The co-founder of Facebook is Eduardo Saverin. He was a Harvard undergraduate when he met Mark Zuckerberg, a sophomore, in 2003. Saverin was impressed by Zuckerberg's programming skills and his vision for a social networking website for Harvard students. He agreed to invest $1,000 in Zuckerberg's project, which was initially called TheFacebook.
Saverin played a key role in the early development of Facebook. He helped Zuckerberg to launch the website on Harvard's campus in February 2004, and he also helped to secure funding from other investors. However, the relationship between Saverin and Zuckerberg soured in 2005, and Saverin was ultimately forced out of the company.
Despite his departure from Facebook, Saverin remains a billionaire. He still owns a small stake in the company, and he has also invested in a number of other successful startups. In 2016, he co-founded the venture capital firm B Capital Group.
Saverin's story is a complex one. He is both praised and criticized for his role in the founding of Facebook. However, there is no doubt that he played a key role in the company's early success.
