A five-tier waterfall — free signals first, paid vendors only when nothing cheaper resolves. The cascade exits on the first verified match.

The cascade

Five tiers.
Exit on match.

Free signals first. SMTP next. LinkedIn router after that. Paid finders only if nothing cheaper resolves. Verification last. The cascade stops descending the moment any tier returns a verified match.

Free signals

20+ public-records modules: permutations, IRS 990, CommonCrawl, MX fingerprint, GitHub, HIBP, NPPES, ORCID, arXiv, certificate transparency, ATS job boards, archive.org. An LLM fuses them into a ranked candidate.

Self-hosted SMTP

MX fingerprinting detects Proofpoint, Mimecast, Barracuda, and Cisco gateways. A catch-all probe walks the MX priority chain to bypass catch-all domains.

LinkedIn router

Multi-source router across six providers — cache, scrape, and archive. An LLM ranker picks the best result.

Paid finders

Premium enrichment vendors. Only fired when nothing cheaper resolves.

Ten-layer verification

Tiered verifier with LLM trust-score gate that cuts paid-verifier spend before any paid call. Specialized healthcare scorer.

Principles

Three rules.

Each one cuts cost on a different axis. Together they make the system get cheaper as you use it.

01

Free First

Public-records signals run before any paid call. An LLM fuses them into a ranked candidate. If it resolves, the cascade exits.

02

Cache Forever

Once a domain pattern is learned, the expensive tiers are skipped on every future request. The system gets cheaper as it gets used.

03

Risk Labeled

Every source carries a T0–T3 compliance class. Customers cap the ceiling. GDPR posture without code changes.

Domain memory was the unlock. Our second pass over the same domain is effectively free. Nobody else does this.
