01 · No guesswork
Know what you get before you buy.
Knock2 publishes its prices and its match rates, and every plan includes visitor identification. Sign up and it runs on your site the same day.
ZoomInfo publishes no prices. Its pricing page lists website visitors on Copilot Advanced and Marketing Demand, priced by licenses and credits through sales.
“I was blown away with your tool. I hooked it up and within 45 minutes we booked a meeting.”
02 · Buying committee
The whole committee, not one visitor.
Knock2 starts from the person who visited, then finds the rest of the buying committee at that account, with verified emails, on every plan.
Reps reach everyone who decides, starting from the person who is actually reading your site.
03 · Routing
To the right rep, with the context.
Each buyer lands in Slack with the owner tagged, the pages they read and where they sit in your CRM, then goes to HubSpot, Salesforce or your sequencer.
04 · 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.

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. We publish both numbers because they answer different questions: which companies are on my site, and which individuals can I reach out to.
How is Knock2 different from ZoomInfo?
They do different jobs. ZoomInfo is a B2B data platform: reps search its database for companies and contacts. Its visitor identification, WebSights, comes with its Copilot Advanced and Marketing Demand packages, and its Buyer ID names US visitors who are in an active buying group or have engaged before. Everyone else stays at the company.
Knock2 is built only for visitor identification. It names 62%* of US engaged sessions to the person, including new buyers you have never met, and 93%* of engaged sessions to the company, then routes them to your reps. Many teams use both: ZoomInfo for cold outbound, Knock2 for the people already on the site. Knock2 publishes its prices, from $199 a month; ZoomInfo does not.
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.
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: Pro ($349), Growth ($499), Growth Plus ($749) and Scale ($999). Identifying an account costs 1 credit, identifying a person costs 6 credits, and prospecting additional contacts at an account costs 2 credits. No per-seat fees. Every plan includes a 7-day free trial. See pricing.
