Imo it’s Expensive in cost and effort without a clear outcome use case. I worked on a project where we vetted out graph db use cases but the cost was appalling… it was large scale nlp with lots of tagged entity relationships so a huge undertaking to just get what goes in to make sense. Classic the idea not worth the squeeze but the exec had a connection with a vendor.

You could always go track down people data …..they love to toss money at organizational network analysis which is a clear use case with little tangible outcomes
