That constant murmur is the sound of a thousand stories like this that don't (yet) have the coordination to hit the pages of the NYT at the same time and become "credible". A month ago, there were dozens of female founders sitting on stories like this who were still afraid to go public. And they were afraid because good, decent people like you, who "had never seen anything like it" would "dismiss it out of hand" if they told.
(Obligatory disclaimers: You don't need to believe every story 100% unconditionally, but "a constant murmur" = "multiple corroborating sources" and should not be ignored. Also, I want to praise rather than criticise the parent comment, because acknowledging why we were ignoring these stories is a vital first step to not ignoring the next one we hear.)
