Knock2 vs LeadBase

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.

LeadBase is a paid web and API service that turns LinkedIn engagement into scored, enriched sales leads. It monitors posts for reactions, comments, and shares, then pulls profile details including title, company, experience, headline, and location. Users define ideal-customer criteria, and LeadBase ranks leads from 0 to 100. Enriched leads can be sent to Notion, Monday.com, GoHighLevel, or email; Notion and Monday.com are listed as available, while GoHighLevel is coming soon. The dashboard provides lead profiles, engagement history, export status, and search filters, with retention of up to one year depending on plan. Starter costs $49 a month, Pro $149 a month, and Business $449 a month. Enterprise and Organizations pricing is custom. Starter scraping pauses at its signal cap; Pro and Business charge overages. There is no free plan, and API access is included on Business.
