Shuttio

Disclosure: Shuttio is built by the team behind weekcrm.

What it does

Shuttio is a migration tool with one destination, Attio, and five sources: HubSpot, Pipedrive, Affinity, Salesforce and CSV. It reads the source schema, lets you review every field mapping, and runs a free 50-record sample per object before the full move.

What makes it different

• Relationships survive. Records are created first and linked in a second pass, so a deal finds its company whichever arrived first.
• Re-runs don't duplicate. People match on email, companies on domain, custom objects on a key you choose.
• Field history is optional. On HubSpot and Salesforce a stage change from March still reads as March in Attio.
• Cancel is a real undo. It deletes everything the migration created, in reverse order, and never touches what was in Attio before.

When something else fits better

Shuttio covers five sources and one destination. If you are moving between two non-Attio CRMs, or from a source it does not support yet, a broad tool such as Import2 or a CSV import is the better answer.
