In many cases for a start-up that is freaking impossible. I've forked for giant companies and 9/10 tech resumes are male. Attempting to wait for two highly qualified women given our current hiring pool would take far too long, or force stretching what you mean by qualified (accepting alternative qualifications, etc.). Companies shouldn't make hiring choices based on gender. That is wrong, and likely illegal. Use statistical sampling to ensure the process isn't biased given the applicant pool, but otherwise hire the best, and look beyond skin tone and sex organs for diversity.
