First thing in my mind when I found your product:

Could we use TerminusDB to store RDF data?
Is it possible to run SPARQL queries?
If I use this, am I locked in, or could I change to something else that uses RDF?
... or easily move my data from something else to TerminusDB?
more concrete: could I export TerminusDB content into JSON-LD files stored in a git repo (or import from that)?

Hello! I'll try to answer in order:

Yes - we store all data internally as RDF
Not without work - WOQL is similar but different to SPARQL - it is possible to implement a SPARQL query engine but we haven't gotten around to it
You can dump RDF and use elsewhere, or you can dump JSON and use in something like Mongo - so actually you probably have more exit options than most databases.
See above
We can ingest JSON-LD and elaborate to JSON-LD internally but we actually don't have a flag to return it to the user at the moment. This is actually a relatively trivial feature addition but isn't there yet.

Hello Gavin, I see that Terminus DB recently add support for GraphQL. Do you have plan to add SPARQL support as well?

We don't have active plans to add SPARQL support, but it would not be a particularly hard project to do so.
