What was the name of the Dragon's Den spin-off series in which investors revisited businesses after their pitches?

The Dragon's Den spin-off series was called Dragons' Den: What Happened Next?

The spin-off followed entrepreneurs and businesses after their appearances in the main programme. That format allowed viewers to see whether deals completed, how companies developed and what happened when a pitch moved beyond the television studio. It added a retrospective business-story element rather than simply presenting new entrepreneurs seeking investment.

The title is easy to confuse with informal descriptions such as “after the deal” or “inside the Den,” but those are not the official programme name. The question concerns the British television spin-off connected to Dragon's Den, not a general episode segment or an international adaptation.
