B ahari Karim is an Indonesian billionaire and one of the three brothers who own and run Musim Mas, one of the world's largest integrated palm oil companies. The business was established by their father, Anwar Karim, who began with a humble soap factory before expanding into palm oil. Bahari, along with his brothers Bachtiar and Burhan, inherited the business and have been instrumental in its massive growth.

Musim Mas has operations that span the entire palm oil value chain, from cultivating vast plantations to refining the oil, producing specialty fats and oleochemicals, and manufacturing consumer products. The company is a major global player, with a significant presence in both the upstream and downstream sectors of the industry. While his brother Bachtiar is the chairman and CEO, Bahari plays a key role within the family's leadership structure. The Karim brothers are known for their deep operational expertise and for maintaining an extremely low public profile, preferring to run their privately held empire out of the spotlight.
