Vaticle, formerly Grakn Labs, is a British company that came to market in October 2016. Its flagship product, TypeDB (previously Grakn), is open source and free to download, although the company also offers commercial licensing and enterprise support at a premium.
Historically, Vaticle’s solutions have found most success within the life sciences, telecommunications, and financial services sectors. That said, it is not exclusive to these industries. It is also notable that the company has found success with users migrating from other RDF graph databases, who have found the semantics of these environments too complex.
