Overview
Migrating from Lead Guerrilla to Monday.com CRM is a structural migration that spans two fundamentally different design philosophies. Lead Guerrilla is a marketing automation platform tightly coupled to 1CRM, storing Contacts, Companies, Campaigns, Segments, and lead scoring behavior as discrete objects. Monday.com CRM is a board-based work management system where CRM data lives inside customizable boards with columns and items. We extract records from Lead Guerrilla through staged CSV exports and manual admin-UI operations (no documented API exists), then transform and insert them into Monday.com CRM's Leads board, Accounts board, and custom boards built to match the customer's data model. Lead scoring values, campaign enrollment history, tag assignments, and activity timestamps migrate as custom column values. Marketing automation rules, landing page logic, and web form configurations do not migrate; we deliver a reimplementation playbook for the customer's team to rebuild these in Monday's Automation and Integrations layers. The 1CRM coupling creates cross-reference risks that we audit and resolve during scoping.

Object mapping
Each row shows how a Lead Guerrilla object lands in monday CRM, 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
monday CRM
Leads board (item)
1:1Lead Guerrilla Contacts map to individual Items on Monday.com CRM's Leads board. Each contact's name, email, phone, address, and custom properties become column values in the corresponding Monday board. Lead scoring values from Lead Guerrilla transfer as a custom Number column (Lead Score) on the Leads board. Email opt-in status maps to a custom Checkbox or Dropdown column. The primary lookup key is the contact email address for deduplication during import.
Lead Guerrilla
Company
monday CRM
Accounts board (item)
1:1Lead Guerrilla Companies map to Items on a Monday.com CRM Accounts board. Company name, domain, industry, employee count, and address fields map to custom columns we configure on the Accounts board. The Contact-to-Company linkage from Lead Guerrilla is preserved by adding a Connected Boards or Link column on the Leads board pointing back to the parent Account item, maintaining the relationship without a foreign-key constraint.
Lead Guerrilla
Campaign
monday CRM
Campaign board (item)
1:1Lead Guerrilla multi-channel campaigns (email, SMS, Twitter, web notifications) map to Items on a dedicated Campaign board in Monday.com CRM. Campaign name, channel assignments, timing rules, and enrollment triggers are cataloged as column values and notes on each campaign item. Note that Monday.com CRM does not have a native campaign execution engine; the customer's team uses the campaign configuration as a reference record for rebuilding campaign logic in Monday's Automation layer post-migration.
Lead Guerrilla
Segment
monday CRM
Tag-based group or custom board
lossyLead Guerrilla Segments (dynamic groups based on form source, behavior, or demographic criteria) are exported as filter definitions with member counts. In Monday.com CRM, we map segment membership to Tags applied to the corresponding Lead items, or to a separate Segments board with items linked to the Leads they contain. The customer chooses the segmentation strategy during scoping based on how they plan to use Monday's filter and group-by views.
Lead Guerrilla
Lead Scoring
monday CRM
Lead Score column (Number type)
1:1Lead Guerrilla's numeric lead score per contact (calculated from website behavior, form submissions, and campaign interactions) transfers as a custom Number column on the Leads board. The scoring model itself (point values per action, score thresholds) is cataloged in the reimplementation playbook so the customer's team can configure automation rules in Monday.com CRM to recalculate scores from scratch if needed. Historical scores are preserved as a static column value at migration time.
Lead Guerrilla
Activity
monday CRM
Updates and Activity Log columns
1:manyLead Guerrilla Activities (email opens, page visits, form submissions, SMS sends, tweet engagement) with timestamps merge into the Updates feed on each Lead or Account item as chronological note entries. High-volume activity records (thousands per contact) are summarized and deduplicated by event type and date to avoid creating thousands of individual update entries that degrade Monday board performance. Activity timestamps are preserved in the update text.
Lead Guerrilla
Tag
monday CRM
Tags column
1:1Lead Guerrilla tags applied to Contacts and Companies transfer as Monday.com Tags on the corresponding items. Tag naming conventions are preserved exactly as-is to maintain segmentation continuity. Tags serve as the primary segmentation mechanism in Monday.com CRM, enabling the customer's team to filter Leads and Accounts by the tags carried over from Lead Guerrilla without rebuilding tag names manually.
Lead Guerrilla
User/Owner
monday CRM
Person column or assignee
1:1Lead Guerrilla user accounts (campaign owners and assignment recipients) are exported by name and email. In Monday.com CRM, these users are mapped to the Person column on Leads and Accounts boards if they are active Monday.com workspace members. If a Lead Guerrilla owner has no Monday.com account, we hold the assignment in a reconciliation queue for the customer's admin to provision the user before record import.

Pair-specific challenges
Migration approach
Discovery and Lead Guerrilla admin extraction
We conduct a scoping session to inventory all Lead Guerrilla objects in use: Contact count, Company count, active Campaigns, Segments, tag taxonomy, activity history volume, and lead score definitions. We work with the customer's Lead Guerrilla admin to coordinate staged CSV exports for Contacts and Companies, manual extraction of campaign and segment configuration, and screenshot documentation of active automation rules. This phase produces the extraction package that all subsequent work depends on.
Monday.com CRM board design workshop
We run a board-design workshop with the customer's team to define the Leads board, Accounts board, and any custom boards required for Campaigns or Segments. The workshop covers column selection and data types, tag taxonomy (aligned with Lead Guerrilla's existing tags), lead score column configuration, and person-assignment columns with owner resolution. Board design is locked in a shared document before any schema is built in Monday.com. This step is a prerequisite for migration and cannot be skipped.
Sandbox migration and reconciliation
We run a full migration into a Monday.com CRM sandbox workspace (or a parallel workspace the customer creates for testing) using the extracted Lead Guerrilla data. The customer reconciles record counts, spot-checks 25-50 records against the Lead Guerrilla source, and validates that board-column mappings hold for edge cases such as international addresses, multi-value tags, and contacts with no assigned owner. Schema corrections happen in sandbox, not in production.
Owner reconciliation and user provisioning
We extract every distinct Lead Guerrilla user referenced on Contacts, Companies, and Campaigns and match by email against the Monday.com CRM workspace members. Any Lead Guerrilla owner without a matching Monday.com user is placed in a reconciliation queue for the customer's admin to provision. Owner assignments on imported items cannot be resolved without a valid Monday.com user, so this step gates the production migration.
Production migration in dependency order
We run production migration in this order: Accounts (from Lead Guerrilla Companies), Leads (from Lead Guerrilla Contacts with tag assignments, lead score values, and email opt-in status), tag taxonomy applied across all items, campaign reference records, activity summaries as update entries on the relevant Lead and Account items. We disable active automations before import and re-enable them after cutover. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation rebuild handoff
We freeze Lead Guerrilla writes during cutover, run a final delta migration of any records modified during the migration window, then designate Monday.com CRM as the system of record. We deliver the automation rebuild playbook covering every active Lead Guerrilla workflow, the landing page and form inventory for the customer's rebuild team, and the activity summary log. We support a one-week hypercare window for reconciliation issues. We do not rebuild Lead Guerrilla automations in Monday.com's Automation layer; that work is documented for the customer's team to execute.
