It seems that if anything having a woman as a cofounder would be a positive thing. I am basing this off all the "women in tech" initiatives from big players in the industry.
Big players and startups are quite different cases..
> she thinks we're better off not listing her as a co-founder.
Why does she think this?
That's her opinion: "It's perceived that in general women are more emotional, so that may throw up red flags to some investors, since they may consider it a higher risk that the team could split up"
So what? It's also "perceived" that women are more scheming, which could be a thorough advantage in business.
Probably that's the main reason for some VCs to especially welcome female startup CEOs, lol. But we're talking not about CEO.
