Anti-Fragile take
Contact enrichment is harder than company enrichment because people move. A verified email from six months ago may already be stale. Enrichment without validation is building on sand.
We enrich contacts with waterfall providers, then validate every email and phone before it enters a sequence or dialer.
Why it matters
Bad contact data wastes rep time and burns domain reputation. Validation is not optional.
How we build it
Provider waterfall per field, Zerobounce/Hunter validation, and stale-contact flags on job-change detection.
