Comparison
SIE Data vs ZoomInfo
ZoomInfo has a 420M+ contact database scraped from the web. SIE Data has 11M+ contacts verified by federal and state government registries. Different tools for different needs — here is an honest breakdown.
A note on honesty
ZoomInfo has a massive 420M+ contact database with global coverage and built-in email sequences. If you need broad international B2B data with integrated outreach, ZoomInfo may be the better fit. SIE Data is purpose-built for US businesses who need government-verified contacts, compliance-grade provenance, and permit-based intent signals — at a fraction of the cost.

SMBs who can't afford $15K/yr for ZoomInfo
Home services companies who need permit-based leads
Compliance-conscious buyers who need data provenance
Companies looking for government-verified contact data
Regulated industries that need an auditable data trail
Key differences at a glance
Government-verified data
Our contacts come from NPI (healthcare), FINRA/SEC (financial), FMCSA (moving/trucking), and state licensing boards — not social or web scraping. Every record has a verifiable source.
No $15K commitment
Start with 25 free credits/mo, no credit card. Scale to month-to-month plans when ready. ZoomInfo requires annual contracts starting at $15,000/yr.
Compliance built in
FCRA firewall blocks regulated data by default. DROP-compliant deletion on request. Full provenance chain for every signal. Not an add-on — it is the architecture.
Enterprise trust — where SIE wins on procurement
Procurement teams at large prospects flag ZoomInfo's TOS disputes + lack of record-level consent provenance as a blocker. SIE ships these as first-class trust artifacts.
Demo scheduling cycle runs 2-4 weeks before any data touches a sandbox.
Email in, 10K sample signals + scoped JWT in 60 seconds.
Deletion exposure from CCPA/GDPR requests is not publicly quantified.
Shows % of supply that is deletion-resistant, updated hourly.
No external-facing verify API; provenance questions route through support.
External auditors can independently verify record-level provenance.
Reports shareable under NDA; control-level workflow remains opaque.
Append-only evidence log makes Type II audit faster when engaged.
Each prospect runs CAIQ/SIG back-and-forth through the account team.

Effective cost-per-contact is not visible without a quote.
Sliders show ARR, overage, and effective $-per-reveal live.
The moat isn't marketing — every claim above links to a live endpoint or shipped artifact. Your security team can verify the moat before your procurement team even starts reviewing vendors.
