HubSpot to Attio migration

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.

02 · API

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.

Object by object

What migrates from HubSpot to Attio

The standardized taxonomy: Direct mapping (carries over cleanly), Caveats (needs a schema decision or rebuild), Unavailable (cannot transfer; plan around it).

Companies

Direct mapping

What's different

HubSpot can associate contacts with companies by matching email domains. Attio also creates or matches companies by domain, and domain is the main key used for company deduplication.

How we handle it

We bring HubSpot custom properties over as Attio attributes. Attio's domain matching and native enrichment replace much of the manual upkeep, or the third-party enrichment work, that teams often maintained around HubSpot company records.

Contacts / People

Direct mapping

What's different

HubSpot contact records often include Lifecycle stage and Lead status as standard operating fields. Multi-company relationships are usually limited to one primary company association.

How we handle it

We migrate contact properties as Attio attributes. Lifecycle tracking becomes a status attribute or list membership in Attio. When people genuinely span multiple companies, we model those relationships with reference attributes.

Deals

Direct mapping

What's different

HubSpot and Attio both support deal records with pipeline stages, values, and associated contacts and companies. Both platforms can represent multiple pipelines.

How we handle it

We migrate deal stages, values, and record associations directly. Pipeline structure maps cleanly into Attio when the source pipeline is already well-defined.

Notes & Tasks

Direct mapping

What's different

HubSpot records notes, tasks, and activities against contacts and companies. Attio supports notes and tasks with record associations, and email and calendar activity flows in from connected accounts.

How we handle it

For notes that touch several records, we usually attach the note to the company and include the related participants in the body. We preserve the original created date where possible. Because Attio's API does not allow the original creator field to be set, we include the original creator name in the note text.

Email & Calendar history

Caveats

What's different

HubSpot email tracking depends on connected inboxes and plan capabilities. Attio's native inbox and calendar sync can pull existing history once users connect their accounts.

How we handle it

Active users' history reappears after they connect their inboxes and calendars. Departed-user mailboxes that have been deprovisioned cannot be backfilled through sync. When needed, we preserve departed-user email metadata in a custom Interaction object.

Workflows & Sequences

Caveats

What's different

HubSpot includes Workflows and Sequences, with availability varying by tier. Attio also includes native automation and sequencing, but workflow definitions cannot be migrated between the platforms through an API.

How we handle it

We use the migration to identify workflows that still matter and retire the ones the team no longer uses. The remaining workflows are rebuilt manually in Attio. Teams that rely on advanced outbound sequencing may keep a dedicated sequencing tool alongside Attio.

Files & attachments

Caveats

What's different

HubSpot has a centralized file manager. Attio's Files tab supports uploads and linked cloud-storage folders from services such as Drive, OneDrive, Dropbox, and Box.

How we handle it

We export files from HubSpot, organize them by company in Drive or OneDrive, and link those folders to the Attio company records. Going forward, file management usually moves to the linked storage system.

Enrichment

Caveats

What's different

HubSpot enrichment depends on tier, and many teams supplement with providers such as ZoomInfo, Clearbit, or Apollo. Attio provides native enrichment that continues to update inside Attio.

How we handle it

We do not migrate third-party enrichment values as durable source data, because they can become stale once the vendor relationship changes. We use Attio's built-in enrichment as the baseline and add Apollo, Clay, or People Data Labs where deeper coverage is needed.

Reporting

Caveats

What's different

HubSpot Professional and Enterprise include custom reporting with Insight, Funnel, and Historical-values reports. Attio's native reporting covers the common operating views but does not replace every advanced reporting workflow.

How we handle it

We cover day-to-day visibility with Attio views and dashboards. Multi-axis reporting, scheduled reporting, or external-stakeholder reporting is better handled through a data warehouse paired with Metabase, Hex, or Looker.

Marketing features

Unavailable

What's different

HubSpot includes marketing features such as email marketing, landing pages, forms, blog hosting, and ad management. Attio is not designed to replace those marketing modules.

How we handle it

We keep a dedicated marketing or email tool connected to Attio. For form submissions, we recommend Fillout because it gives most teams the right balance of cost and Attio compatibility.

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.

Principle 01

Upsert on HubSpot legacy IDs

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

Principle 02

Merge at the end

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

Principle 03

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.

HubSpot to Attio migration FAQ

Eight questions we hear most often from revenue teams scoping a HubSpot to Attio move.

How long does a HubSpot to Attio migration take?

Most straightforward engagements run 2 to 4 weeks from kickoff to go-live. The time goes into schema design, workflow rebuilds, and team feedback. Heavier workflow rebuilds, deep custom property cleanup, or multi-portal HubSpot setups extend that. We give you a dated timeline at the start of the project, before any data moves.

What about HubSpot Workflows and Sequences?

Workflows and Sequences exist in both products but the migration is manual. There is no API path to move workflow definitions between platforms. We treat migration as the moment to audit and retire unused workflows, then rebuild the ones the team actually depends on in Attio's native automation builder. Many teams keep a dedicated outbound sequencing tool if they depend on features beyond Attio's native sequencing.

Does email history transfer from HubSpot to Attio?

Active users' interaction history rebuilds via Attio's native inbox and calendar sync, typically within an hour or two of connection. Departed-user mailboxes that are no longer connected will not backfill. We bring interaction metadata into a custom Interaction object via HubSpot's API to preserve the searchable signal where it matters. Plan access for departed-user records before the HubSpot subscription ends.

What happens to HubSpot's marketing features?

Attio is a CRM, not a marketing platform. Email marketing, landing pages, forms, blog hosting, and ad management do not migrate. Teams moving to Attio typically keep a dedicated email tool (Mailchimp, Loops, or even HubSpot Marketing as a standalone module) and connect it to Attio. For form submissions, we recommend Fillout over Typeform for cost and Attio feature parity.

Will we lose our HubSpot reports?

Attio's native reporting is functional but lighter than HubSpot's Professional / Enterprise report builder. For day-to-day views (pipeline by stage, owner workload, stale deals, recent meetings) Attio is enough. For multi-axis charts, scheduled report delivery, or external-stakeholder dashboards, we plan a data warehouse plus a dedicated BI layer (Metabase, Hex, or Looker).

What does the migration cost?

Scoped per portal. Cost depends on workspace volume (records, custom objects, custom properties), workflow count and complexity, integration inventory, permissions structure, and whether the team wants a clean migration or a broader rebuild. Book a discovery call and we'll walk through what your scope looks like.

Can you handle multi-portal HubSpot setups?

Yes. Multi-portal teams typically use separate HubSpot instances per fund, brand, or business unit. The Attio model consolidates these onto a shared contact graph with custom objects and list-level access controls so the teams stay segmented where they should be. We work the schema decision out during scoping.

Do you keep our HubSpot enrichment data?

We do not migrate third-party enrichment values (ZoomInfo, Clearbit, Apollo data inside HubSpot). Those fields go stale immediately after the firm stops paying the enrichment vendor. We rely on Attio's built-in enrichment for the baseline and layer Apollo, Clay, or People Data Labs where the data matters and stays fresh.
