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.
