Why teams switch to Synaps
Your products are blocked by missing data
If listings fail because attributes, GTINs or categories are missing, Synaps fills those gaps automatically — where a feed manager leaves them stuck.
You want a higher publish rate, fast
Customers move from a ~60% publish rate to 95–99% by unblocking products that were previously rejected for incomplete data.
Your catalog is messy or multi-supplier
Synaps normalizes and completes inconsistent dropship and supplier data without manual cleanup.
You want to be found by AI search
Synaps optimizes product data for AI shopping surfaces like Google, Perplexity and ChatGPT — not just traditional marketplaces.
