There is/was a US firm with a number of Starfighters that very rich people could pay to fly - they also negotiated access to US military ranges in order to be able to let them fly supersonic. Indeed, their presence as "enemies" at the various international airforce meets, often brought comments that the fastest/most capable fighters taking part were the private ones! eta - Seems they have refocused their business to government-contract R&D/Space/sattelite-related work recently. Maybe the millionaires plaything market isn't paying so well for them these days?

Also a firm in South Africa that took over the SA airforce/ex-RAF Buccaneers and operate them privately.
Dave Gilmour of Pink Floyd also operated his personal aircraft collection on a commercial basis for some years, which included a couple of reasonably up to date jets - although after he sold it a while back, its new owners moved its focus to supplying aircraft to film/TV work.
There are quite a few places where you can fly in older jets, Starfighters, L-39s, and similar, but I was thinking along more current lines.
Until relatively recently you could pay 15 grand for a supersonic blast in a MiG-29, but they're off the menu now, for obvious reasons.
