Have women as your first few customers. Sell to Women initially. Only pitch to women VCs etc... When you get beyond a certain point hire men to deal with men you don't want to deal with.
First of all, MEN have the most money and power. You are literally telling me that the path to power is to limit myself to the dregs of society. Like that makes some kind of logical sense.
Second, the black community in the U.S. did this sort of thing. They had a thriving, well to do community in Greenwood, Oklahoma known as The Black Wall Street. The result: Whites burned it to the ground and then promptly began changing the laws in order to hamstring their ability to rebuild on the completely made up bullshit theory that their homes needed to meet a stricter fire code since it had burned to the ground. The ONLY reason it burned to the ground is because asshole whites set it on fucking fire.
So, no, this absolutely does not work. With a problem like this, you take the bull by the horns and address the root problem or it absolutely does NOT go away. You cannot tip toe around sexism, racism, etc. They are malignant forces that actively hunt down and target people. Politely avoiding them never, ever works.
You're basically describing affirmative action or quotas. They worked successfully in the Nordic countries to improve the gender ratios over there. The Navy did it with great success. Many companies do it including First Horizon that's near me which tries to stay half and half.
This can work but essentially you have to either make it law or convince the VC's to do it willingly. Those are big political problems that would take a lot of targeted work done right. If it can be done at all.
The problem with quotas is that it isn't that kind of problem.
It isn't predominantly that qualified women are applying and being turned away because of gender discrimination, it's that industry-wide the number of qualified women necessary for an even gender balance do not exist.
They went to school for teaching or medicine or real estate and the 17 year old girls deciding which college program to apply to are still doing the same thing.
