Some of my friend went to it a few weeks ago in Austin. From what I've gathered some people were just excited that Austin had a lot of Black people congregating around one event. It may have been good for some networking, but I was told that the sponsorship was a lot of tech adjacent companies (banking, medical, etc) and not a lot of tech companies sponsoring. Also some people there weren't exactly in tech, but rather loved the idea of tech culture.
It's a very young conference though so maybe in due time it will get better. I'm all for supporting Black. I went to a Black Men's Summit in Dallas a few weeks ago, but sometimes these events are flash over substance.
