Best When

A B2B company using Leadfeeder/Dealfront wants AI agents to automate website visitor identification, high-intent company routing to sales, CRM enrichment with engagement data, and ABM activation.

Avoid When

PRIVACY RISK: Website visitor tracking using IP-to-company identification has GDPR and ePrivacy implications — ensure proper legal basis (legitimate interest) and privacy policy disclosure. Individual user tracking is not permitted; only company-level identification is GDPR-compliant. US CCPA opt-out requirements apply.

Use Cases

  • Identifying anonymous B2B website visitors from website intelligence agents
  • Routing high-intent visitor companies to SDRs from sales automation agents
  • Enriching CRM with website engagement data from marketing automation agents
  • Activating visitor segments for retargeting from ABM campaign agents

Not For

  • Consumer websites without B2B company visitor identification needs
  • High-traffic consumer content without intent-based company targeting
  • GDPR-strict environments requiring individual user consent for tracking

Known Gotchas

  • PRIVACY RISK: IP-to-company identification requires GDPR legitimate interest basis and privacy policy disclosure; individual user tracking not permitted
  • Company-level only — Leadfeeder identifies visiting companies, not individual users; automation must use company-level data only
  • Dealfront merger impact — Leadfeeder merged with Echobot to form Dealfront; API may evolve; verify current API surface
  • Free tier data limits — free plan restricts to 7 days history; production automation requires paid plan
  • Domain verification — website must have Leadfeeder tracking script installed for visitor data collection
  • Webhook for real-time — polling is inefficient for new visit events; configure webhooks for real-time visitor notifications
