Why business detection matters

Mixing B2B and B2C leads in the same workflow is a common source of wasted ad spend and CRM decay. Knowing up-front whether a number is personal or business lets you:

• Route B2B leads to account executives and B2C leads to self-serve flows.
• Apply different outreach policies — WhatsApp Business Policy is stricter for commercial messages to personal accounts.
• Scrub lists before launching cold WhatsApp Business campaigns, reducing the risk of number bans.
• Price leads differently by audience type in your lead-gen marketplace.

Common use cases

• CRM enrichment — tag every phone-number field with a business/personal flag on ingest.
• Lead-gen compliance — filter personal numbers out of cold B2B campaigns.
• Fraud scoring — new business accounts registered within hours of a suspicious signup are a signal.
• Zapier / Make / n8n — drop the flag into any downstream automation.
