There are certain unicorns; I've worked for one. There are maybe unicorns; I've worked for a few.
Then there are non-unicorns. These may even start as maybe unicorns. But as soon as you know it's never going to be a unicorn, you can leave. Or stay, prospects depending. If you know it's never going to be a unicorn before you even join, you can think of it as glorified contracting. Done that too. Maybe lean on compensation rather than options because a whole lot of nothing is, tap-tap-tap, nothing.
