Person-level visitor ID vs. full revenue orchestration — and which motion you actually need.
Website visitor identification is one of the fastest-growing categories in GTM. RB2B pioneered the "inbound-led outbound" motion — Adam Robinson built it to solve a simple problem: you know companies visit your site, but you do not know which person is browsing. RB2B identifies the individual visitor and pushes their LinkedIn profile to Slack in real time. Warmly takes a broader approach — company and person identification, real-time chat, meeting scheduling, and revenue orchestration across the funnel. The question is whether you need a focused tool or a full platform.
Person-level identification
RB2B's core innovation is identifying the individual person visiting your site, not just the company. You see "Sarah Chen, VP of Engineering at Acme Corp, is on your pricing page right now" — with her LinkedIn profile link. This is powerful for outbound teams. Warmly also does person-level ID but bundles it with company-level identification, which gives broader coverage at the cost of less focus on the individual signal.
What happens after identification
RB2B sends a LinkedIn notification or Slack alert when a visitor is identified. What you do next is up to you — connect on LinkedIn, send a cold email, pass to your AE. The tool is intentionally simple. Warmly adds real-time chat, automated meeting scheduling, CRM enrichment, and orchestration workflows. If you want the visitor to self-serve into a meeting, Warmly handles that. If you want to control the outreach yourself, RB2B gets out of the way.
Pricing and access
RB2B has a free tier that gives you individual visitor alerts. Their paid plans add volume and integrations. Warmly is a platform play priced accordingly — expect enterprise-level pricing for the full orchestration suite. For teams testing the visitor ID concept, RB2B's free tier is the lowest-risk way to start. Warmly requires commitment.

The verdict
Start with RB2B if you want person-level visitor identification without platform complexity. The free tier lets you test the motion with zero risk. If visitor identification is already working and you want to automate the downstream workflow — chat, meeting scheduling, CRM routing — Warmly's orchestration layer adds real value. Most teams should prove the motion works with RB2B before investing in Warmly's full platform.
How does RB2B identify individual visitors?
RB2B uses reverse IP lookup combined with device-level signals and third-party identity graph data to match website visitors to individual profiles. Match rates vary — typically 10-30% of US traffic gets person-level identification. International coverage is lower.
Is website visitor identification creepy?
It uses the same data that ad platforms have been using for years — just surfaced directly to you instead of hidden behind an ad network. The data comes from public records and consent-based identity graphs. That said, how you use it matters. Reaching out with "I saw you were on our pricing page" feels invasive. Reaching out with a relevant, timely message based on the signal does not.
Do I need both RB2B and Warmly?
No — they overlap significantly on visitor identification. Pick one. RB2B if you want focused person-level ID and plan to handle outreach yourself. Warmly if you want the identification bundled with real-time engagement and orchestration.
