Overview
Fello operates as a lightweight CRM with real-estate-specific enrichment: contacts with AI-generated lead scores, TCPA consent flags, and automated outreach tied to home-value data. Its data model centers on contacts, companies, and deals, with automation logic that handles drip sequences and follow-up triggers. HubSpot's CRM uses a richer object graph — contacts with lifecycle_stage, companies, deals tied to pipelines with configurable stages, and native activity tracking across calls, emails, meetings, and notes. When migrating from Fello to HubSpot, we map Fello's contact properties and custom fields to HubSpot contact properties, translating Fello's deal records into HubSpot deals with pipeline and stage values that mirror your original deal lifecycle. Fello automations — smart workflows, outreach sequences, and lead-scoring triggers — do not migrate; they must be rebuilt in HubSpot's workflow builder. We handle the data layer via HubSpot's native import API, using scoped read access on Fello so your team continues working through the cutover window. A 24–48 hour delta pickup captures any in-flight changes before final reconciliation, and our audit log documents every mapped field for compliance review.
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 Fello 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.
Fello
Contact
HubSpot
Contact
1:1Fello contacts map directly to HubSpot contacts. Each contact property in Fello becomes a corresponding HubSpot contact property. Fello's custom contact properties require HubSpot custom property creation before migration. Primary company association maps to HubSpot's company link on the contact record.
Fello
Contact.ai_lead_score
HubSpot
Contact (custom property)
1:1Fello's AI-generated lead score (0–100) has no native HubSpot equivalent. We create a custom number field (Fello_Lead_Score__c or as a HubSpot native property) and migrate the score value. Automation-based scoring rules must be rebuilt in HubSpot's workflow logic post-migration. During the migration, the current score is preserved exactly as it exists in Fello, maintaining your historical lead prioritization while you establish new scoring criteria within HubSpot's behavioral framework.
Fello
Contact.tcpa_consent
HubSpot
Contact (subscription status properties)
1:1Fello's TCPA consent flags store proof-of-consent dates and source. HubSpot's subscription and communication consent properties capture opt-in status but not the granular consent-source model Fello uses. We map Fello's consent status to HubSpot's opt-in properties and preserve raw consent data as a custom text field for compliance audit.
Fello
Company
HubSpot
Company
1:1Fello companies map to HubSpot companies. Company name, domain, industry, employee count, and annual revenue transfer as direct property mappings. Parent-child company relationships in Fello map to HubSpot's parent company field on the company record. We also handle any custom company properties created in Fello by generating matching custom fields in HubSpot and mapping the data during migration, ensuring complete company intelligence transfers.
Fello
Deal
HubSpot
Deal
1:1Fello deal records map to HubSpot deal records. Deal name, amount, close date, and owner assignment transfer directly. Fello's deal-stage values map to HubSpot pipeline stage values. Each Fello deal pipeline requires a corresponding HubSpot pipeline to be created prior to migration so stage pick-list values map correctly.
Fello
Deal Pipeline
HubSpot
Deal Pipeline
1:1Fello's pipeline configuration defines deal stages and order. HubSpot supports multiple pipelines per portal, each with independent stage sets. We create HubSpot pipelines to match Fello's pipeline configuration, preserving stage order and probability values as custom fields where HubSpot's native probability model diverges.
Fello
Deal Stage
HubSpot
Deal Stage (per pipeline)
1:1Fello deal stage labels map to HubSpot deal stage values within each corresponding pipeline. If stages differ between Fello and HubSpot, we apply value-by-value mapping. Stage-change timestamps are preserved as HubSpot deal custom datetime properties for reporting continuity. Each stage transition in Fello—including the date and time of moves between stages—transfers as a custom property on the HubSpot deal record, preserving pipeline velocity reports and forecast accuracy.
Fello
Smart Workflow
HubSpot
HubSpot Workflow (manual rebuild)
1:1Fello Smart Workflows do not migrate. They must be rebuilt in HubSpot's workflow builder post-migration. We export a Fello workflow definition document — trigger conditions, action steps, and filter logic — as a rebuild reference for your HubSpot admin or RevOps team.
