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

Untitled AI

Stands out: Every plan includes the full platform. You pay for monthly unique visitors, not feature gates.

Watch out: Published prices are annual. Starter covers 25,000 unique monthly visitors. CTV, programmatic, and direct mail media are billed on top.

Not the right fit for

Teams that need month-to-month published pricing
B2B sales teams that only want form-fill visitor ID
