RB2B does person level website visitor identification. It de-anonymizes the people browsing your site, matching US based visitors to a named individual with a LinkedIn profile and, on paid tiers, a business email, then pushing that signal in real time to Slack, Teams, or your CRM. You install a small pixel, connect Slack, and anonymous traffic starts showing up as named prospects with the pages they viewed. Hot Pages and ICP filters cut the noise so your reps only see visitors that fit the profile, and native integrations to HubSpot, Salesforce, and Outreach trigger the workflows downstream. In a GTM system, it sits at the inbound layer as the de-anonymization trigger. RB2B is our default for US based visitors, where it resolves traffic down to the named person, while Leadinfo carries Europe and Snitcher is the clean GA4 alternate. We run RB2B on client sites every day. Each identified visitor is a signal and we route it into Clay for enrichment and scoring against the ICP, then identify the rest of the buying committee before anyone follows up. Used that way, RB2B turns quiet traffic into warm, timely outbound, and the visitor who was an anonymous hit becomes a named account your reps can work.
