Overview
Moving from Marketing Tools Growth Marketing Platform to Twenty CRM is a structural data migration with a significant schema preparation component. Marketing Tools Growth Marketing Platform exports Contacts, Companies, Deals, Segments, and Tags cleanly via its documented API endpoints; the platform does not export Workflow Journey definitions or campaign performance metrics. We migrate segment membership as tag-style data on each Person record and preserve the original segment name as a reference field. Custom Objects require a custom field-mapping phase during discovery because the platform's schema is not publicly documented. Twenty's open-source model means you own your data with full SQL export capability post-migration, eliminating the vendor lock-in that small and mid-market teams cite as a reason for leaving closed-source platforms.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Marketing Tools Growth Marketing Platform object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Marketing Tools Growth Marketing Platform
Contact
Twenty CRM
Person
1:1Marketing Tools Growth Marketing Platform Contact records map to Twenty Person records via a 1:1 field mapping. Standard fields (name, email, phone, company linkage) export cleanly via the platform's API. We resolve the contact-to-company relationship at import time by exporting contact-company pairs and setting the Person's company linked account during the Person insert phase. Any HubSpot owner email is resolved against the Twenty User table by email match.
Marketing Tools Growth Marketing Platform
Company / Account
Twenty CRM
Company
1:1Marketing Tools Growth Marketing Platform Company records map to Twenty Company records. The source domain field maps to the Company website field and acts as the dedupe key during import. Twenty's Company object currently has a minimal standard field set; industry, employee count range, annual revenue, and social profile fields do not exist by default and must be created as custom fields via the Twenty Metadata API before the Company import phase begins.
Marketing Tools Growth Marketing Platform
Deal
Twenty CRM
Opportunity
1:1Marketing Tools Growth Marketing Platform Deals map to Twenty Opportunity records. The Deal stage maps to a Twenty Opportunity status field; if the destination workspace uses custom status values, we configure those via the Metadata API before import. Deal amount, close date, and owner information migrate directly. We resolve the Opportunity's linked Company and Person at migration time via the contact-company pairs extracted during discovery.
Marketing Tools Growth Marketing Platform
Segment
Twenty CRM
Tag (custom field on Person)
1:manyMarketing Tools Growth Marketing Platform segment definitions are rule-based and platform-specific in syntax; the underlying rule logic cannot be exported. We extract the membership per contact (which contacts belong to which segments) and replicate that as a tag-style field on the Twenty Person record. The original segment name is preserved as a reference field so that the customer can rebuild the segment rule logic in Twenty or an external segmentation tool post-migration.
Marketing Tools Growth Marketing Platform
Campaign
Twenty CRM
Opportunity (campaign metadata)
lossyCampaign metadata (name, status, start/end dates, channel) exports from the platform. We import campaign metadata as Opportunity records with a campaign_type field set to distinguish them from deal-based opportunities, or we create a custom Campaign object via the Metadata API if the customer's campaign volume warrants it. Campaign performance metrics (open rates, click rates, attribution) are not available via standard export and are preserved as a separate reference CSV exported from the platform's analytics dashboard before cutover.
Marketing Tools Growth Marketing Platform
Workflow Journey
Twenty CRM
Not migratable
lossyWorkflow Journey definitions — triggers, conditions, branches, and action steps — live in the platform's internal automation engine and are not accessible via export. We cannot carry them over automatically. We document every active journey during the discovery call: we capture screenshots, list the trigger conditions, describe the branch logic, and note the action steps. This documented inventory is handed off to the customer's admin team with a recommendation to rebuild using Twenty's API-based workflow approach or an external automation tool within the first post-migration sprint.
Marketing Tools Growth Marketing Platform
Custom Object
Twenty CRM
Custom Object
1:1Marketing Tools Growth Marketing Platform Custom Object schema is not publicly documented in the available evidence base. During discovery, we attempt field-level mapping by querying the platform's live schema where accessible and by interviewing the customer's technical team. Where customers report custom object usage, we create the equivalent custom object in Twenty via the Metadata API before importing data. Lookup relationships to standard objects (Person, Company) are resolved at migration time using the relationship data extracted during discovery.
