RB2B

RB2B

Free person-level website visitor identification (US)

Intent Signals

Overview

RB2B identifies individual people visiting your website — US-focused — and pushes their profiles to Slack in real time, so reps can act on intent instantly. Its edge is a genuinely free person-level tier and a product-led, Slack-native workflow that made it a community favorite. The trade-offs are scope: it's US-only, reviewers flag filtering and data-accuracy gaps, and it's an identification signal, not a database or a sequencer — pair it with one to act.

Who it's for

  • →Founders and SMB teams wanting free US visitor identification
  • →Sales teams that live in Slack and want real-time intent
  • →PLG motions acting on individual visitor signals

Not for

Capabilities

  • Person-level US visitor identification
  • Real-time Slack push
  • LinkedIn + work email on identified visitors
  • Filtering & ICP rules

Our advice

RB2B is an easy yes to test because the person-level tier is free and lands in Slack where reps already are. Keep expectations scoped: US-only, signal not database, and tighten the ICP filters or the Slack channel turns into noise.

The honest take

Where it breaks

Outside the US, where coverage drops, and when treated as more than a signal — filtering and data-accuracy gaps show up, and it doesn't store data or send outreach.

The verdict

The fastest free way to put person-level US visitor intent into Slack. Pair it with enrichment and a sequencer to act — and reach for Leadfeeder if your buyers are in the EU.
