Nothing moves until you have seen it

Dataferry connects the HubSpot and Salesforce accounts you own, then asks you to confirm every Contact field: split, join, date, currency, value-map and text-template transforms, with AI suggestions when a mapping worker is configured. You preview the result on sample records and approve that exact plan; approval expires after 15 minutes and is invalidated by any change.

A transfer that checks its own work

The run pages through source Contacts, upserts each one by a unique External ID and reads it back before counting it done. Progress, per-Contact results, pause, cancel and retry are built in, and a retry updates rather than duplicates. Email or webhook notices report when a run finishes, and reviewed mappings can be saved as templates and shared.
