Peter Jones was the investor who appeared in every series of the British Dragons' Den through 2024.
Jones is a British entrepreneur and businessman whose interests have included telecommunications, media, leisure and technology. He joined the original panel when the programme began in 2005 and became its longest-serving continuous dragon.
The panel has changed repeatedly over the show’s history. Investors such as Duncan Bannatyne, Theo Paphitis, Deborah Meaden and others have appeared in different periods, while guest dragons have also joined individual series. Jones’s continuous presence distinguishes him from dragons whose tenures were shorter or intermittent.
The question specifies the period through 2024 because television casts can change after a publication date. It also concerns the British version, not international adaptations, which have separate investor panels and different broadcast histories.
