Where they pull apart

RB2B

Stands out: US person-level visitor ID with a forever-free company-level rung, with HubSpot, Salesforce, Slack, Clay, and Zapier named.

Watch out: Person-level starts at Starter $79. Pro is $149 and Pro+ $199. This is US-centric; do not expect EU personal identification.

Not the right fit for

EU GDPR-first visitor ID
Teams that only need account-level (Albacross/Snitcher)
People who need a sequencer

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

RB2B

Forever-free company-level plus $79 person-level Starter
7-day trial
HubSpot, Salesforce, Slack, Clay, Zapier named

US person-level, not a global GDPR product
Not a sequencer
Paid rungs escalate quickly

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
