| Compare | Knock AI | ZoomInfo |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | B2B teams with high-intent inbound traffic | Enterprise outbound sales teams |
| Who it's not for | Small teams . $700/mo entry is overkill | Small teams . five-figure annual commitment |
| Privacy | No known public vulnerabilities found in the sources reviewed.11 | Mature security program (bug bounty, published overview); one alleged 185M-record database sale remains unconfirmed. |
| Support quality | No support evidence in sources | No direct support evidence found |
| Public sentiment | Roundups describe Knock as a legitimate form replacement with real-time AI SDR conversations, but verbatim user reviews were scarce in our sources.³ | Sentiment splits: the data depth is praised, while price, auto-renewal, and navigation draw frequent criticism across Reddit, G2, and Trustpilot.13 |
| Biggest gotcha | Pricing appears in only one source ($700/mo); confirm current tiers with sales.² | Auto-renewal and multi-year locks are the top contract trap |
