I was on 143k usd before I left London and now work remotely for about 188k usd for a UK company. This was was with stock options as well.
As a salaried employee, that would be exceptionally high in almost any field. Obviously some such jobs exist, but unless you're a very senior figure in a relatively well-paid industry, you're an outlier at that compensation level.
I don't doubt you, but I suspect your startup was relatively well-funded and generous with its team. I know people who have earned that kind of money as well, but it's well outside the central part of the curve, even in tech and in London, for someone on salary. For independents with a good track record, sure, it's less unusual.
I'm still contacted by recruiters for salaries around that so the jobs exists.
All anecdotal but it does mean it's possible.
