Haha, of course. "We're awake at night" would not be the point of the company, just an aspect of the culture. It'd probably have to be adjacent to other "night" industries though, or something with a good tolerance for asynchronousness, or have clients in appropriate timezones.
The original motto of the Pinkerton Detective Agency was "We Never Sleep".
They should be forced by law to accommodate that, then, so that there is no advantage in not doing it. Like they can't use child labor anymore.
