Website visitor identification software that reveals the buyer.

Software that turns an anonymous session into a company, and on US traffic into a person your team can contact. Knock2 identifies 62% of US engaged sessions at the person level and 93% of engaged sessions at the account level. Plans start at $199 a month. The side-by-side with RB2B, Warmly, Leadfeeder, Snitcher, Vector, Lead Forensics and Leadinfo is best website visitor identification software.

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.

IP address alone resolves a corporate network, not a visitor on home WiFi, mobile or a VPN. Knock2 also uses device-level signals for more precise matching.

Account-level identification tells you which company a visitor is from. It's useful for account-based marketing, territory routing, and understanding which target accounts are actively researching you. 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.

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.

Person-level identification, with names, emails and contact details, is limited to US traffic by design. Account-level identification works globally. This is how Knock2 stays compliant with GDPR, CCPA and the ePrivacy Directive in Europe. You won't see individual European or Asian visitors' personal details, but you will see which companies are visiting.

Plans start at $199/month (Startup) and scale with included credits. Identifying an account costs 1 credit, identifying a person costs 6 credits, and prospecting additional contacts at an account costs 2 credits. Every plan includes a 7-day free trial.
