CRM evaluation
Attio vs HubSpot: Compare the Customer Model Before You Migrate
Choose the CRM that can represent your customer relationships, keep each team’s next action clear, and update the right records when your data changes. A polished contact screen will not answer those questions. One person working across two customer engagements will.
This guide gives you the same small exercise for Attio and HubSpot, with a worksheet for recording what actually happens. Start with your current CRM. If it already handles the exercise, fixing a confusing field or an unowned process may be a better next step than moving your data.
Trellus publishes this comparison and has a commercial interest in sales software. Vendor details were checked against the six linked first-party guides on October 28, 2026. The exercise below is a proposed evaluation with fictional records; it is not a report of hands-on testing in either CRM.
Decide where a fact belongs
Morgan’s email belongs to Morgan. “Send the revised launch plan” belongs to one engagement. “External adviser” describes Morgan’s role in another engagement. Put all three on a single person record without distinguishing their context, and a rep may find the right person with the wrong next action.
Attio separates object records, list entries and views. A list can hold process-specific values without changing the underlying record; a view filters or displays existing data. Custom objects and custom relationship attributes require Pro or Enterprise. Admins create custom objects, while creating attributes requires full access to the relevant object or list. These are useful choices to evaluate when your team needs different process context around shared records. Read Attio’s data-model guide.
HubSpot uses objects, records, properties and associations. Associations connect records of the same or different object types. Its available objects include contacts, companies, deals and other business processes; some require Super Admin activation. Custom objects require Enterprise and Super Admin creation. Creating custom association labels requires Professional or Enterprise. Check the suitable objects already available in your subscription before deciding that the exercise needs a new custom object. Read HubSpot’s objects and associations guide.
The practical question is who can explain the model to the next person on the team. Ask a second user to find Morgan, identify both engagements and name the owner of each next action. If they need the administrator beside them, write down which part was unclear before changing tools.
One person, two concurrent engagements
Use a separately approved test workspace and fictional data. Give the administrator this brief before either product demonstration, so both vendors answer the same question.
| Record or relationship | Fictional detail | What must stay separate |
|---|---|---|
| Person | Morgan Lee, morgan@example.com | One person identity, linked to both engagements |
| Engagement A | Example Company launch; owner Alex; next action: send revised plan on Day 3 | Its owner, next action and due date |
| Engagement B | Example Company renewal; owner Sam; next action: review scope on Day 5 | Its owner, next action and due date |
| Morgan’s participation | Customer sponsor for A; external adviser for B | A role attached to each engagement, rather than a single global role |
| Later update | Morgan’s email changes to morgan.new@example.com | The same person and both engagement links after the update |
“Engagement” is the business requirement, not a prescribed object name. Ask each administrator to choose a suitable existing object first. If they propose a custom object or an extra participation record, have them explain the missing requirement, the subscription needed and who will maintain it. Two similarly named people are not a substitute for representing one person’s two roles.
- Draw the relationships before adding fields. Show one person, two engagements and the role on each connection. Mark which facts should change everywhere and which should change in only one engagement. Agree on that drawing before reviewing either interface.
- Record the chosen model. Write down each object or list, its identifier, the relationship used for Morgan’s participation and the location of each next action. Ask how the setup behaves when a third engagement starts. A design that needs another copy of Morgan should prompt another look.
- Find the work as a second user. From Morgan, locate A and B. From A, locate Morgan’s role, Alex and the Day 3 action. Then do the same for B, Sam and Day 5. Record the actual steps and any information the second user could not find.
- Prepare a small update. Keep the original system’s stable person identifier with the changed email. Identify the exact destination field and matching option before importing. An identifier from Attio is not automatically a HubSpot identifier, or the reverse; keep a cross-system mapping if migration is part of your exercise.
- Inspect the result. After an approved test update, compare the person count, original record identifier, both links, roles and engagement actions. Record error messages and unexpected additions. A green import notification alone does not establish that Morgan’s relationships survived.
- Inspect an approved export. Ask another person to identify Morgan, both engagements and their roles using only the exported files and field notes. List anything they cannot reconstruct. Keep the source records until the team has accounted for those gaps.
The expected business outcome is one Morgan, two correctly described roles and two independently owned next actions. Leave the observed outcome blank until someone runs the exercise. Neither product receives a pass from its documentation alone.
