I am a woman and I have worked at four different startups in finance. I have to say, women weren't treated differently to men insofar as civility seems orthogonal to success in finance.
But after ten years of ninety hour weeks, "special" weekend projects, perpetual release death marches, and striving to meet unrealistic deadlines, you know... I am really thinking of downshifting. Not for children, not for society's expectations, not because I can't make it in a man's world - but because I would really just like to take a long hot bath with a cigarette, a glass of wine, and some Chaucer, and then... leave and never come back to any of this rot.
So please don't tell me how you really feel about "women in startups" or whether there should be more of them or less of them or your pet theory about how two X chromosomes result in the inability to reason or to compete. I'm here to code and the rest is just not very interesting.
