David Feffer is a Brazilian businessman and a controlling heir of the Suzano Group (now Suzano S.A., B3: SUZB3), a global leader in the pulp and paper industry, specializing in eucalyptus pulp. Born in 1956, his family's industrial legacy began in 1924 when his grandfather, Leon Feffer (a Ukrainian immigrant), established a paper trading firm.

David Feffer is the eldest son of Max Feffer, who pioneered the use of eucalyptus pulp to produce paper in Brazil. David received a comprehensive education, holding a law degree from Mackenzie University and a business administration degree from Fundação Getúlio Vargas, as well as attending courses at Columbia University and IMD in Switzerland. This prepared him for the complex governance of the multi-billion dollar company.

David Feffer assumed a leadership role in the Suzano Group, eventually presiding over the conglomerate since 2003. His strategic focus has been on ensuring the company maintains its global leadership through continuous innovation and strategic consolidation. The most significant milestone under the family's guidance was the $7.5 billion acquisition of Fibria Celulose in 2019, which created Suzano S.A., establishing it as the world's largest producer of eucalyptus pulp.

Feffer's role is primarily strategic and focused on governance, serving as an acting member of the LafargeHolcim International Consulting Council. His family professionalized management, maintaining ownership control while entrusting business operations to a professional team. His immense wealth is secured by the company's long-term stability and its dominance in the essential pulp and paper sector.

David Feffer's social impact is massive and structural, stemming from Suzano's role as a major sustainable forestry and paper producer. The company's commitment to eucalyptus pulp revolutionized the industry and promotes environmental responsibility in Brazil.

He acts as president of cultural and social institutions such as the Council for Philanthropic Foundation ARYMAX and supports cultural, environmental, and educational causes. His daughter's Generation Pledge is a global initiative aiming for structural change in philanthropic giving among wealthy heirs.

David Feffer maintains the professional, composed style of a top-tier Brazilian industrial executive. His attire is consistently formal and high-quality, favoring tailored suits. His aesthetic reflects the stability and institutional credibility of his multi-billion dollar industrial empire.

Residing in São Paulo, his luxury is the immense security and autonomy derived from his dominance in the global pulp and paper market. His life is defined by the disciplined stewardship of his family's legacy, balancing industrial mergers with a strong commitment to family governance and social responsibility.
