Why there is a PayPal Mafia but no Google Mafia
Palantir has a great mafia: Addepar, Affirm, Anduril, Blend, SourceGraph, Handshake, Ironclad, Mosaic, Bold, Peregrine, Certain Lending, Table.ai, and a bunch of others!
You know who I think had perhaps the strongest “mafia” of the last hundred years? Drexel Burnham Lambert
This seems quite a good hypothesis. I am not able to find counter-examples as per my awareness.
