HubSpot to Attio migrations

We move revenue teams from HubSpot to Attio when their needs are narrower than HubSpot's full Marketing + Sales + Service + CMS suite. Companies, deals, contacts, and custom properties carry over cleanly. Workflows and outbound sequences need a rebuild. HubSpot's marketing features (email blasts, landing pages, forms) don't come with us.

Why teams move

Why teams move off HubSpot

HubSpot is a strong fit for teams using the full Marketing + Sales + Service + CMS stack together. Teams move to Attio when their needs are narrower than that and the structural fit changes.

01 · Pricing

Plan structure mismatch

HubSpot pricing is tier-based with reporting views, automation triggers, and seat counts grouped onto higher plans. Clean fit when a team uses most of the suite; heavier spend when the team mainly needs CRM plus a few workflows.

API surface

HubSpot's API has grown across many product lines, so the surface is broader and more varied. Attio was built API-first against a single data model, which makes integration code shorter and easier to reason about. For teams building custom integrations or complex automation, the consistency adds up.

03 · Scope

Suite breadth carries overhead

For CRM-focused teams, HubSpot's marketing / service / CMS surface adds configuration, training, and billing overhead that does not translate into daily value. A narrower CRM is sometimes the right answer.

Migration playbook

How we run the migration

We use three principles and six numbered steps to run a typical 2 to 4 week HubSpot migration. The upfront kickoff sets the dated plan, and most of the project time goes into workflow rebuilds and team feedback.

Upsert on HubSpot legacy IDs

Imports keyed on HubSpot record IDs, not on email or domain. Multiple passes never duplicate. Completeness checks are deterministic.

Merge at the end

Merging removes legacy IDs, so we import everything, confirm coverage, and then run deduplication and merge once.

Audit before rebuild

Migration is the right moment to retire unused workflows. We rebuild only the workflows the team actually depends on in Attio.

  1. 01

    Kickoff and attribute review

    We start with a working session to agree on the data model and confirm scope. The engineering team walks every property, custom object, list, and workflow definition in HubSpot and decides what stays, what gets renamed, and what gets retired.

  2. 02

    Schema build and static import

    We configure the Attio workspace around the agreed schema and run the first import as a dry run. The import is keyed on HubSpot legacy record IDs so that completeness checks stay deterministic across multiple passes.

  3. 03

    Configuration, training, and feedback

    We configure lists, views, and day-one integrations, and then the team connects their inboxes so interaction history can backfill. We set email-sharing preferences before launch, choosing between metadata-only, subject plus metadata, or full access.

  4. 04

    Cutover

    Cutover happens in a short blackout window, usually on a Sunday. We run the final HubSpot export, then upsert the delta against the legacy record IDs. We validate the result against record counts, per-field population, and value-level spot checks, and we pause any tool that writes to Attio for the duration of the window.

  5. 05

    Workflow rebuild and deduplication

    We rebuild the workflows the team actually depends on, and the rest get retired. We then run the deduplication pass through Attio's Duplicate Detection app, the team reviews the matches, and we bulk merge through our tooling. The legacy record IDs are removed once the merge is complete.

  6. 06

    Phase two (optional)

    Phase two covers the deeper integrations, advanced reporting, and the warehouse plus BI layer for reporting beyond native dashboards. Most teams run Attio for a few weeks before deciding which of these are worth scoping.
