Our startup, Selera Labs, is working on a product that sounds similar in some respects. We leverage elements of enterprise search and machine learning to provide continuous monitoring style analysis over ERP transactional data.
The human interaction component is something we have been very focused on. We support human annotations (tagging and workflow) over machine generated results that allow us to tune analysis processing for false vs true positives. We've also devoted lots of effort into making the UX easy for business users to very quickly understand why a result (or exception) was generated.
