Scripted, reversible, lossless. Companies, contacts, deals, custom properties, associations, timeline activities. Fixed price from $4,500. We've shipped this 23 times.
HubSpot's data model was built for inbound marketing funnels. Your pipeline doesn't look like that anymore — if it ever did. Companies and Contacts are tethered to funnel stages, not relationship depth or account health. Custom objects exist, but the UX is painful. You spend more time wrangling schemas than selling.
Pricing compounds the problem. You start with Sales Hub at $90/seat. Then you add Marketing Hub for demand gen, Operations Hub for workflow automation. Suddenly you're paying $300+ per user for features whole teams don't touch. At 15+ seats, you're hemorrhaging $4K+ monthly on tool sprawl.
The workflow ceiling hits hardest at scale. HubSpot workflows are fine for 10 automations. At 50+, they become unmaintainable — hidden dependencies, impossible to debug, pure technical debt. You can't see the full picture. You can't reuse logic.
Pipeline stages don't bend to how you actually sell. Consultative deals need multiple stakeholders tracked per opportunity, not just contact roles. Relationship-shaped sales need account history and relationship signals, not lead scoring. You're forcing your sales process into HubSpot's template, not the other way around.
We've shipped 23 migrations off HubSpot. Every team cited at least one of these. HubSpot is the right choiceif you're running a marketing-led funnel at SMB scale. It's excellent at that. But if you're doing outbound, account-based sales, or complex stakeholder navigation, you're fighting the tool. Attio is built for exactly that — flexibility first, structure second.
HubSpot's five core objects move into Attio with full fidelity. Your data doesn't get stripped down or reinterpreted — custom properties, associations, and ownership all transfer intact. The key is understanding which HubSpot fields map to which Attio attributes so you know exactly what lands where.
Companies become Attio organizations. Names, domains, annual revenue, lifecycle stages, and all custom properties carry over. Account owners are matched by email and reassigned automatically. Associations stay locked in place.
Contacts become Peoplein Attio. Email addresses, phone numbers, job titles, and company associations transfer cleanly. Lifecycle stage maps to Attio's People stage field. Custom properties arrive as the same type, so your filtering and reporting logic doesn't break.
Deals move as-is. Names, amounts, owners, and stages transfer directly. Custom properties carry their type and values. Associations to companies and contacts are preserved, so every deal still knows which organization it belongs to.
Notes and Tasks become Attio timeline activities. Every note your team wrote stays attached to the right company or contact. Task due dates, assignees, and descriptions transfer.
Custom properties carry their type fidelity — numbers stay numbers, single-select dropdowns stay dropdowns, multi-select fields stay multi-select. Owners are mapped via email matching.

We're direct about this on every kickoff call: HubSpot has features Attio doesn't replicate one-to-one. Here's what you'll need to handle separately.
Your automation engine doesn't move over. HubSpot's workflow builder has no API export, so you're rebuilding the logic in Attio Workflows by hand. Take your top 5–10 workflows (the ones actually running revenue motions). Most clients rebuild these in 2–4 hours. Everything else usually gets killed — dead workflows are dead for a reason.
Attio is a CRM. It has no email or sequencing tool. You need a separate platform — Lemlist for personalized cold outreach, Apollo for inbound sequences, or keep HubSpot's email engine running in parallel during transition. We wire one in as part of the Migration + Wire package.
HubSpot's lead score field comes over as a number. The scoring logic doesn't. You rebuild scoring in Attio using formula attributes (engagement history, company size, industry flags) or outsource it to Clay enrichment. This takes an afternoon to set up properly, then runs on autopilot.
Attio's reporting is solid. Your saved HubSpot dashboards are not. You'll lose custom report layouts, saved filters, and dashboard arrangements. Budget half a day to rebuild your top 5 dashboards from scratch. After that, Attio's dashboard interface is usually faster to work in than HubSpot's.
Every HubSpot-to-Attio migration runs the same four-step process. We've run it 23 times. It's methodical, boring, and reliable.
We screen-share into your HubSpot workspace and walk through it together. We catalogue every object, custom property, workflow, and integration you have. Nothing gets assumed; we see it. By the end, we hand you a one-page scope doc with the field map. Takes 2–3 hours.
We build your Attio data model offsite. Objects, attributes, views, permissions. We send it to you in draft form. You read it, flag any changes, we iterate. No data moves until you sign off.
Cutover day itself is where the work happens. We run a dry-run first against a copy of your data. Our own AI-powered system maps every record, flags conflicts, and prints a diff showing you exactly what will change. You review it. Once you approve, we apply the real migration. Actual data move is usually under 30 minutes.
Record counts, association integrity, owner mapping, custom-field values. We screen-share the verification with you. You sign off. Then a runbook plus a Loom walkthrough of every workflow we built.
One day. That's the standard for a typical HubSpot Sales Hub migration — the cutover window runs start to finish in a single business day. Complex migrations with custom objects, multi-pipeline workflows, or heavy formula logic run 2–3 days. Both scenarios are rare in practice.
Most SERP articles quote 2–3 weeks because they're describing manual imports without scripted tooling. No automated diff checks, no batch validation, no structured verification. That's not a timeline issue — that's a process issue.
We've shipped 23 of these. The cutover window has been under 30 minutes on every one. The hour-by-hour breakdown:
| Hour | Phase | What happens | Who owns it |
|---|---|---|---|
| 09:00 | Kickoff call | Confirm scope, walk through dry-run plan, set rollback criteria | WeScaleUp + you |
| 09:30 | Dry-run | Run mapping against sandbox copy. System prints full diff and conflict list | WeScaleUp |
| 10:30 | Diff review | We screen-share the diff. You approve, flag any changes, or pause | You |
| 11:00 | Apply migration | Live write to Attio. Usually under 30 minutes for typical workspace | WeScaleUp |
| 11:30 | Quick checks | Record counts, association integrity, owner mapping spot-checks | WeScaleUp |
| 13:00 | Workflow rebuild | Top 5–10 HubSpot workflows rebuilt as Attio Workflows | WeScaleUp |
| 15:00 | Verification walkthrough | We walk you through 10 representative records — you confirm | WeScaleUp + you |
| 16:00 | Sign-off + handoff | Runbook delivered. Loom recordings sent. 30-day support window opens | WeScaleUp |
You pay by scope, not hours. Your migration cost is fixed. Your cutover date is fixed. No surprise invoices when we optimize your field mapping or add extra workflows — the scope defines the price.
Hourly billing creates a problem: the slower we work, the more we earn. Fixed pricing flips that. We're incentivized to finish fast and clean.
Most teams use Standard ($4,500). If you're consolidating Lemlist, Apollo, or Clay data flows, Migration + Wire ($7,500) includes those integrations. Complex deployments — multi-pipeline HubSpot with custom objects, 50+ workflows, or Salesforce-scale requirements — start at $9,500.
Every package includes the field map, the dry-run, the cutover, post-launch verification, runbook, and 30 days of follow-up support.
