How Facebook was founded: Zuckerberg, Saverin, and the betrayal behind the billion

Executive overview

Mark Zuckerberg built Facebook out of a series of increasingly ambitious hacks at Harvard, driven less by business vision than by obsessive programming and a need for control. Eduardo Saverin funded the early operation and served as the business brain, but his refusal to go all-in on California sealed his fate.

The founding of Facebook is a story about what happens when a founder's commitment level diverges from a co-founder's — and who controls the cap table.

Zuckerberg before Facebook

• Hacked Harvard house photo directories at 1am to build Facemash, a "hot or not" site for classmates
• Turned down a $1–2M offer from Microsoft for his earlier project, Synapse
• Built CourseMatch so Harvard students could see which classes others had enrolled in
• Used crowdsourced student commentary to ace an art history exam he hadn't studied for
• Registered thefacebook.com on January 12, 2004; paid ~$85/month for servers

The Facebook launch

• Eduardo Saverin contributed $1,000 for the first servers and was named CFO
• Launch strategy: seed the Phoenix finals club first (social, well-connected, knew lots of girls), then Kirkland House list
• Mark stayed alone at his computer after launch while Eduardo went to celebrate
• Mark's self-assigned title: Founder, Master and Commander, and Enemy of the State

Sean Parker enters

• Parker arrived as a whirling, high-energy presence — part showman, part Silicon Valley veteran
• Zuckerberg treated Parker with "pure, idle worship" on first meeting; Eduardo was sidelined immediately
• Parker described Silicon Valley as an ongoing war, not a business environment
• Facebook's Baylor strategy: seed surrounding schools first, let Baylor students demand access themselves
• 85% of Stanford joined within 24 hours of a single newspaper article about the site

Eduardo vs. California

• Mark moved to Palo Alto for the summer; Parker crashed with him and became a de facto partner
• Eduardo stayed in New York, took an internship, and prepared to return to Harvard in the fall
• Parker's view: Silicon Valley required total commitment — Gates never graduated, Parker never went to college
• Eduardo froze the company bank account during a dispute, damaging trust irreparably
• Facebook accepted $500,000 from Peter Thiel, facilitated by Parker, triggering reincorporation as a C Corp

The dilution and the ambush

• Reincorporation required reissuing shares; new allocations tied to ongoing contribution
• Mark, Dustin, and Sean were in California working around the clock; Eduardo was not
• Documents issued up to 19 million, then 20 million authorized shares; additional tranches given to Mark, Dustin, and Sean
• Eduardo's stake dropped from ~30% to well below 10%, approaching near-zero with full issuance
• Eduardo flew to California expecting a business meeting; was handed the dilution papers on arrival
• He refused to sign; was told he was no longer an employee, no longer a founder, and would be expunged from corporate history
• He left without knowing the new president of Facebook was Sean Parker
