01 · Match rate
More people from the same traffic.
Knock2 identifies 62% of US visitors to the person, on every plan. RB2B’s own pricing page lists 15-20% on Starter and Pro, and 35-45% on Pro+.
Pro+ costs $199 a month. So does Knock2’s Startup plan.
“Compared to RB2B or other platforms, Knock2 identifies way more people. It's more accurate, faster to set up, and plugs right into the tools I already use.”
02 · Buying committee
The whole committee, not one visitor.
RB2B shows you the person who visited. Knock2 also finds the rest of the buying committee at that account, with verified emails.
Reps reach everyone who decides, not just the one person who happened to read your pricing page.
03 · Lead scoring
Scored before anyone looks.
Describe your ideal customer in a sentence. Every visitor and account gets a score and the reason for it, so reps start with the best fit instead of scrolling a feed.
04 · Delivery
Routed, not just alerted.
Send each buyer where they belong by score, pages read and company: HubSpot or Salesforce with an owner, Slack, your sequencer, Clay or your own webhook, all from one visit.
Or ask Claude about your visitors and act on them through the Knock2 MCP server.

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's pricing page lists 15-20% contact-level coverage on its Starter and Pro plans and 35-45% on Pro+.
How is Knock2 different from RB2B specifically?
Three main differences. First, match rate: Knock2 identifies 62% of US visitors at the person level on every plan. RB2B's pricing page lists 15-20% on Starter and Pro and 35-45% on Pro+.
Second, reach beyond the visitor: Knock2 finds the rest of the buying committee at the account and scores every visitor against an ideal customer profile you describe in plain English.
Third, delivery: Knock2 routes each buyer by score, pages and company to HubSpot, Salesforce, Slack, Apollo, Outreach, Lemlist, Instantly, Smartlead, HeyReach, Clay or a webhook, and works with Claude through its MCP server.
How does Knock2 identify visitors on my site?
You add a small script to your site. When someone visits, Knock2 matches that visit against licensed identity data to resolve the person and the company behind it. You get name, title and business contact details.
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 is built on the same class of identity and analytics technology already running on most B2B websites.
Person-level identification runs on US traffic only, by design. Everywhere else, Knock2 returns company-level information only. That is how it stays within GDPR, CCPA and ePrivacy expectations. The identity data itself is licensed from established data providers.
How does pricing work?
Plans start at $199/month (Startup) and scale with included credits: Growth ($499), Growth Plus ($749) and Scale ($999). Every plan identifies visitors at the same match rate, and every plan includes a 7-day free trial. See pricing.
