B2B lead lists that don't suck.

LeadListHQ is a B2B lead generation company I'm helping start. Most lead lists are full of dead emails, role accounts, and duplicates pretending to be different people. We're trying to build the version that isn't. The pipeline checks every contact, throws out anything stale, and only ships rows that pass.

01

Verify, don't just enrich.

Most lead-gen tools enrich whatever you give them. We verify first. Email is checked against MX records and a deliverability probe. Job title is cross-referenced against current LinkedIn. Anything stale is dropped, not flagged.

02

Targeted by behavior, not just firmographics.

"Companies in fintech, 50 to 500 employees, in the US" is a starting point. Better is "companies whose engineering team posted on the API in the last 90 days" or "companies that hired their first VP of Sales this quarter." We support both.

03

You only pay for verified rows.

Pricing is per verified contact, not per credit, not per query, not per seat. If we can't verify it we don't bill for it. If you find a row that bounces in the first 30 days we replace it.
