TL;DR
RB2B (rb2b.com) identifies anonymous US website visitors at the person level and pushes their name, LinkedIn profile, and email to Slack or your CRM within minutes — the simplest, lowest-cost way to get the visitor signal. Alternatives include Warmly and Vector (richer visitor ID and engagement), Clearbit/Breeze and Koala, and Boomerang for turning that intent into a warm introduction. RB2B gives you the signal; Boomerang gives you the warmest way in. Here's the honest landscape.
What RB2B does
RB2B's pixel identifies a large share of US traffic at the person level and routes it to Slack/CRM in real time, where you filter and act. Person-level identification is US-only (for GDPR reasons); it's a focused signal tool, not an engagement or orchestration platform.
The real alternatives
- Visitor ID + engagement — Warmly, Vector. Add intent scoring, ads, and outreach on top of identification.
- Enrichment — Clearbit/Breeze, Koala. Visitor and account data.
- Warm-intro orchestration — Boomerang. Converts the visitor signal into a relationship-led introduction.
Where Boomerang fits
RB2B answers "who's interested?" but leaves "how do I reach them well?" to you — usually a cold email or sequence. Boomerang is the orchestration layer that turns that intent into a warm path: it finds who you already know who can introduce you to the visitor's company and runs the intro. Fully complementary.
