Where ZoomInfo and Apollo is the right call
Sales team that browses to find prospects
If your SDRs spend their day inside a tool clicking through filters and saved searches, ZoomInfo's UI is meaningfully better than ours. We're not optimizing for that workflow.
Need 50+ seats at the same company
At enterprise scale, the per-seat model with bulk discounts can be cheaper than per-record. Run the math.
Mature integrations with every CRM
ZoomInfo has spent 10+ years on Salesforce, HubSpot, Outreach, SalesLoft, Gong integrations. We have webhooks; that's enough for most teams but not all.
Where LeadGen Engine is the right call
Programmatic / agentic workflows
Per-call billing kills the unit economics of LLM-driven sales agents. Our flat subscription + stable API + predictable per-record cost makes the agent pattern work.
Variable usage volume
If you only need 1,000 lookups one month and 10,000 the next, our subscription tiers fit that reality. Per-seat models charge the same either way.
Teams under 10 SDRs
The per-seat math doesn't favor small teams. We do.
Real-time verification matters
Outbound campaigns die when bounce rates are high. Verification at enrichment time (not last quarter's batch) keeps sender reputation alive.
Procurement-averse buyers
Sign up with a credit card, drop the API key in your environment, ship. No procurement cycle. No annual contract.
Insurance-vertical needs
Pairs natively with ProducerLens for insurance license verification on enriched contacts. Cross-product flow that single-vertical competitors can't match.
How to decide
The honest answer: it depends on your usage shape. Above we've laid out the trade-offs by dimension. The fastest way to know which is right for you is to try us — sign up takes minutes, the free tier handles real evaluation, and you keep your existing tooling running in parallel.
Most successful customers don't fully replace their existing tool — they layer us in for the workflow we're better at and keep the incumbent for what it's better at. Hybrid is fine.
Frequently asked questions
- How does LeadGen Engine pricing actually compare to ZoomInfo?
- Depends on usage. ZoomInfo's typical mid-market contract is $15K–$25K/year for 3–5 seats with usage caps. LeadGen Engine Growth tier is $149/mo ($1,788/year) for 5,000 enrichments/month. If you're using <5,000 enrichments per month total team-wide, we're 8–14× cheaper. Above that, the math gets closer.
- Is your data quality comparable?
- Email verification rate is 95%+ at the time of enrichment. Direct-dial coverage and firmographic depth vary by company size — we return a confidence score with every field so you know what to trust. ZoomInfo's database is older and has more historical depth; ours is fresher per record.
- Can I use both?
- Yes. Some customers use ZoomInfo for the SDR-browsing workflow and LeadGen Engine for the programmatic enrichment pipeline. Different jobs.
- Do you have CRM integrations?
- Webhooks first, native connectors as we ship them. Webhooks cover Salesforce, HubSpot, Pipedrive, and any system with a webhook receiver — which is essentially all of them. Native connectors are on the roadmap by request priority.
- Is GDPR compliant?
- Yes. We process EU contact data under legitimate-interest basis with documented opt-out handling. EU residents can request deletion through a GDPR API endpoint.
- Can I get a custom enterprise tier?
- Yes — 25K+ enrichments/month custom Scale tier with SLA, dedicated webhook channel, and priority support. Email [email protected].
