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's pricing page lists 15-20% contact-level coverage on its Starter and Pro plans and 35-45% on Pro+.

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.

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.

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 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.

Plans start at $199/month (Startup) and scale with included credits: Pro ($349), 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.

It depends on what you need after the match. For person-level identification on US traffic with routing into your CRM and sequencers, Knock2 identifies the person on 62% of US engaged sessions on every plan, from $199 a month. Warmly adds AI chat on annual contracts from $10,000 a year. Vector is a full ABM platform from $36,000 a year. Snitcher, Leadfeeder, Lead Forensics and Leadinfo name the company rather than the person. The 2026 comparison lists each one with its sources.

RB2B itself has a free plan: its pricing page, checked October 8, 2026, lists 150 resolutions a month at the company level only. Knock2 has no free plan, but every plan starts with a 7-day free trial, so you can compare the people each tool finds on your own traffic before paying.
