Uh, it's nice to see the name Actian come out for once.
My previous employer used Versant by Actian (now called Actian NoSQL) heavily.
It's much more of a NoSQL database: it's a real object oriented database. You don't store tuples, you store objects. You don't make queries with selection and projection, you make a cut of a graph of objects.
It's insanely fast, multithreaded, has very good tooling, scales vertically very well, can do online schema evolution (class definition evolution, really).
Sadly it's almost impossible to scale horizontally (I'd be glad to be proven wrong).
It's basically what the industry needs to avoid the object-relational mismatch: an object oriented database.

But everybody only learns SQL...
