I know some people who worked on building bespoke software/automation systems for the homes of the ultra rich.
There are of course family office wealth management firms, know a few people there too. Basically if you have >$10bb (min threshold might be less, but their clients are in this range) you might just make your own wealth management firm where everyone is 100% focused on your stuff only.
A lot of the services only for the ultra rich are kind of boring though, boiling down to running large personnel teams for specialized tasks. Like chefs/catering, cleaning and groundskeeping, transportation.
