Where Profound wins
If your RFP says “GEO platform” with SSO, broad engine coverage, and conversation-level competitive research, Profound is built for that conversation. SellOnLLM will not claim to replace that stack on day one.
Where SellOnLLM wins
- Zero friction. Share a free result with your boss before any procurement.
- Audit ↔ visibility. Diagnose why a PDP fails AI readiness while checking mentions.
- Commerce. Shopify AI analytics sits next to visibility—not only share-of-voice charts.
- Price for the long tail. Most brands that bounce after one scan never needed Enterprise.
