It started with a $500,000 angel investment from billionaire Peter Thiel in 2004. Thiel joined Facebook's board of directors the next year, a position of influence and responsibility he held until 2022.
Investor interest skyrocketed after that. VC firm Accel Partners led a $12.7 million funding round in the spring of 2005, followed by a $27.5 million cash infusion from four firms in 2006. This Series B round locked down a 9.7% ownership stake in the company, valued at $468 million.
Several more VC investments followed in 2007 and 2008, including a $240 million commitment from Microsoft (MSFT -0.43%). This round valued Facebook at $15 billion, and Microsoft reportedly attempted to buy the whole company at that price. But Zuckerberg turned down that proposal and raised another $2 billion from VC firms Elevation Partners, Digital Sky Technologies, Triplepoint Capital, and others.
Facebook filed for an IPO after amassing more than 500 shareholders. The stock was worth almost $82 billion on the first market day. Some pre-IPO investors held on for the long haul, while others cashed in their winning stubs. Microsoft, for example, sold 20% of its Facebook shares shortly after the IPO, pocketing $249 million in total -- a $9 million profit from the original $240 million investment.
With a market cap of more than $740 billion in the summer of 2023, it's safe to say that Facebook's VC investors enjoyed healthy returns on their investments. Meta turned out to be the game-changing moonshot opportunity every VC investor dreams of.
