Identify 50% more buyers than RB2B.

The 93%* figure refers to account-level identification on engaged sessions (Google Analytics defines an engaged session as 10 seconds or more, or 2+ pageviews). The 62%* figure is for person-level identification on US traffic, measured the same way. For reference, RB2B self-reports a 40 to 45% person-level match rate on the same methodology, which is about 50% less coverage from the same US traffic.

Three main differences. First, match rate: Knock2 identifies 62%* of US visitors at the person level vs RB2B's self-reported 40 to 45%, which is roughly 50% more identified contacts from the same traffic.

Second, coverage: Knock2 provides both account-level (global) and person-level (US), while RB2B is US-only person-level. If your pipeline includes European or Asian traffic, RB2B gives you nothing for those visits.

Third, native integrations: Knock2 includes HubSpot, Salesforce, Apollo, Outreach, Lemlist, and Slack built in, plus buying committee expansion, last-mile email validation, and contact re-enrichment. RB2B's workflow layer is thinner.

Knock2 uses device fingerprinting combined with an identity graph built from consented publisher login data. When someone logs into a major publisher site, their identity is tied to their device. When that same device later visits your site, our pixel matches it back to the person. It's the same underlying technology that powers retargeting pixels from Meta, Google, and LinkedIn.

Account-level identification tells you which company a visitor is from. Person-level identification tells you exactly who the individual is: name, title, work email, phone, and LinkedIn profile. Person-level data is only available for US traffic due to privacy regulations in other regions. Most teams use both: account-level coverage for breadth, person-level for direct outreach.

Yes. Native integrations are built for HubSpot, Salesforce, Slack, Apollo, Outreach, Lemlist, Instantly, and Clay. For anything not on that list, webhooks cover Zapier, Make, n8n, and any other tool that accepts them.

Yes. Knock2 uses the same underlying technology as ad retargeting pixels from Meta, Google, and LinkedIn. Our data comes from consented publisher login co-ops, tying identity to an anonymous device fingerprint. There are no cookies involved, so cookie consent requirements don't apply. Knock2 is SOC 2 compliant.
