What is the name of the British Dragons' Den spin-off that lets viewers explore businesses online?

The British Dragons' Den spin-off that lets viewers explore businesses online is called Dragons' Den: Online.

The companion programme extended the main television format into an internet-focused experience. It gave audiences a way to find additional information about entrepreneurs and businesses beyond the edited broadcast episode, reflecting the growing importance of online participation in factual entertainment.

A television pitch is necessarily selective: many minutes of conversation can be reduced to a short segment, and the final broadcast may not show every detail of a negotiation. An online companion therefore offered extra context and encouraged viewers to engage with the businesses after transmission.

The title is easy to confuse with informal descriptions of Dragons' Den content on the web, such as clips, social-media pages or streaming episodes. Dragons' Den: Online is the specific British spin-off title. It is not the name of a later international adaptation or a generic label for watching the main programme online.
