Questions, answered
For anyone who wants the full contact, phone number included, on any US traffic, yes.
No. RB2B delivers a name, a LinkedIn profile, and a validated business email. A phone number isn't one of its fields at any tier — phone shows up only as a channel to reach out on. KnownVisitors includes a phone number, flagged against the Do Not Call registry.
RB2B matches cookies, device IDs, and IP addresses against a publisher network, with Demandbase reverse-IP for company-level lookups. KnownVisitors is deterministic and first-party, anchored to each visitor's relationship with your own domain, so it holds up as third-party cookies disappear.
