RB2B Review: Is It Worth It for Tech Startups?

Website visitor identification tool that pushes person-level data to Slack in real time.

Our Take

RB2B is one of the most interesting tools to emerge in the past two years. The concept is powerful: instead of showing company-level data (like 6sense or Clearbit Reveal), RB2B identifies the actual person visiting your website and sends their LinkedIn profile directly to Slack. Your SDR gets an alert: "Jane Smith, VP of Engineering at Acme Corp just visited your pricing page."

In practice, the workflow looks like this: visitor identified → Slack alert to SDR → SDR views LinkedIn → sends personalized connection request referencing the page they visited → 3x normal acceptance rate because the timing is right. We've seen clients convert 5–8% of RB2B-identified visitors into pipeline conversations, which at any reasonable ACV is exceptional ROI.

The limitation is match rate. RB2B identifies roughly 30–40% of US visitors — the rest are anonymous or on VPNs. But at $150/month for a starter plan, even identifying 50 high-intent visitors and converting 3 into pipeline opportunities can pay for a year of the tool.

What Works

  • Person-level identification (not just company) with LinkedIn profile
  • Real-time Slack alerts — perfect for hot handoff to sales
  • Free plan for up to 200 identifications/month
  • No cookies or forms required from visitor
  • Simple implementation (one script)

Watch Out For

  • US traffic only for person-level identification
  • $150–$500/month for full data access
  • Match rates of 30–40% of visitors — miss a majority
  • Requires follow-up workflow to convert identified visitors into pipeline
  • Can't identify corporate VPNs or mobile traffic

Best For

B2B startups with meaningful website traffic (2,000+ monthly US visitors) who want to convert anonymous intent into outbound pipeline.