Check the update path, not just the initial import
Attio’s CSV guide describes matching updates with unique attributes. Record IDs and list Entry IDs update matching existing items; unmatched IDs are skipped. Missing unique identifiers on linked objects can create additional records. Empty imported values do not clear existing data, and multi-value updates add values rather than replace them. CSV import is available across plans with the appropriate admin or object/list write access, but does not import tasks or notes. Check Attio’s current CSV rules.
HubSpot documents contact matching by email and company matching by domain for specified creation and import paths. Imports can use Record ID or a property that requires unique values to identify existing records. Missing identifiers can create new records, and multiple existing matches can cause import errors. Company records created through the API, including third-party sync apps, are not deduplicated by company domain. Check HubSpot’s matching and deduplication rules.
For Morgan’s changed email, ask the administrator to explain the match before running the file. Then compare the actual original and resulting record identifiers. Add a deliberately missing identifier only in a separate approved test, with the expected behavior written down first. Keep that result apart from the correctly identified update.
Also distinguish replacing a value from adding another value. If your requirement is “remove the old role,” a file that merely adds a second role has not completed the job. Test the exact field type and import path you intend to use; the two vendors’ options are not interchangeable.
Include the people who administer and export the data
A comparison run entirely by an administrator can hide a daily ownership problem. Name who will change the model, who can update records and who is permitted to export them. Ask that team to repeat its part of the exercise under the intended roles and subscription.
Attio’s table and kanban view exports use the columns or card attributes included in the view. Shared filters need to be saved for the export selection. Members can export record views and members with view access can export list views by default; Enterprise admins can restrict exports to admins. Attio-enriched values are excluded, while manually supplied data is included. Review Attio’s view-export behavior.
HubSpot record exports require Export permission and contain current property values and selected associations. The export options determine which properties and associations appear; the all-associated-records option uses CSV. Calls, notes and other contact activities have separate export paths. Review HubSpot’s record-export behavior.
A spreadsheet opening successfully is only the start of the portability check. Look for the stable identifiers, role labels, association details and values that your next system will need. Record what is missing, including activity history or enriched values when those matter to your team. Neither of the specific export paths above should be treated as a complete account backup.
Keep a decision sheet with evidence
Copy this table into your evaluation notes. Put an observed result and its location in each product column. “Not observed” is a useful answer: it gives the administrator or vendor a specific question to resolve.
| Requirement | Attio result | HubSpot result | Evidence to keep |
|---|---|---|---|
| One person, two engagements | Not observed | Not observed | Person identifier and both engagement links |
| Different role in each engagement | Not observed | Not observed | Role location and how a second user finds it |
| Independent next actions | Not observed | Not observed | Alex’s Day 3 action and Sam’s Day 5 action |
| Email update preserves identity | Not observed | Not observed | Matching option, before/after identifier and person count |
| Intended users can do their jobs | Not observed | Not observed | Exact plan, role, permission and task performed |
| Export preserves required context | Not observed | Not observed | Export options, readable links and omitted-data list |
| Change has a clear owner | Not observed | Not observed | Administrator, unresolved gap and next step |
Agree on essential requirements before discussing a winner. A missing role relationship may matter more than several convenient fields. Keep the requirement, observed gap and cost of changing the process in the same decision note, rather than turning every difference into an equally weighted point.
When to choose Attio, choose HubSpot or keep what you have
Choose Attio when its record and process model fits the exercise, the team can maintain the chosen lists and relationships, and the necessary subscription and administrator are accounted for. Ask the future users to find the two roles and actions themselves.
Choose HubSpot when the objects and associations available to your team represent the same requirements and its current processes give each engagement a clear owner. Do not assume a custom object is necessary until you have reviewed the suitable existing objects.
Keep your current CRM when it passes the essential checks and the real problem is an unclear field, an unowned task or a neglected data-cleanup process. A migration will still require someone to resolve those decisions.
If your CRM already fits but the team needs a different calling workflow, evaluate that separately. Trellus’s Attio page and HubSpot page describe the respective calling workflows. Use the page for the CRM you actually work in and check its prerequisites; this relationship-model comparison does not establish calling behavior in either product.
Before committing to a move, have the CRM owner sign off on three things: the chosen relationship model, the observed update result and the export gaps the team is willing to accept. That leaves you with a decision you can explain after the demo ends.
