Gstaad is 'exclusive'. It probably isn't so well known, but it has very expensive resorts and hotels, like https://www.thealpinagstaad.ch/ and its own private bank https://www.saanenbank.ch/ and the centre of the village has a lot of luxury shopping. It is definitely up there in terms of destinations for UHNW people. However I don't think it attracts quite such a percentage of "can afford to go but not ultra high net worth" people, which is much more true of Zermatt, Verbier, St Moritz etc.
