Where they pull apart

Heartbeat

Stands out: Coverage comes from clinician license data, not LinkedIn, and each clinician's numbers are ranked by how likely they are to answer. An AI connector can email matching clinicians for every new job order in your ATS.

Watch out: No published prices, and the free test needs a call first. It is US healthcare only, and the data is not for employment screening or background checks.

Not the right fit for

  • Non-healthcare recruiting
  • Employment screening or background checks
  • Buyers who want a published self-serve price

Lead411

Stands out: Intent signals sitting alongside the dials, at a price that undercuts the enterprise data vendors.

Watch out: No MCP, and intent data is only as useful as the market you sell into.

Not the right fit for

  • LinkedIn-only browser users
  • Teams that need MCP
