The time is ripe as Facebook announces a massive $5 billion USD IPO. There was little surprise as to if but rather when the most revolutionary start-up of our generation would make the leap into the public domain. The S-1 filing will as you imagine make many people extremely wealthy with founder Mark Zuckerberg leading the charge with his 28.2% stake, which based on a suggested $100 billion USD valuation by many accounts puts Zuckerberg’s wealth at over $28 billion. Other groups and personalities involved with large stakes include early 2005 investors Accel and partner Jim Breyer (11.4%), co-founder Dustin Moskovitz (7.6%), DST (5.4%) and Facebook’s first investor, Peter Thiel (2.5%). The 200-some page S-1 can be seen here. A point worth noting is that 12% of Facebook’s current revenues revolve around the juggernaut online gaming platform Zynga and much of their immediate business hinges on that relationship.
