2021 after co-founding Social Chain?

Steven Bartlett became a Dragons' Den investor in 2021 after co-founding Social Chain.

Bartlett is a British entrepreneur, author, podcaster, and investor. He co-founded Social Chain, a social-media marketing agency, with Dominic McGregor, and later became known for The Diary of a CEO podcast and related media work.

He joined Dragons' Den as a dragon in the nineteenth series, broadcast in 2021. His arrival added a younger investor with a background in digital communities, online marketing, and technology-led businesses.

Bartlett's role is sometimes confused with the earlier arrival of Touker Suleyman or the later-established presence of other investors. The identifying combination is precise: Social Chain co-founder, The Diary of a CEO creator, and 2021 Dragons' Den appointment.
