After leaving university, Chachchon declined an offer to join Goldman Sachs and instead chose to work for the family. According to a Thai biographer: "The Ratanarak's empire remains a giant with a bright future, with Chachchon Ratanarak the third generation leader in line to continue and to extend this solid family business's tradition of prosperity."Chachchon was invited to serve as a judge for the Bangkok Business Challenge, Asia's longest-running global student startup competition, hosted by Sasin School of Management since 2002. The competition features judges who are leading entrepreneurs and investors from the region, and Chachchon was the youngest judge on the panel.
The Ratanaraks are known to be very private; Forbes call them “a very secretive clan”, and Chachchon has been described as “influential while staying below the radar”. Despite their ownership in a variety of publicly listed companies, the Ratanaraks value privacy over publicity and rarely make an appearance. Even in the digital age when information is widely available, an Internet search on Chachchon would reveal very little information, all of which is in a professional capacity. He never appears in the society section of any media.
Chachchon has been a director of Siam City Cement from 2006 to 2019, during which the company shifted from being a leading domestic player to a regional player by expanding into fast-growing markets of Bangladesh, Cambodia, Sri Lanka and Vietnam.
Building on their existing substantial holdings, in August 2024, the Ratanarak Group strengthened its long-standing control over Siam City Cement by acquiring Jardine Cycle & Carriage Ltd.'s 25.24% shareholding for US$353.97 million. This move solidified the Ratanarak family's status as the founder and primary shareholders. After a subsequent tender offer to minority shareholders, the Group's total ownership of Siam City Cement increased to approximately 79%. Additionally, the Ratanarak family holds an interest of approximately 20% in Krungsri Bank, which has combined assets of ฿2.62 trillion.
Growing the family's existing businesses, Chachchon founded an asset management company Primavest in 2001 which at its height in 2007 had US$900 million in assets under management. Primavest was sold to Ayudhya Fund Management of Bank of Ayudhya in 2009. He founded Tonson Group in 2006 and Tonson Property in 2007 to conduct investment and property development businesses in Thailand and overseas.
According to Forbes, the Ratanarak family’s holdings in the group businesses in 2014 were estimated to be worth US$5.1 billion, based on publicly known assets and excludes private assets and property. In 2012, the Thai publication ‘Which Family is Richest’ reported the Ratanarak family as having holdings in excess of US$10 billion since 1998 when other assets are included.