Marketing Tools Growth Marketing Platform
Tag
Twenty CRM
Tag (Person field)
1:1Tags export as flat key-value pairs per contact. We map them directly to Twenty's tag field on the Person record. We flag any tags that exceed Twenty's character limits before import and map them as comma-separated values within the field maximum. If the customer uses tags for content classification as well as contact segmentation, we note the dual usage during scoping and recommend separate fields for each use case.
Marketing Tools Growth Marketing Platform
Attachment
Twenty CRM
Not migratable
1:1File attachments associated with contacts or campaigns are not available via the platform's documented export path. We flag attachments as out of scope and recommend that customers export attachments separately via the platform's UI export feature before the cutover date. Attachments can be re-linked post-migration by re-uploading to Twenty and associating them with the corresponding Person or Company record manually or via the Twenty API.
Marketing Tools Growth Marketing Platform
Owner
Twenty CRM
User
1:1Marketing Tools Growth Marketing Platform Owner records map to Twenty User accounts. We resolve owners by email match. Any source Owner without a matching Twenty User goes to a reconciliation queue for the customer's admin to provision before record import resumes. Owner resolution must complete before any record with an OwnerId reference is imported.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Marketing Tools Growth Marketing Platform gotchas
Large bulk uploads cause UI timeouts
Journey automation logic is not exportable
Campaign performance metrics not available via standard export
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Discovery and schema audit
We audit the Marketing Tools Growth Marketing Platform account across contacts, companies, deals, segments, campaigns, workflow journeys, custom objects, and engagement volume. We pair this with a Twenty workspace assessment: we inspect the current custom field inventory, identify which standard fields are missing from the Person and Company objects, and plan the Metadata API calls required to pre-create them. The discovery output is a written migration scope, a field-level mapping spreadsheet, and a list of active Workflow Journeys requiring documentation for rebuild.
Custom field and custom object creation via Metadata API
Before any data import, we create all required custom fields on Person and Company via the Twenty Metadata API. This includes industry, employee count range, annual revenue, website, social profiles, job title, department, and any source fields that do not map to a Twenty standard field. If the customer has custom objects in the source platform, we also create the equivalent custom objects and their custom fields via the Metadata API. We use the Twenty API playground (Settings > APIs & Webhooks) to validate that the new fields appear in the schema before proceeding to the import phase.
Sandbox migration and reconciliation
We run a full migration into a Twenty test workspace using production-like data volume. The customer's admin reviews record counts (People in, Companies in, Opportunities in), spot-checks 20-30 random records against the source platform, and validates that custom field data populated correctly. Any mapping corrections happen in the test workspace before production migration begins. This step also confirms that the Metadata API field creation was successful and that the API playground reflects the expected schema.
Owner reconciliation and User provisioning
We extract every distinct Owner referenced on contact, company, deal, and engagement records and match by email against the Twenty workspace's User table. Owners without a matching User go to a reconciliation queue. The customer's Twenty admin provisions any missing Users before migration resumes. Owner resolution must complete before any record with an OwnerId reference is imported, because Twenty enforces relationship integrity on owner-linked records.
Production migration in dependency order
We run production migration in record-dependency order: Companies (from HubSpot/Platform Companies), People (with Company linkage resolved via the contact-company pairs from discovery), Opportunities (with Person and Company lookups resolved), segment membership data (as tag-style fields on Person records), and Tags. Each phase emits a row-count reconciliation report before the next phase begins. We use batch API calls of no more than 5,000 records per request to avoid platform UI timeouts. Custom objects migrate last if the customer uses them, because they often contain lookup relationships to standard objects that must already exist.
Cutover, validation, and Workflow Journey handoff
We freeze writes on the source platform during cutover, run a final delta migration of any records modified during the migration window, then enable Twenty as the system of record. We deliver the Workflow Journey documentation inventory to the customer's admin team with rebuild recommendations. We support a three-day hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Workflow Journeys as automation logic inside the migration scope; that work is handled by the customer's admin using Twenty's API-based workflow approach or an external automation tool.
