Then why stay? Why waste quality of life for a startup lottery ticket that data has repeatedly shown will most likely fail? Being a non-profitable early stage startup is no excuse to run the place like a slave ship.
I find it interesting that everyone always assumes that working more hours means less quality of life. I thoroughly enjoy my job, so spending more time doing it does not detract from anything.
