The regular Platinum is the card I’ve had open the longest with AmEx - started with a Gold charge card, did the upgrade to Platinum and kept it ever since (this was some 15 years ago). So I think I kept it partially for nostalgia and also because I like the credits (airline, uber, streaming). I get the MS Platinum for free so I added that on to double up on the aforementioned credits.

I am honestly not sure what is included in the “introduction” - does MS tell AmEx about my assets, etc? I don’t know - he just intimated that they have a relationship with AmEx and can refer/introduce folks to Centurion. He confirmed that they made the introduction a few days later and that whether or not anything came of it was now out of their hands and with AmEx. My frame of reference is a bit skewed because of geography (i.e. lots of UHNW folks in my vicinity), but my banker has been through a couple of liquidity events with me and I personally believe the relationship is strong enough to merit a “please take a serious look at this guy” intro Whether the MS intro factored into the invite itself - your guess is as good as mine. I am of the belief that the intro might’ve tipped the scales in my favour, but that invites are still largely based on types of spend - so if my spend had been 200k of AdWords and office supplies yearly, the MS intro may not help much.
