Personal, Business, Charles Schwab, Morgan Stanley and Goldman Sachs.
I have the impression that the Goldman card is for employees, but I do not know why I think that. In any event we have near zero information about it.
WRT Goldman Sachs, as I recall from researching out of curiosity some time ago, I believe the card is offered to customers with a private banking relationship and a minimum of $10 million in assets held at GS. Additionally, the card is available to GS employees as well, but without the $10 million asset requirement.
Of course, anyone putting $10 million to work at GS, in high cost investments, just to get a Amex Platinum card would have to be out of their minds, but that is a different thread...
