This is pretty interesting. I'm curious what issues this design language addresses that other design languages (like Material or IBM Design) don't address.

I'm currently working with Ant and it's designed more for enterprise applications. It has a huge component library and great documentation, even though some of it has to be translated from Chinese. The components really cover a lot of use cases. There are some great chart libraries as well.

Material is mostly optimized for mobile applications and interactions. It requires a lot more space which starts to fall apart with the needs of a more complex application.

When you say it’s designed for enterprise applications, what does that mean? How would that be different then non-enterprise applications?

By enterprise I mean something that's more of a SaaS application vs more of a website.

Material requires more space than something like a Salesforce, for example will allow.

It's one of the reasons Google hasn't implemented material design with Gmail. Too much going on in one space for it to work.

Not immediately obvious from browsing the page.. does it React?

Yes!
