CEO Contact Research Needed

I have a spreadsheet of company domains that cut across multiple industries and I need to match each one with its top-most executive—ideally the CEO or, when that role is absent, the President.

For every domain, please give me:
• The executive’s first and last name only (no middle initials or extra titles).

The list will be considered complete when every domain on my sheet is paired with a clearly documented CEO or President whose name can be verified by the link you supply. A simple CSV or Google Sheet is fine for delivery; use separate columns for Domain, First Name, Last Name and Source URL.

Also, I want it send in this format Domain/FirstName Last Name
