Soeryadjaya co-founded Astra in 1957, then a trading company, with his younger brother Tjia Kian Tie. The company grew to become Indonesia's largest automobile retailer and the country's biggest company by market value. The company, which also owns finance, plantation, auto parts manufacturing, automotive businesses, and heavy machinery and mining services, sells Honda motorcycles, BMW, Daihatsu, Peugeot, Citroën and Toyota vehicles throughout Indonesia. In March 2010, Astra overtook Telkom Indonesia to become Indonesia's most valuable company.

Soeryadjaya lost control of Astra in 1992, when he sold most of his family's shares to rescue Summa Bank, which was owned by his eldest son Edward Soeryadjaya,{{cite news |title=William Soeryadjaya, Revered Founder of Astra International, Dies Aged 87 |url=http://www.thejakartaglobe.com/archive/william-soeryadjaya-revered-founder-of-astra-international-dies-aged-87/ |work=Jakarta Globe |date=April 4, 2010 |accessdate=30 January 2014 |archive-date=February 3, 2014 |archive-url=https://web.archive.org/web/20140203184815/http://www.thejakartaglobe.com/archive/william-soeryadjaya-revered-founder-of-astra-international-dies-aged-87/ }} that had suffered from a credit crisis and finally collapsed. He personally guaranteed all Summa Bank depositors their money back, and all depositors received their money back with interest without using any bailout package from the government at the expense of his ownership in Astra.{{Citation needed|date=January 2014}}
