Enigma and KnowFirm both publish self-serve pricing for US business data — a refreshing contrast to sales-gated KYB vendors. The differences are in the details: KnowFirm ships an MCP server so AI agents can call KYB tools directly, and publishes measured per-field fill rates on /coverage. Figures below are from Enigma's published tiers at the time of writing; the Enigma name is used nominatively only.
| KnowFirm | Enigma | |
|---|---|---|
| Pricing model | Self-serve: Free (10 credits/mo), Starter $49/mo (1,500 credits), Growth $199/mo (8,000 credits). Hard quotas, no overage. | Self-serve tiers published: Free, Pro ~$20/mo, Max ~$200/mo, plus per-match usage charges (see source; estimates). |
| Start without talking to sales | Yes — sign up and query live data on the Free plan, no credit card. | Yes — Enigma publishes a free tier and self-serve paid tiers. |
| MCP server for AI agents | Yes — a published MCP server for Claude, Cursor, VS Code and other agent clients. See /docs/mcp. | No MCP server documented at the time of writing. |
| Coverage focus | US business entities from public records with measured per-field fill rates published on /coverage. | US small-business identity, revenue and card-transaction-derived signals. |
| Data posture | Public-record & firmographic data with per-field provenance and confidence scores; documented opt-out and attribution. | Business identity and financial-activity data; see Enigma's documentation for specifics. |
| FCRA boundary | KYB only — explicitly not a consumer report (FCRA); not for credit, employment, insurance, or housing eligibility. | Positioned as business data/verification. Confirm permitted use with the vendor. |
KnowFirm returns KYB & firmographic data only — it is not a consumer report (FCRA) and must not be used for credit, employment, insurance, or housing eligibility decisions.
