Many female founders appear to be in non-technical roles. Need more women in STEM fields moving into entrepreneurship roles as the technical lead.

A female CEO can hire as many women as she wants? A female founder in any role probably influences hiring tremendously.

Very true. However, having a woman in a lead technical role to provide mentorship and inspiration to female developers is very important for encouraging more women to become developers and stay in the industry.

For what it's worth, I'm fairly confident that it's illegal to discriminate on sex when making hiring decisions.

A female involved in hiring might mean the process is less discriminatory. Thus a female influencing hirings wouldn't necessarily be illegal, but potentially more legal.

I was talking about the issue with the comment above mine not collecting individual role information so you can't determine who does what, just their name, gender, and bio.
