Top 3 reasons to switch from RB2B

Knock2 customers consistently report the following as top reasons they switched from RB2B.

01 Reach the person, not the logo
50%
more person-level identifications from the same traffic

A better pixel. More people identified. Same traffic.

RB2B self-reports a 40–45% person-level match rate. Knock2's measured rate is 62% — about 50% more identified visitors from the same US traffic. Same pixel install, meaningfully more pipeline.

Knock262% person-level match rate, measured
RB2B40–45% person-level, per their own published docs
02 Multi-thread from day one
4–6x
buyers surfaced per identified account

One visitor isn't the whole committee.

RB2B shows you the one person who hit your site. Knock2 identifies that person — and auto-surfaces the rest of the buying committee at the same account, so reps multi-thread from the first touch.

03 Ship to sequence, not an inbox

native sequence + CRM integrations, no Zapier

Identification isn't revenue. Activation is.

RB2B pushes a LinkedIn profile to Slack — you still need Clay, Apollo, Lemlist, and a validator to turn it into pipeline. Knock2 does the identification and the activation: workflows, email validation, re-enrichment, committee discovery, CRM sync — all in one system.

FAQ

Frequently asked questions

How is the 93% match rate measured?

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.

How is Knock2 different from RB2B specifically?

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.

How does Knock2 identify visitors on my site?

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.

What's the difference between account-level and person-level identification?

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.

Will this work with my CRM and sales tools?

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.

Is this actually legal?

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.

How does pricing work?

Plans start at $199/month (Startup) and scale with included credits. Most teams land on Growth ($499) or Scale ($999) once they see their actual traffic volume. Every plan includes a 7-day free trial.