Fello
Outreach Sequence / Email Drip
HubSpot
HubSpot Sequence (manual rebuild)
1:1Fello's automated outreach sequences and email drip campaigns do not transfer to HubSpot. HubSpot Sequences require manual setup: cadence steps, email templates, and enrollment triggers. We export sequence metadata from Fello for use as a specification document during HubSpot Sequence configuration.
Fello
Custom Contact Property (Fello-specific)
HubSpot
Contact (custom property)
1:1Any Fello custom contact properties beyond standard fields require HubSpot custom property creation. We audit Fello's property list pre-migration, generate a HubSpot property creation checklist, and map values during the migration run. Property types (text, number, date, picklist) map to equivalent HubSpot property types.
Fello
Attachment / File (on Contact or Deal)
HubSpot
HubSpot File (associated to record)
1:1Files attached to Fello contacts or deals are downloaded and re-uploaded to HubSpot Files. Files associate back to the contact or deal record via HubSpot's file attachment model. File size limits apply per HubSpot's file hosting configuration. We verify each file's integrity after upload and maintain the original file naming conventions to preserve document organization.
Fello
User / Owner
HubSpot
User
1:1Fello workspace owners and users resolve against HubSpot users by email match. Unmatched owners are flagged before migration — your team either creates HubSpot user accounts first or assigns records to a designated fallback owner. No record lands without a valid HubSpot owner assignment.

Migration approach
Audit Fello data inventory and create HubSpot property schema
Before any data moves, we run a full inventory of your Fello data: contact properties (standard and custom), company fields, deal records with pipeline and stage values, and file attachments. We compare this against HubSpot's standard property list and generate a HubSpot custom property creation checklist. Your HubSpot admin (or our team) creates the required custom properties in HubSpot — including Fello_Lead_Score__c, Source_System_ID__c, Original_Create_Date__c, and any Fello-specific custom fields — before validation runs. This step also includes setting up the HubSpot pipelines and stages that mirror your Fello deal pipeline structure.
Resolve Fello owners against HubSpot users by email
Fello workspace owners and user assignments are mapped to HubSpot user accounts by email address match. We generate a pre-migration owner resolution report: matched owners map automatically, unmatched owners are flagged for your team to either create a HubSpot user account or assign their records to a designated fallback owner. No contact, company, or deal record lands in HubSpot without a valid owner assignment. This step also includes validating HubSpot's user licensing to confirm that all migrating owners have active HubSpot seat access.
Migrate companies first, then contacts, then deals with pipeline mapping
HubSpot requires companies before contacts (via company association) and contacts before deals (via deal associations). We sequence the migration in dependency order: companies land in HubSpot first, then contacts with company links resolved, then deals with pipeline, stage, and owner assignments mapped. During this phase we apply field-level value mapping for Fello deal stages to HubSpot pipeline stages, preserve Fello's AI lead scores as custom properties, and map TCPA consent flags to HubSpot subscription statuses with detailed consent data in custom fields. Files attached to Fello records are downloaded and re-associated to the corresponding HubSpot records.
Run sample migration with field-level diff before full commit
We execute a representative sample migration — typically 200–500 records spanning contacts, companies, deals, and activity history — before the full run. The sample generates a field-level diff report comparing source values in Fello against destination values in HubSpot. You review the diff to confirm that AI lead scores landed correctly, deal stages mapped to the right HubSpot pipeline stages, TCPA consent data populated in custom properties, and owner assignments resolved as expected. Any mapping corrections are applied before the full migration run commits.
Execute full migration with delta-pickup window and rollback readiness
The full migration runs against your HubSpot portal using HubSpot's native import API. A delta-pickup window (typically 24–48 hours) captures any records created or modified in Fello during the cutover period so HubSpot reflects your final Fello state at go-live. FlitStack AI maintains a full audit log of every mapped field and record count per object. One-click rollback is available if reconciliation fails — rolling back restores HubSpot to its pre-migration state without data loss. After the delta window closes, we deliver a final reconciliation report comparing Fello record counts against HubSpot record counts for each object type.
