Enrich Company Name

Enrich Contact Company Name from Associated Company

Populate missing contact-level company name fields by copying the value from the associated company record. Uses a HubSpot workflow for ongoing enrichment and optionally an API backfill script for immediate results.

Why This Matters

Contacts missing a company name cannot be matched to ICP-classified companies, break email personalization tokens, and are invisible to company-based segmentation. In a typical neglected CRM, 40-60% of contacts may be missing this field even though the vast majority have a company association.

Prerequisites

• HubSpot Marketing Hub Professional or Sales Hub Professional (for Workflows)
• A HubSpot private app access token (HUBSPOT_ACCESS_TOKEN in .env) with contact read/write scopes (for the scripted stages)
• Python 3.10+ with uv
• Phase 1 hygiene processes completed (invalid/deleted contacts removed first)
• HubSpot auto-association enabled: Settings > Objects > Companies > "Create and associate companies with contacts" toggle must be ON. This lets HubSpot automatically create company records from email domains and associate them.

Scripts

There is no execute script: the enrichment itself runs as a HubSpot workflow (see Execute below), which handles both the backlog and future contacts.

Plan

1. Enable auto-association if not already on
2. Audit how many contacts are missing company name (before state)
3. Build a workflow that copies company name from the associated company record
4. Optionally run an API backfill script for immediate results
5. Verify enrichment results (after state)

Before

Run the before-state audit to capture the baseline: uv run skills/enrich-company-name/scripts/before.py

The core query it runs:

resp = requests.post(f"{BASE}/crm/v3/objects/contacts/search", headers=HEADERS, json={
    "filterGroups": [{"filters": [
        {"propertyName": "company", "operator": "NOT_HAS_PROPERTY"},
    ]}],
    "limit": 1,
})
print(f"Contacts missing company name: {resp.json()['total']}")

Manual approach: Go to Contacts > filter by Company name > is unknown. Record the count.

Save the count. This is your baseline for measuring success.

Execute

Method 1: HubSpot Workflow (Recommended — Handles Backlog + Future)

1. Go to Automation > Workflows > Create workflow
2. Select Contact-based > Blank workflow
3. Name: AUTO-ENRICH: Copy Company Name from Association

Enrollment trigger:

• Contact property > Company name > is unknown

Re-enrollment:

• Enable re-enrollment when associated company changes. This is the safety net: if an association forms after the workflow already ran, the contact gets re-enrolled.

Action 1: Delay 10 minutes

• This delay is critical. When a new contact enters HubSpot, the auto-association engine needs time to parse the email domain, find or create a matching company, and create the association. Without this delay, the workflow checks for an association before one exists.

Action 2: If/then branch

• Condition: Associated company > Company name (or Name) > is known
• YES branch: Add a Copy property action:
  • Copy FROM: Company > Name
  • Copy TO: Contact > Company name
• NO branch: Leave empty (contact exits). These are typically contacts with personal email addresses (gmail, yahoo, etc.) where no company can be determined.

Activate:

• Click Review > Turn on
• When prompted, select Yes, enroll existing contacts. This enrolls the entire backlog.

Method 2: API Backfill Script (Optional — Immediate Results)

Use this if you need the data populated immediately rather than waiting for workflow processing.

# Pattern: fetch contacts missing company name,
# look up their associated company, copy the name.
# 1. POST /crm/v3/objects/contacts/search  (company NOT_HAS_PROPERTY)
# 2. POST /crm/v4/associations/contacts/companies/batch/read  (get associations)
# 3. POST /crm/v3/objects/companies/batch/read  (fetch company names)
# 4. POST /crm/v3/objects/contacts/batch/update  (write the contact's company property)

Key API notes:

• Use the Search API to find contacts where company NOT_HAS_PROPERTY
• Search API caps at 10,000 results. Segment by createdate ranges if needed.
• Use Associations API v4 to get contact-to-company associations
• Batch update contacts via POST /crm/v3/objects/contacts/batch/update (100 per call)
• Respect rate limits: 100 requests per 10 seconds

Why Do Both?

• The workflow handles both backlog (enrolled on activation) AND future contacts automatically. It is the long-term solution.
• The API backfill provides immediate results if you cannot wait for workflow processing (which may take hours for large databases).
• If you only do the workflow, that is perfectly fine. It will process the backlog since existing contacts meeting the trigger criteria get enrolled on activation.

After

Wait 1-2 hours after activating the workflow (longer for very large databases), then verify: uv run skills/enrich-company-name/scripts/after.py (re-runs the before-state query and compares against the baseline).

Verification checklist:

1. The "missing company name" count should have dropped dramatically (typically from 40-60% to under 10%)
2. Remaining contacts without company names should primarily be those with personal email addresses (gmail.com, yahoo.com, etc.)
3. Spot-check 10-20 contacts to confirm the company name matches their associated company record
4. Check workflow history for errors:
   • Property type mismatch (copying to wrong field type)
   • Multiple associated companies (HubSpot uses the primary company)
5. Verify the workflow continues processing new contacts by checking for recent enrollments

Rollback

• Turn off the workflow to stop further enrichment (Automation > Workflows > toggle off).
• The workflow only fills empty fields, so there is nothing to "restore" — but if bad values were copied (e.g., from wrong primary associations), filter contacts by the workflow's enrollment history and clear the company property, or restore values from each contact's property history.

Key Technical Learnings

• The 10-minute delay is a balance. Auto-association typically completes in a few minutes, but 10 minutes provides a comfortable buffer. If many contacts go down the NO branch and later get associations, increase to 15-20 minutes.
• Re-enrollment is the safety net. Even if the delay is not long enough, re-enrollment on "associated company changes" catches late associations. The delay handles the common case; re-enrollment handles edge cases.
• Primary company wins. If a contact is associated with multiple companies, HubSpot copies from the primary associated company. Verify primary associations are correct for key contacts.
• This workflow does NOT overwrite existing values. The enrollment trigger requires "Company name is unknown", so contacts with an existing company name are never touched.
• Property type matters. Contact "Company name" is a single-line text field by default. If someone changed it to a dropdown, the copy action may fail. Check in Settings > Properties before running.
• Personal email domains exit on the NO branch. Contacts with gmail.com, yahoo.com, hotmail.com, outlook.com, etc. will not get enriched. This is expected. They need manual enrichment or an external provider — see /waterfall-enrich-contacts for the provider-agnostic path.
• Company name is a prerequisite for ICP Tier classification. Run this enrichment before creating ICP Tier workflows.
• Schedule the "after" verification script. Workflow processing for large databases takes time. Do not check results immediately — schedule the verification for 2-4 hours after activation.
