anecdata - in Berkeley CA, in the late 2010s, two individuals showed up to be in the fast-paced AD scene. One was from a former Soviet Union country, who spoke English pretty well .. and the other a woman from Columbia .. to say that both of these two were "aggressive" is an understatement. He spoke English, she was in charge of "security" .. after a very few meetups, they both formed a company for "Ad tech for Hospitals" .. it was "heavy security" they said, and therefore did not discuss any details in public. They very obviously would do "aggressive" actions to get into the business, defeat competitors, and satisfy ..clients? Who were they satisfying with the cultural norms, constantly aggressive stance, move fast and break things approach? Every single person involved had the motivation of Big Money, Now.
