QSIAbout & heritage

Five decades in resources.
Three generations of enterprise.

An Indonesian business founded in 1972, held through Hong Kong since 2015, and connected across five jurisdictions.

An Indonesian foundation.
A regional group.

The late Yong Kim founded and chaired PT Emas Goldenbell, the group’s first Indonesian operating company. His son, Isaac C. Kim, founded and chairs QSI Holdings.

PT Quantum Sungam International has since replaced PT Emas Goldenbell. In 2026, Yong Kim’s grandson, David Kimiyanto, founded AKN in Jakarta, extending the family’s commercial experience into food, consumer and industrial trading.

Quantum Sungam International Holdings Limited was incorporated in Hong Kong on 3 February 2015, bringing the international companies under one holding structure.
