Knock2 vs Leadfeeder

Knock2 identifies website visitors, builds profiles, scores visits, and routes leads into sales workflows. It identifies companies globally, while names and contact details for individuals are available only for US traffic. Profiles can include a visitor’s name, title, verified work email, phone, company, and pages viewed. Its AI lead-scoring agent evaluates visits against a team’s description of its ideal customer profile. Workflows can alert sales representatives in Slack, create CRM records, and enroll visitors in sales sequences. Listed connections include HubSpot, Salesforce, Attio, Slack, Microsoft Teams, Apollo, Outreach, Instantly, Smartlead, Zapier, and webhooks. MCP and REST API access also connects with AI tools such as Claude, Claude Code, Cursor, and ChatGPT. Knock2 is available on web and through an API. Paid plans start at $199 a month, billed monthly, for up to 600 contacts per month and 3,600 credits. A 7-day trial is available; there is no free plan. Monthly credits reset each billing month, and exceeding an allocation requires upgrading or waiting for the reset.

Leadfeeder identifies companies visiting a business website and shows what they view and when to follow up. Its Web Visitors Tracker uses a JavaScript script placed on the site to identify visits. The product also offers company search, account lists, buying intent signals, workflows and AI features, alongside people search, phone numbers and an email finder. Native CRM integrations support two-way sync with HubSpot, Salesforce and Pipedrive; other connections include Slack, Google Ads, analytics tools and more than 5,000 apps through Zapier. The Connect Browser Extension provides company and contact details in Google Chrome and Microsoft Edge. Leadfeeder describes its audience as B2B revenue teams working to identify engaged companies and develop qualified pipeline. The free Lite plan is free, with unlimited users, 7 days of visitor history and up to 100 identified companies per month. Paid plans start at €79 a month billed annually, and a 14-day trial is listed. Leadfeeder says its infrastructure is hosted on AWS within the EU/EEA and customer data is encrypted in transit and at rest.
