That's revenue though, not profit. Subtract office rent or home office expenses, laptops and other hardware, server running costs, overhead like this hiring process / HR / legal / sales / ..., employee-specific overhead costs like health insurance (if I get $50k/y then a few % is subtracted for health insurance, but half of that % I never see and the employer has to add on top of the agreed-upon salary)... and maybe you want to keep a buffer for unforeseen events (having to do without your Ukrainian employees for a while, sick leave, new covid wave where anyone with a child is at like 50% capacity, etc.). I'm no businessman but this is just what I can think of that my employer has to take care of from a developer-level position myself. Even if in most countries the rate is less than half the USA's, without doing the actual math this sounds like quite a tight margin to be honest.
