>The reality is that tech companies led by women do better
Wow, what a sexist thing to say. Ignoring Marissa Mayer for the moment, are you claiming that women are inherently better at something than men? Isn't that a little like claiming that men are better than women at technical roles? That white people are better than black people at building civilization? Seriously, that is a nazi-esque belief you have there. I suggest you reconsider your stance before making claims about one group being better in any way than another.
