What was the title of the 2004 BBC pilot that led to the UK series Dragon's Den?

The title of the 2004 BBC pilot that led to the UK series Dragon's Den was Dragons' Den.

The pilot preceded the regular British programme, which began broadcasting in 2005. It tested the central idea of entrepreneurs presenting business proposals to a panel of investors who could offer money, expertise and contacts in exchange for an ownership stake.

The title is often written in two forms in discussions of the programme. The established British series title is “Dragon's Den,” while the pilot and some international branding use “Dragons' Den.” This punctuation difference can cause confusion, but it does not refer to a different investment concept. The format itself originated in Japan and was later adapted for broadcasters in multiple countries.
