Overview
Lead Guerrilla functions primarily as a marketing automation layer over a CRM backend — its core objects are contacts, companies, campaigns, segments, and multi-channel campaign actions (email, SMS, Twitter, web notifications). It stores lead-scoring values, campaign enrollment history, and segment membership as primary data. HubSpot CRM natively models contacts with lifecycle_stage, companies as separate account records, deals with pipeline-and-stage tracking, and uses workflows and lists for automation logic. These models overlap at the contact and company level but diverge significantly on automation architecture, lead scoring, and multi-channel campaign handling. FlitStack AI extracts your Lead Guerrilla data via its API, maps contacts to HubSpot contacts (preserving email, phone, jobtitle, address fields), maps Lead Guerrilla companies to HubSpot companies, translates campaign enrollment records into HubSpot workflow enrollments or association properties, and moves lead-score values into HubSpot custom properties. Segments that define audience filters become HubSpot lists. Multi-channel campaign actions (SMS, Twitter, web notification steps) cannot migrate as functional workflows — HubSpot's email sequences and SMS tools require separate configuration. Owner and user resolution happens by email match against HubSpot users before migration commits.
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 Lead Guerrilla 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.
Lead Guerrilla
Contact
HubSpot
Contact
1:1Lead Guerrilla contacts map 1:1 to HubSpot contacts. All standard properties (name, email, phone, address) migrate directly. The contact's original create date is preserved as a custom datetime field since HubSpot's Createdate is set at import time. Custom fields unique to your Lead Guerrilla setup are also migrated as additional properties, provided they are pre-created in HubSpot.
Lead Guerrilla
Company
HubSpot
Company
1:1Lead Guerrilla company records map to HubSpot companies. Domain, industry, employee count, and annual revenue fields migrate to their HubSpot equivalents. Multi-company associations per contact collapse to HubSpot's primary-company model. If your Lead Guerrilla data includes additional company-level custom fields, those are exported and recreated as custom properties in HubSpot prior to the migration.
Lead Guerrilla
Campaign
HubSpot
Workflow + List
1:1Lead Guerrilla campaigns do not have a direct HubSpot equivalent because HubSpot separates email sequences, SMS, and social into distinct tools. We export campaign metadata (name, description, create date) as a HubSpot custom object record and map campaign enrollment to a HubSpot list membership or workflow-enrollment custom property.
Lead Guerrilla
Segment
HubSpot
List (static or dynamic)
1:1Lead Guerrilla segments define contact-filter logic for audience targeting. We translate segment filter criteria into HubSpot list-builder criteria. Dynamic segments become HubSpot dynamic lists; static segments become HubSpot static lists. Segment membership history is preserved as a property on each contact.
Lead Guerrilla
Lead Score
HubSpot
Custom property (numeric)
1:1HubSpot has no native lead-score field. We create a custom numeric property (Lead_Score__c equivalent via HubSpot property name) and migrate the Lead Guerrilla score value per contact. HubSpot's own predictive lead scoring tool must be configured separately post-migration. Your team should evaluate whether to continue using the legacy scores or adopt HubSpot's predictive model.
Lead Guerrilla
Campaign Enrollment Record
HubSpot
Custom property + List membership
many:1A Lead Guerrilla contact's enrollment in a campaign is stored as a record linking contact ID to campaign ID. We merge these into a HubSpot list membership for the corresponding campaign-list and write the enrollment date as a custom datetime property on the contact.
Lead Guerrilla
Email send / open / click record
HubSpot
Email activity (logged via HubSpot activity)
1:1Lead Guerrilla tracks email send, open, and click events as activity records. These are logged to HubSpot's contact timeline as engagement events. Historical open and click counts migrate as custom number properties if HubSpot's native engagement tracking cannot backfill them.
