Competitive landscape

Edge: Trained on a large behavioral-health quality database and sold into plans that already struggle with unstructured notes.

ROI percentages in the PR are vendor-reported; diligence should request plan-level methodology and contract value.

    Strong on structured claims; weak on unstructured notes.
