Which British Dragon's Den investor is the founder of Amstrad?

Alan Sugar is the founder of Amstrad.

Amstrad was founded by Alan Sugar in 1968, initially trading in consumer electronics and later becoming known for products including home computers, satellite television equipment and audio technology. Sugar's business success made him one of Britain's most recognisable entrepreneurs before he joined television investment programmes.

He served as a Dragon on Dragon's Den, but many viewers also know him as the host of The Apprentice in the United Kingdom. That television association can lead to confusion about which programme he appeared on. The question concerns his Dragon's Den investment role and his founding of Amstrad.

Amstrad is an abbreviation derived from Alan Michael Sugar Trading. The company became especially prominent during the home-computer era, when its machines competed in Britain's growing personal-computer market. Sugar later sold Amstrad to BSkyB in 2007.