Lead Guerrilla
SMS send record
HubSpot
Custom property (SMS_history__c)
1:1HubSpot SMS history is tracked within the HubSpot SMS tool and does not have a portable API export. We preserve SMS send records as a JSON-formatted custom property on the contact for reference. The actual SMS threads must be re-established in HubSpot's SMS tool post-migration.
Lead Guerrilla
Twitter / social engagement record
HubSpot
Custom property (Social_Engagement__c)
1:1Lead Guerrilla's social-channel campaign actions (Twitter mentions, web notifications) have no HubSpot equivalent. Social engagement records from Lead Guerrilla are preserved as custom properties on the contact record. HubSpot social inbox handles future social interactions separately. If you rely on historical Twitter engagement metrics for reporting, those values remain accessible through the custom property but will not trigger HubSpot workflows.
Lead Guerrilla
Landing Page submission
HubSpot
Form submission (via HubSpot form)
1:1Lead Guerrilla landing page submissions map to HubSpot form submissions. Each submission is logged on the contact timeline with the original submission date and UTM source fields preserved. Landing page configuration is exported as a rebuild reference for HubSpot native forms.
Lead Guerrilla
Custom Object (if applicable)
HubSpot
Custom Object
1:1Lead Guerrilla allows custom data objects beyond contacts and companies. These map 1:1 to HubSpot custom objects. All custom field definitions are exported and recreated in HubSpot before data migration runs. N:N associations between custom objects require HubSpot junction objects.
Lead Guerrilla
Owner / User
HubSpot
User
1:1Lead Guerrilla owner IDs are resolved by email match against HubSpot users. Unmatched owners are flagged before migration — teams either invite them to HubSpot first or assign their records to a designated fallback owner. This prevents orphan records in HubSpot.

Migration approach
Extract Lead Guerrilla data via API
FlitStack connects to Lead Guerrilla's API using scoped read access. We extract all contacts, companies, campaign enrollment records, segment membership data, lead score values, landing page submission history, and any custom objects. Data is paginated in batches to respect API rate limits. The export includes original create timestamps, last-modified timestamps, owner IDs, and all custom field values. This step runs read-only — your Lead Guerrilla account remains fully operational throughout.
Map Lead Guerrilla data model to HubSpot schema
We translate Lead Guerrilla contacts to HubSpot contacts, companies to HubSpot companies, and campaign enrollment records to a combination of HubSpot list membership and custom properties on each contact. Lead score values are flagged for custom property creation in HubSpot. Segment definitions are exported as reference data for HubSpot list-builder translation. All field names are mapped value-by-value, with pick-list value mapping applied for industry and country fields. Custom field definitions are identified and flagged for HubSpot pre-creation before data import.
Create HubSpot custom properties and list structure
Before importing data, our team creates all required custom properties in HubSpot: lead_score__c, original_create_date__c, source_system_id__c, segment_names__c, campaign_lists__c, and others identified during the mapping phase. Lead Guerrilla segments are documented as a translation guide for your HubSpot admin to recreate as HubSpot lists. This step requires HubSpot admin credentials with permission to create custom properties. We deliver a property creation checklist and validate that all custom fields are available in HubSpot before the import begins.
Run sample migration with field-level validation
A representative slice of records — typically 200–500 contacts spanning different segments, companies, and campaign enrollment histories — migrates first. We generate a field-level diff showing source values against HubSpot destination values so you can verify lead score mapping, lifecycle stage initialization, company association resolution, and segment property population. You review the sample before the full migration commits. This step surfaces mapping gaps early so they can be corrected without reprocessing the entire dataset.
Execute full migration with delta-pickup window
The full dataset migrates into HubSpot in sequenced batches: companies first, then contacts, then custom objects and activity history. A delta-pickup window of 24–48 hours captures any records created or modified in Lead Guerrilla during the cutover window. All operations are logged in an audit trail. If reconciliation reveals missing or mismatched records, one-click rollback is available. After final validation, your team transitions to HubSpot as the system of record.
