Zebi is a big data platform with blockchain tech integrated with it. They have heavy ties to India but their team has experience all over in the US and other countries too. With such a large, connected, and public team I don't think they are that shady. However, this project looks like many of the other ones I've encountered before... so many damn buzzwords and connecting AI + Big Data + VR + Clean Energy + Blockchain (i'm exaggerating but you get my point). At least they're making progress on their roadmap and their social communities are active and being tended to.
