LeadQC verifies 1,000+ B2B leads per minute at 99.99% accuracy, cutting days of QC to minutes.
Grounded in available product and source data
Manually verifying a list of B2B leads can eat days and still miss bad data — LeadQC is B2B lead verification at scale instead, built to check 1,000+ leads per minute against live professional data sources rather than a person spot-checking profiles by hand.
The workflow itself compresses that entire process into three steps: upload a CSV of any volume from any lead source or CRM, run it through an AI validation engine applying 44 rules across 35+ data points, and download both a clean, verified file and an error report showing exactly why each rejected lead was flagged.
Two distinct verification layers do the actual checking. Live profile verification confirms email syntax and MX records, domain authenticity, current employment and job title accuracy, and decision-maker status, auto-removing freelancers, students, and unemployed contacts along the way; RFP-based verification separately cross-references inbound submission data against live records for vendor match, compliance, and specification alignment before anything reaches a sales team.
The site backs its own claims with concrete figures: 99.99% verification accuracy, 32M+ leads verified overall, and 2.4M+ unqualified contacts automatically removed from B2B pipelines in the last 30 days alone. A built-in savings calculator translates that into a stated 91% cost reduction for a sample monthly lead volume, alongside customer quotes attributed to named individuals at named companies citing similar results.
On security, the site states LeadQC is GDPR and SOC2 compliant, end-to-end encrypted, and backend-only — no external platform login or credentials are required to run a verification, and no user-level access to a company's other platforms is granted. A free 100-lead sample audit with a report inside 24 hours is available with no credit card required.
No — the site states verification runs through secure backend integrations with no external platform login, license, or credential required at any step.
They're excluded from the clean output file and listed separately in an error report with the specific reason each one was flagged, so a sales team can see what was removed and why rather than just a smaller unexplained list.
That's the specific job of RFP-based verification, separate from everyday prospect-list checking — it cross-references the submission itself against live records before a response ever gets treated as a real, qualified vendor.
Yes — a free 100-lead sample audit is available with a report delivered within 24 hours and no credit card required, meant to show accuracy on a real sample before a larger commitment.
Alongside it — LeadQC's job stops at producing a clean, verified file; a team still uploads that output into whatever CRM or outreach tool is already in use, since the site doesn't describe it as a CRM replacement itself.
The page reviewed doesn't specify a stated retention window for processed lead files after verification completes — worth confirming directly before uploading a batch containing regulated personal data, especially for GDPR-scoped teams.
