- ✓Composable APIs (parse, embed, rerank, generate, ground) let teams swap in only what they need
- ✓Strong references in regulated industries (Qualcomm, ShipBob) with concrete ROI numbers
- ✓Built specifically for dense technical and regulatory documents, not generic Q&A
- ✓Cloud or VPC deployment for compliance-sensitive customers
Cons
- ✗No self-serve tier — every engagement requires sales contact
