D avid Feffer is a Brazilian billionaire and the chairman of the board of Suzano, one of the world's largest pulp and paper producers. He is the grandson of the company's founder, Leon Feffer, who started the business in 1924, and the son of Max Feffer, who greatly expanded it. David represents the third generation of the family to lead the enterprise.

Under his leadership as CEO and now as chairman, Suzano has grown into a global powerhouse, particularly in the production of eucalyptus pulp, a key raw material for paper and tissue products. He was the architect of the company's transformative merger with its domestic rival, Fibria, in 2018. This massive deal created the undisputed global leader in hardwood pulp production. He and his three brothers, Daniel, Jorge, and Ruben, control the publicly traded company through their family holding company, Suzano Holding.
