Where they pull apart

Fibbler

Stands out: Growth at $89/mo includes HubSpot, Attio, and Pipedrive sync plus unlimited company insights for one user. Unlimited at $129/mo adds Salesforce, unlimited users, and MCP.

Watch out: Growth is one user and one LinkedIn ad account. Extra ad accounts need Agency ($159/mo, two workspaces, then $69/mo each). Google Ads attribution is a $59/account/mo add-on.

Not the right fit for

  • Demand-gen orgs that need person-level identity or multi-channel attribution out of the box
  • Solo marketers who must share one Growth login across a team (Unlimited starts at $129/mo)

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
