Five layers of verification ensure every contact meets the highest data quality standards.
We aggregate data from over 100 independent sources including public filings, corporate websites, professional networks, press releases, job boards, and proprietary data partnerships. Each data point is cross-referenced across multiple sources to establish a confidence score before it ever enters our database.
Machine learning models trained on billions of data points detect anomalies, inconsistencies, and outdated information automatically. Our AI identifies patterns like job title changes that typically follow funding rounds, company restructurings, or seasonal hiring cycles, flagging contacts for re-verification proactively.
Every email address is validated against SMTP servers to confirm the mailbox exists and accepts messages. Phone numbers undergo carrier lookup and line status verification. This direct channel verification layer catches invalid contacts that source-level checks alone would miss.
Edge cases and low-confidence records are escalated to our data quality team for manual review. This human-in-the-loop approach catches nuanced issues that automated systems miss, such as contacts at recently acquired companies or executives who hold roles at multiple organizations simultaneously.
Validation does not stop after the initial check. Every contact in our database is re-verified on a rolling 90-day cycle. We monitor for job changes, company closures, email bounces, and phone disconnections in near real-time, automatically updating records and flagging stale data before it reaches your team.
