Peter Jones is the British entrepreneur and television investor known as the Dragon who founded Phones International Group.
Phones International Group was established by Jones as a telecommunications business. His experience in mobile phones and communications helped shape the commercial perspective he brought to Dragon's Den, where he became known for examining business models, ownership percentages and routes to scale.
The company name is easy to confuse with later telecommunications brands or with businesses in which Jones invested. Phones International Group identifies the venture he founded, whereas the programme features many separate companies seeking his investment.
Peter Jones is also associated with other business interests and television work, but the founding connection in this question is specifically Phones International Group. That makes the company a useful way to distinguish him from other Dragons with retail, leisure or property backgrounds.
