In the British TV series Dragons' Den, Peter Jones is the founder of the telecommunications company Phones International.
Phones International was established by Jones as part of his early business career in mobile communications. The company operated in the mobile-phone sector, a field that helped build Jones's reputation as a technology and telecommunications entrepreneur before his television work made him widely known.
Jones became one of the original dragons when the British programme launched. His on-screen identity is associated with technology, consumer products, media and scalable businesses, although his investment interests extend across several industries.
This question concerns the company founder, not the company's general line of business. Phones International primarily concerned telecommunications and mobile phones, but the uniquely identifying answer is Peter Jones. That distinction avoids confusing the founder with other investors or with later companies in Jones's portfolio.
