Daniel 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. His family's industrial legacy began in 1924 when his grandfather, Leon Feffer (a Ukrainian immigrant), established a paper trading firm.

Daniel and his siblings are the third generation to control the Group. Their fortune is rooted in the strategic vision of their father, Max Feffer, who pioneered the use of eucalyptus pulp to produce paper in Brazil, creating a massive, vertically integrated empire. Daniel Feffer is a highly educated executive, holding degrees in Law and Business Administration from prestigious Brazilian institutions, as well as attending courses at Columbia University and IMD in Switzerland, preparing him for the complex governance of the multi-billion dollar company.

Daniel Feffer's career has been spent in executive and governance roles within the Suzano Group. His strategic focus is on the long-term stewardship of the family's assets, ensuring the Group maintains its global leadership in the pulp and paper sector. The company's 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 and his siblings successfully professionalized the management, maintaining ownership control while entrusting business operations to a non-family professional team. This stability is the cornerstone of the family's wealth. Daniel's sister, Marina Feffer, is a prominent figure in philanthropy, having founded the Generation Pledge to encourage wealthy heirs to donate a portion of their inheritance, reflecting the family's commitment to social responsibility.

Daniel Feffer's social impact is massive and structural, stemming from Suzano's role as a major sustainable forestry and paper producer. The company's pioneering use of eucalyptus pulp revolutionized the industry, and its focus on biotechnology promotes environmental sustainability.

He is President of the philanthropic Council for Philanthropic Foundation ARYMAX and Vice-President of the EcoFuturo Institution. His sister's founding of the Generation Pledge is a major global initiative aimed at structural change in high-net-worth giving, reflecting the family's deep commitment to philanthropy and societal welfare.

Daniel 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 financial reward 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 high-stakes industrial mergers with a strong commitment to family governance and social responsibility.
