LeadGen Engine doesn’t maintain a static contact database — instead, we query licensed enrichment providers in real time when you make a request. The combined addressable universe across our integrated providers is up to ~180M+ verified business contacts in the US alone, with billions of person-records globally available on demand.
This page documents exactly which providers we use, what they cover, and how the math works.
| Provider | Capability | Addressable scope (provider-published) |
|---|---|---|
| PeopleDataLabs | Person enrichment (email + phone + employment history) | ~3 billion person profiles globally; ~250M+ US-business contacts |
| Hunter.io | Email finder + email verifier | ~107M companies indexed; ~210M+ verified business emails |
| Smarty (SmartyStreets) | US/intl address validation (USPS-certified) | Every deliverable address in 240+ countries |
| Twilio Lookup | Phone validation + carrier + line-type | Every routable phone number globally |
When you enrich a contact through LeadGen Engine, your request is routed to the right provider for the capability you asked for:
Combined, that’s an addressable universe of well over 180M+ business contacts — the limiting factor for any given customer is their LeadGen Engine plan budget, not the underlying provider coverage.
ZoomInfo and Apollo maintain their own pre-licensed databases of similar scale (~hundreds of millions of contacts each) and recoup costs via $5K–$50K+ annual seat-based contracts. LeadGen Engine accesses the same underlying provider ecosystem on a pay-per-call basis, which means:
Every integrated provider maintains compliance with GDPR, CCPA, and relevant US state privacy laws. LeadGen Engine doesn’t retain enriched contact data beyond your CRM-sync window unless you explicitly request historical enrichment storage. Suppression lists (bounces, unsubscribes, TCPA opt-outs) are honored portfolio-wide across all Jon Lynch Financial Group sales tools.
