Mark Zuckerberg founded Facebook while studying at Harvard in 2004, moved the young company to Palo Alto and retained a large founder stake as Facebook grew into the public company now called Meta. ^[1]^[4]

Building Facebook from a college project

Meta identifies Zuckerberg as the founder of Facebook in 2004 and says he studied computer science at Harvard before moving the company to Palo Alto. A contemporaneous Harvard Crimson account reported that co-founder Eduardo Saverin supplied the first $1,000 of startup money to keep the site running, giving the young company a modest co-founder-funded starting point rather than an inherited operating business. ^[1]^[2]

Facebook later financed its expansion with outside investors. In 2006 the company announced a $25 million round led by Greylock Partners, with Meritech Capital Partners and existing investors Accel Partners and Peter Thiel participating, showing how quickly the financing base broadened as the network grew beyond its original college audience. ^[3]

Founder control through the public-company era

Facebook went public in 2012, converting Zuckerberg's founder ownership into a large public-company fortune while he remained chief executive. The company later changed its name to Meta, but Zuckerberg's long-running founder, chairman and chief-executive roles kept the same business at the center of both his career and wealth. ^[4]^[1]

The financing history also explains why company growth and personal wealth are related but not identical. Outside capital diluted early ownership while funding expansion, yet Zuckerberg retained enough founder equity and control for the public-market value of Meta to remain the dominant driver of his fortune rather than salary or the company's gross revenue. ^[3]^[1]^[4]
