The Giant Mafia
There is an old Chinese saying "Things of a kind come together. People of a mind fall into the same group.". In the wave of Web 2.0, there are many emerging IT giants coming out the world. And many of them are founded by a group of people who previously worked together at the same company such as PayPal and Facebook. This is called giant mafia. Let's see what people from the big IT giant have done after leaving the original company.
The PayPal mafia
Peter Thiel, co-founder and CEO of PayPal before sold to eBay. He is the founder of Founders Fund, a venture capital; and he also co-founded Palantir.
Elon Musk, co-founder of Paypal. And now he is the CEO and CTO of SpaceX, CEO and chief product architect of Tesla Motors, and chairman of SolarCity.
Reid Hoffman, a member of the board of directors during the founding of PayPal. He is the co-founder of LinkedIn, a business-oriented social network used primarily for professional networking.
David Sacks, chief executive officer and founder of Yammer, is a freemium enterprise social networking service that was launched in 2008 and sold to Microsoft in 2012.
The Facebook mafia
Adam D'Angelo and Charles Cheever. D'Angelo began working at Facebook the summer after his sophomore year at California Institute of Technology and eventually became the company's chief technology officer. Cheever was Facebook's software engineering manager for three years, until he and D'Angelo left to found Q&A website Quora in April 2009.
Dave Morin, is one of the men responsible for the Facebook Connect development. Since leaving Facebook in February 2010, he co-founded Path, the buzzy social network that declined a $100 million buyout offer from Google less than a year after it was launched.
Sean Parker, first disrupted the business world—and caught the ire of the music industry—in 1999 when he launched Napster. After founding online address book company Plaxo in 2001, he joined Facebook as its inaugural president in 2004. Since leaving the company under questionable circumstances, he formed Founders Fund with investor and former PayPal executive Peter Thiel.
Dustin Moskovitz was Zuckerberg's Harvard roommate and is the youngest person on Forbes's list of billionaires (he is eight days younger than his former boss). In November 2009, the Facebook co-founder left the company to co-found Asana, a workplace productivity start-up, with former Facebook engineer manager Justin Rosenstein.
Jeff Hammerbacher, used Hadoop for building analytic applications involving massive volumes of user data at Facebook. Later he co-founded Cloudera, a company provides Apache Hadoop-based software, support and services, and training to business customers.
