The emergence of various entrepreneurial groups, notably the Monzo Mafia and the PayPal Mafia, highlights the impact of alumni networks in the tech industry. The Monzo Mafia, comprised of former employees from the digital bank Monzo, has reportedly founded startups that have collectively raised over $2 billion in funding. Meanwhile, discussions surrounding the PayPal Mafia suggest a need for rebranding, with some humorously proposing the name 'White House Mafia' due to their influence. Comparatively, the Coinbase Mafia is noted as having significant work ahead to match the legacy of the PayPal Mafia. Additionally, a playful rivalry has emerged, with references to the 'Memelord Mafia,' which claims to wield considerable influence over social media and meme culture, positioning itself as a powerful entity in the tech landscape.
