Knock AI vs Clearbit (2026): Full Comparison, Pricing, Features & Key Differences
Clearbit provides high-quality B2B data, enriches CRM records, shortens forms, and identifies companies visiting your website through IP intelligence. But Clearbit enriches from a static database, not from the buyer’s real-time behavior. It does not identify individuals across channels, detect live intent, or activate conversations when interest is highest.
Knock AI identifies real people across every channel, Slack, LinkedIn, WhatsApp, email, G2, product usage, events, QR, AI search, communities, socials, reviews, marketplace, docs and offline events, and your website. It enriches them in real time with identity + firmographic + intent signals, analyzes readiness, engages through an AI SDR, and books meetings instantly while the buyer is still active.
Clearbit helps you understand who is in your audience.
Knock AI helps you engage who is ready right now.
This comparison shows which platform actually converts modern, intent-driven buyer behavior into a pipeline.
