Unfortunately, while starting your own tech company might mitigate peer perception problems in the workplace, you instantly are dealing with a far, far greater problem - the perceptions of your customers and your financiers, be they banks, VCs, or friends and relatives.
In fact, you get second order effects, where VCs won't invest, even when they believe you're completely capable, because they know that customers will question the competency of women founders. Since they're in it to make money, they completely rationally discriminate.
But it's still discrimination.
The other thing is that women like to claim they're paid less than men which begs the question why would companies hire men if they could pay women less?
(1) "women like to claim"? Come on, the statistics are iron-clad. How about "women are paid less than men for the same job". Period. Now, sure you can have lots of arguments about *why*, but don't even try to pretend the stats aren't clear. What's next "scientists like to claim evolution is real"?
(2) Companies are made of people. And those people have the same tics (especially where things don't have a perfect metric to make comparison easy) as the rest of us.
(3) Also, people like to hire like. I'm a techie, and I enjoy geek culture. But none of the women I work with, all of whom are exceedingly competent, are geeks, especially enjoy geek culture, or love tech for its own sake. Nor do they need to in order to be exceptionally valuable programmers. However, I've seen them occasionally overlooked because they lack all the "tells" of geek prowess. Certainly, if I was hiring, I could easily pass them over for someone who "speaks my language".
So, no, I don't expect a revolution in hiring any time soon.
