USA B2B Lead List Needed

I need a fresh, accurate database of United States–based companies, complete with contact details for real decision-makers. I prefer a list from Apollo io, Zoominfo or any premium lead source. Leads quantity 10-50 million.

Mention the source of your lead list and the quantity you have.

Here’s what I expect:
• CEO, founder, Owner, C-Leven Contact
• Verified work email (95 %+ deliverability), direct phone, company name, website, industry, employee count, city/state, and LinkedIn URL
• No duplicates
• Final delivery in an Excel or CSV file, clearly structured and easy to filter

I’m comfortable with whatever research stack you prefer—LinkedIn Sales Navigator, Apollo, ZoomInfo, Crunchbase, Hunter, or your own proven workflow—as long as the data meets the quality bar above.

Please share a small sample of 20 leads so I can quickly confirm accuracy before we move to full production.
