Those companies do exist. I can confirm specifically that at least when I had an offer from Supabase they paid everyone, internationally, regardless of location, the same pay bands. Being USA based it was one of the reasons that I turned down the offer because I was able to get a much higher salary elsewhere but it would have been extremely competitive had I taken the role and moved to some place like Vietnam. I wish I could have taken the Supabase role because it was definitely my top pick otherwise. One look at the output and caliber of people they hire also indicates that they have little issue finding talent. FWIW this was a couple of years ago and I have no idea whether they are still doing this equal pay band thing or not. But they were doing it for awhile at least
