US C-Level B2B Leads

I need a fresh, accuracy-checked list of United States B2B contacts who sit at the very top of their organisations. Every record must belong to either a CEO, Managing Director or Chief Financial Officer. My immediate focus is on companies operating in business services, construction and finance, but if you uncover strong matches in technology or healthcare I am open to including them as well.

For each lead, I must have:
• company name
• verified corporate email address (no info@ or hello@)
• direct phone number or validated mobile line

LinkedIn profile URLs and any supplemental data you normally capture are a welcome bonus as long as the core fields above remain complete and clean.

Please deliver the data in a spreadsheet (Excel or Google Sheets) and indicate your source for each contact so I can spot-check accuracy. Duplicates, generic titles or non-US companies will be rejected.
