Lead Forensics alternative
Lead Forensics shows the company. Knock2 names the person.
Lead Forensics tells you which company was on your pricing page. Knock2 tells you who it was: their name, title and work email.
7-day free trial. Live on your site in minutes.




01 · No guesswork
Know what you get before you buy.
Knock2 publishes its prices and its match rates: 93% of engaged sessions identified to the company, 62% of US engaged sessions to the person.
Lead Forensics publishes neither. Its price is based on your traffic, and its trial starts with a demo form or a call.
“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 a guess.
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 know who was reading and who else decides, instead of picking from a company’s list of decision makers.

03 · Delivery
Into your sequencer, not just your CRM.
Send each buyer to HubSpot or Salesforce with an owner, a Slack alert, and straight into Apollo, Outreach, Lemlist, Instantly, Smartlead or HeyReach.
Lead Forensics connects natively to CRMs and reaches other tools through Zapier. It lists no Slack or sequencer integration.

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, meaning Knock2 can tell you which company a visitor is from 93%* of the time. It's measured against "engaged sessions," which Google Analytics defines as any visit that lasts 10 seconds or longer, or includes 2 or more pageviews.
The 62%* figure is for person-level identification (name, email, title) 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 Lead Forensics?
Three main differences. First, the person: Lead Forensics identifies the company behind a visit and offers decision-maker contacts at that company. Knock2 identifies the person who visited, with name, title and email, for 62%* of US engaged sessions, as well as the company for 93%* of engaged sessions.
Second, what is published: Lead Forensics does not publish a match rate or its prices, which it says are based on your website traffic. Knock2 publishes both match rates and every plan's price.
Third, getting started: Lead Forensics' one-week trial starts from a demo form or a call. With Knock2 you sign up yourself, start a 7-day free trial and pay month-to-month from $199.
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.
Most visitor identification tools work from IP address alone. Knock2 draws on several identity sources rather than one. That is why it resolves more of your traffic: 93%* at the account level and 62%* at the person level on US traffic.
Can I reach individual people or just companies?
Both. Knock2 returns account-level data (the company) and person-level data (the specific individual, with name, title, work email, phone, and LinkedIn profile). Person-level identification is US traffic only 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. Identified visitors can be routed in real time based on lead score, pages visited, firmographics, persona match, UTMs, or any combination.
Is this actually legal? How does Knock2 identify people without them opting in?
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.
Does Knock2 work outside the US? What about GDPR?
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.
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. Every plan includes a 7-day free trial. See pricing.
