Kedah-born Dato’ Seri Chew founded Keat Radio & Electrical Co. in 1965, a sole proprietor business, which was a retailer for radios and electrical appliances in Penang. More than a decade later, it expanded and was renamed ‘Pensonic’ – coined from two different words: "PEN" for the Penang and "SONIC" for sound, due to the company’s humble beginnings in the radio business. Their many award wins include the ISO 9001-2000 accreditation in 2002, the National Creativity & Innovation Award in 2004 by the Malaysia Design Technology Centre, and the Malaysia Good Design Mark by the Malaysia Design Council. Under his tutelage, this local brand now exports their products to East Asia, West Asia and the Middle-East.
