The top 10 tech mafia groups in the world
You’ve probably heard of the legendary PayPal Mafia, a group of founders and early employees at PayPal who all went on to start some of the most prominent companies in Silicon Valley.
🔆 Where the term comes from:
Fortune coined the term ‘tech mafia’ in 2007 when they released a piece on the PayPal Mafia along with a photo of some of the members dressed in swanky, gangster-looking attire.
Tech mafia refers to groups of former employees at tech startups, that then went on to found their own successful companies.
I recently wrote a piece for GoingVC on the top 10 tech mafia groups, sourced from the PIN (Power in Numbers) team.
