The story

Founded by Eka Tjipta Widjaja in 1962.1

In its early days, Sinar Mas was first started as a small grocery shop in 1938 in Makassar, Dutch East Indies by Eka Tjipta Widjaja. After the end of the Indonesian national revolution, Eka started to expand his business into copra, palm oil, and paper production. After the failure of his copra business, Eka later established CV Sinar Mas in Surabaya and established a cooking oil factory along with a paper mill in the city.

In 2010, Smartfren was founded as a result of a merger with a telecommunications provider, Fren.

Since 2003, Sinar Mas no longer calls itself the Sinar Mas Group because after restructuring Sinar Mas no longer has a holding company, but rather a President's office that facilitates/assist in implementing its business pillars.
