It builds a profile for Claude AI to score, parses the resulting score and tier, then upserts the contact in HubSpot. Finally, it routes the lead by tier: hot leads create a deal and alert sales, while warm and cold leads receive appropriate email follow-up.\n\n### Setup steps\n\n- Configure the webhook URL in the inbound form so submitted lead data reaches the workflow.\n- Add HubSpot credentials/API access for property creation, contact upsert, and deal creation nodes.\n- Add Anthropic API credentials for the Claude AI lead scoring and company news/search requests.\n- Configure Gmail credentials and email templates for hot, warm, and cold lead responses.\n- Configure Slack credentials and set the sales Slack channel in the Lead Scoring Config node.\n- Review the ICP description and hot/warm score thresholds in the Lead Scoring Config node before activating.\n\n### Customization\n\nAdjust the ICP, score thresholds, HubSpot property names, lifecycle routing rules, Slack channel, and email copy to match your sales process."
