Which British Dragon's Den investor is known for founding Phones 4u?

John Caudwell is the British Dragon's Den investor known for founding Phones 4u.

Caudwell co-founded the mobile-phone retailer with his brother Brian Caudwell in the 1980s. The business became one of the United Kingdom's best-known mobile-phone chains during the rapid expansion of the consumer mobile market.

He appeared as a Dragon in the early British series, bringing experience from telecommunications retail and large-scale entrepreneurship to the panel. His business background differs from that of investors whose reputations were built mainly in fashion, property or technology.

Phones 4u later became the subject of major commercial changes and ceased trading as a retail chain in 2014. That later event does not alter Caudwell's connection to its founding. The company name is written with the numeral 4, a branding choice that can cause it to be confused with unrelated phone retailers.
