I was linked to a very interesting post on Referral Candy which I thought people here might appreciate:

Here are twenty-seven startups and support systems which are led by (and mostly focused on) women, people of colour, and LGBT+ people.

Many of these companies/groups are focused on the tech industry (understandably, considering the well-documented white male dominance of that field), but some have other interesting directions as well.

This kind of signal boosting is, I hope, a good way I can help.
