Overview
SalesSeek organizes customer data around contacts, organizations, deals, and tasks in a relatively flat schema. HubSpot uses a richer object model with contacts, companies, deals, tickets, and engagement records (calls, emails, meetings, notes). The core migration challenge involves translating SalesSeek's organization-centric model to HubSpot's company-contact hierarchy, preserving deal stage and pipeline context across systems, and handling custom field types that map differently between platforms. We pull data from SalesSeek via their REST API (paginated, with configurable field selection), transform field values to match HubSpot property types, and load via HubSpot's import API. Workflows, email sequences, and automation rules in SalesSeek do not migrate — those must be rebuilt using HubSpot's workflow builder and sequences tool after go-live. The migration carries all standard objects (contacts, organizations, deals, tasks), custom fields, attachments (re-uploaded to HubSpot Files), and activity timestamps with original owners preserved via email match.
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 SalesSeek object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
SalesSeek
Contact
HubSpot
Contact
1:1SalesSeek contacts map directly to HubSpot contacts. The primary organization association becomes the HubSpot company link via the contacts_company association. When SalesSeek contacts associate with multiple organizations, we select the most recently modified organization as the primary HubSpot company link and preserve all other organization associations as secondary HubSpot company associations so no relationship data is lost during the migration.
SalesSeek
Organization
HubSpot
Company
1:1SalesSeek organization records map 1:1 to HubSpot companies. Organization name becomes company name, domain maps to website field, and industry/location fields map to HubSpot's standard company properties. Custom organization fields become HubSpot custom company properties, preserving any custom data your team has built up over time.
SalesSeek
Deal
HubSpot
Deal
1:1SalesSeek deals map to HubSpot deals. Each SalesSeek pipeline maps to a corresponding HubSpot deal pipeline. Deal stage names map value-by-value to HubSpot stage labels. Amount, close date, owner, and custom deal fields transfer directly, preserving the full deal history and pipeline context from SalesSeek.
SalesSeek
Pipeline
HubSpot
Deal Pipeline
1:1SalesSeek pipelines become HubSpot deal pipelines. The migration plan includes pipeline creation in HubSpot before the import runs. Stage order, labels, and probability values are mapped per pipeline. HubSpot's stage delay (days in stage) is set based on SalesSeek's stage configuration, maintaining your historical pipeline metrics.
SalesSeek
Task
HubSpot
Task
1:1SalesSeek tasks map to HubSpot tasks. Task subject, body, due date, owner (resolved by email), and completion status transfer. Both open tasks and completed tasks migrate. Notes attached to tasks become HubSpot engagement notes, maintaining the full task context in HubSpot.
SalesSeek
Call / Email / Meeting (engagement)
HubSpot
Engagement (Call / Email / Meeting)
1:1SalesSeek call logs, email records, and meeting records map to HubSpot engagement records. Original timestamps, owners, and associated contacts and companies are preserved through HubSpot's engagement associations, linking activities to the correct contact and company records in HubSpot.
SalesSeek
Custom Field (Contact-level)
HubSpot
Custom Property (Contact)
1:1SalesSeek custom fields on contacts require pre-created HubSpot custom contact properties. Field types are matched precisely — text to single-line text, number to number, date to date, picklist to picklist. Multi-select picklists in SalesSeek map to HubSpot's checkbox or multi-checkbox property types to preserve multiple-value selections.
SalesSeek
Custom Field (Deal-level)
HubSpot
Custom Property (Deal)
1:1SalesSeek custom deal fields become HubSpot custom deal properties. The migration plan includes the full list of custom deal fields needing HubSpot property creation before import. Deal-level custom properties that drive pipeline logic are flagged for priority schema setup to ensure your automation rules work correctly after go-live.
SalesSeek
Attachment / File
HubSpot
HubSpot Files
1:1SalesSeek file attachments on contacts, organizations, or deals are downloaded and re-uploaded to HubSpot Files. Files are associated to the corresponding HubSpot records via file associations, maintaining the attachment context in HubSpot. HubSpot's 115MB file size limit applies to each re-uploaded attachment.
SalesSeek
User / Owner
HubSpot
User
1:1SalesSeek owner IDs are resolved to HubSpot users by matching owner email addresses against HubSpot user accounts. Unmatched owners are flagged before migration. You can invite unmatched owners to HubSpot before the migration or assign their records to a fallback HubSpot user — no record lands in HubSpot without a resolved owner.

Migration approach
Audit SalesSeek data and map to HubSpot schema
We extract a full data export from SalesSeek via their REST API covering contacts, organizations, deals, tasks, and custom fields. We then generate a schema mapping plan that identifies which HubSpot properties map directly, which need custom property creation, and which require value mapping or transformation. This plan is reviewed with you before any migration step runs, ensuring full visibility into the mapping logic.
Create HubSpot custom properties and deal pipelines
Before data loads, we create all custom contact, company, and deal properties needed for the migration, matching the field types from SalesSeek. Deal pipelines in HubSpot are created to mirror the SalesSeek pipeline structure, including stage names, probabilities, and order. This step requires HubSpot admin credentials or a delegated admin session to complete the schema setup.
Resolve owners by email and flag unmatched users
SalesSeek owner IDs are matched to HubSpot users by email address. We generate a pre-migration owner resolution report showing matched users, unmatched owners, and a recommended fallback assignment. Your team either invites unmatched owners to HubSpot or approves fallback assignment before the migration proceeds. No record lands in HubSpot without a resolved owner, ensuring attribution continuity.
Run sample migration with field-level diff
A representative slice of 100–500 records migrates first, covering contacts across multiple organizations, deals in each pipeline, and a sample of activities. We generate a field-level diff showing source value, mapped HubSpot value, and any transformation notes. You verify lifecycle mapping, organization-company linking, deal stage mapping, and owner resolution before the full run commits.
Execute full migration with delta-pickup window
The full migration loads all SalesSeek records into HubSpot. A delta-pickup window (24–48 hours) captures any records created or modified in SalesSeek during the cutover period. An audit log records every operation, and one-click rollback is available if reconciliation identifies unexpected discrepancies. Your team continues working in SalesSeek throughout the migration window.
