I think we, DEV, strive pretty hard to be a good place for women to work. We try our best. 🙂
I don't want to speculate too much on other companies, but Microsoft seems to really have evolved into a kind and inclusive company (but it's a gigantic corp, so there is probably no one Microsoft culture).
Some companies put inclusion front end center in loud ways from their founders. npm comes to mind.
Inclusion is a multivariate issue, so some folks might be a healthy environment for women, maybe not so much women of color etc.
In terms of resources in this regard, folks may want to check out keyvalues.com/
You can also read some of @lynnetye
's DEV posts on her profile. K/V will be a good resource for years to come.
I heard AMD is that kind of place.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
