W olfgang Reimann is a German billionaire heir and one of four siblings who own the vast majority of JAB Holding Company, a massive privately held investment firm. The family's fortune originated with the 19th-century German chemical company Benckiser, which their ancestor acquired. In the 20th century, the company grew into a major consumer goods firm, which later merged to become Reckitt Benckiser. The Reimann family has since sold their stake in Reckitt Benckiser and transformed JAB into a global consumer brand empire.

Under the leadership of a team of professional managers, JAB has executed a multi-billion dollar acquisition strategy, focusing primarily on the coffee and food sectors. The firm has built a global coffee powerhouse by acquiring brands like Keurig Dr Pepper, Jacobs Douwe Egberts, and Peet's Coffee & Tea. It also owns Panera Bread, Krispy Kreme, and a controlling stake in the beauty company Coty. Wolfgang and his siblings are not involved in the day-to-day operations of JAB but are the ultimate owners of the vast conglomerate. The family has also been public about confronting and funding research into their ancestors' strong support of the Nazi party.
