Where they pull apart

Factors.ai

Stands out: Visitor ID plus intent plus attribution in one GTM platform (HubSpot, Salesforce, Slack, Teams, LinkedIn named), not a $49 Snitcher clone.

Watch out: Lite is $199/mo after the trial. Basic is $6k/year. This is not a free forever product for production volume.

Not the right fit for

  • SMB teams that want $49 company ID
  • Person-level US identification (use RB2B)
  • Recruiting desks that do not run a website GTM motion

Warmly

Stands out: Live visitor alerts into Slack and CRM, with an inbound chat/autopilot upsell, not a $79 RB2B clone.

Watch out: The $10,000/year figure is the floor. Chat is $20k/year; Autopilot $30k/year. MCP and API exist; this is still a GTM platform price.

Not the right fit for

  • SMBs that want $79 person-level ID
  • Recruiting teams without a GTM motion
  • EU-only programmes that cannot deanonymize people

Pros and cons

Factors.ai

  • Lite $199/mo after a no-card trial
  • Intent plus visitor ID plus attribution
  • HubSpot, Salesforce, Slack, Teams named
  • Not $0 for production use
  • Company-level, not RB2B person-level
  • Overkill for a recruiting marketing site with no GTM team

Warmly

  • Public $10k/year floor instead of a pure quote
  • Real-time alerts, not a daily CSV
  • MCP and API
  • Five-figure floor
  • Chat and autopilot are separate $20k/$30k rungs
  • Wrong tool for a recruiting careers site with no GTM team
