Case studies · Lead pipeline · Independent · Apr 2026–present
351 live companies. 456 contacts. Zero invented CRMs.
A lead pipeline I ran in production: every job posting re-checked at the ATS, every tech install proved from first-party signals, every LLM claim dropped if it was not on the page.
What changed
- 351 companies verified live at Greenhouse, Lever, Ashby, Workable, or Teamtailor — not a cached index of filled roles.
- 456 contacts resolved across 219 of those companies.
- 5,000+ accounts through a 13-prompt pipeline. Any claim not on the source page was dropped. Extractors abstained when confidence was low.
- HubSpot portal IDs and GA4 measurement IDs extracted as proof. A vendor named in copy is not an install.
- Unverified emails quarantined. A human accepted, rejected, or corrected before Instantly sent.
Why it mattered
Stale lists burn domains. Hallucinated CRMs burn the next email. I had already watched an extractor of mine read a truncated job description and almost report the wrong CRM into a live campaign. The outcome is not “more leads.” It is rows you can open at the source.
How
- Five ATS APIs. Source + timestamp on every row.
- Tech detection from DNS, headers, cookies, resource hosts — not page text.
- ~1,500 lines against a sending API: rate caps, timezone send, suppression.
- Clay CLI waterfall + verification. Next.js operator UI.
Same install for a sales team that is already buying lists they cannot defend.
