It is very likely. My wife is a very well respected Engineer in her field and when she was asked to come out of retirement, she retired to start a farm and enjoy the outdoors, they called her back and made what I thought was a very low offer. She was going to accept it because to her it was a work from home gig and was near what she used to make. I said no and helped her negotiate an additional 30% in her rate that she would have simply left on the table because she didn't feel comfortable asking for more.*

*Yes, anecdotal evidence but I hear it from her and her female engineering friends a lot. To the point I've offered to help any of them negotiate their contracts in the future.

I agree with squozzer, you should consider expanding your activities beyond folks who know you personally.

I really like my work and I work a lot. I have worked in early-mid stage startup and now am working with a pre-series A stage startup. I have never shied away from asking for more responsibilities or climbing up the management chain. I am generally known as the more assertive person in the organization. But when it comes to compensation, I cannot bring it up. Not sure if it has to do with being a female.

It would be ideal if there was a 'go to' person who can push me more in negotiating for better compensation.

You may have found a calling. I hope you consider expanding the scope of your activities beyond your wife's friends. What would make it worth your while?

Well, the two variables your subjects have in common is being engineers as well as being female. Personally (being a male engineer), I'd say being a bad negotiator has just as much to do with being an engineer as being a woman (except if women engineers are even worse negotiators than I am).
