Which company did Peter Jones found before becoming a Dragon on the British programme Dragons' Den?

Peter Jones founded Phones International Group before becoming a Dragon on the British programme Dragons' Den.

Phones International Group was established by Jones in 1998 and operated in the mobile-communications sector. The business formed part of his wider entrepreneurial career before his television role made him a household name. His experience in telecommunications helped shape the commercial perspective he brought to the Dragons' Den panel.

Jones had already built and sold businesses before joining the BBC programme in 2005. His portfolio has included interests in technology, media, property and consumer brands. This breadth is one reason viewers often associate him with evaluating businesses beyond the industries in which he first made his name.

Carphone Warehouse is a plausible but incorrect answer because it is another well-known British mobile-phone company. It was not founded by Jones. The specific company connected to Jones's own early telecommunications career is Phones International Group.
