I am Vincent, frenchman based in Germany. I am employed at derivo GmbH, a small company from Ulm that tries to convert ideas from the academic world into actual products.
Years ago, we used Neo4J embeded to store RDF data for our OWL-RL reasoning engine GraphScale. More recently we ported our SemSpect RDF Graph Browser to Neo4j and it is now available as a Graph App for Neo4j Desktop (for more details, see https://www.semspect.de/).
I hope to be able to help and learn something in return!
