Which Dragon's Den investor founded the Phones 4u mobile-phone retail chain?

John Caudwell founded the Phones 4u mobile-phone retail chain.

Caudwell built his fortune in the mobile-telecommunications market and founded Phones 4u, which became a major United Kingdom retailer of mobile phones and contracts. The business expanded through shops and partnerships with network operators during the rapid growth of mobile-phone ownership.

He later appeared as an investor on the British version of Dragon's Den. His commercial experience made telecommunications, retail scale and customer acquisition especially relevant areas when assessing entrepreneurs.

Phones 4u is not the same company as Carphone Warehouse, another well-known British mobile retailer. The two names are often mixed up because they operated in the same market, but Caudwell is specifically associated with Phones 4u. He also became known for substantial charitable giving through the Caudwell Children charity.
