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

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

Pros and cons

Factors.ai

Lite $199/mo after a no-card trial

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
