The story of Eduardo Saverin represents one of the most emblematic cases in the startup world: the transition from co-founder to spectator excluded from business decisions. In 2004, Saverin joined Facebook as Chief Financial Officer, investing capital, time, and most importantly, his trust in Mark Zuckerberg’s project. However, the path that followed would completely transform his position within the company.

The Initial Investment and Share Control

When Eduardo Saverin pooled his financial resources to support Facebook in its early days, his commitment was total. His 1,388,334 shares gave him 34.4% of the company—a significant stake that positioned him as a controlling shareholder. Alongside Zuckerberg and the other founders, Saverin was an integral part of the vision of what would become one of the most influential platforms on the planet. His financial expertise was considered essential for the organized growth of the company.

The Silent Dilution: From 34.4% to 0.03%

What happened in the following months remains one of the most controversial moments in Facebook’s corporate history. New funding rounds were structured in such a way as to significantly dilute Saverin’s position—a maneuver he did not authorize. His stake dropped from 34.4% to a tiny 0.03%, an orchestrated reduction without his informed consent. When the documents were handed to him, Eduardo Saverin faced a reversed reality: his role as co-founder had been effectively erased, while Mark Zuckerberg had consolidated absolute control of the company.

Legal Consequences and the Subsequent Conflict

Saverin did not remain passive in the face of what he considered a betrayal. He took legal action against Zuckerberg and Facebook, claiming his rights and challenging the legitimacy of the dilution. The legal conflict that ensued lasted years, culminating in a settlement agreement—though with terms much less favorable than what he could have obtained by maintaining his initial stake. Despite the subsequent formal reconciliation, Eduardo Saverin’s story remains emblematic of the risks founders face when they lose control of their creations.
