I realize this is an absolutely unhinged thing to ask for: Can anyone direct me to a large database of company names with websites (just those two columns), ideally 100K rows or more, that I can access for free? Basically this database if it had another column with the company name: https://github.com/cygenta/top10million (but doesn’t need to be anywhere near 10 million)
A lot of public libraries offer access to ReferenceUSA through your library card. I vaguely remember that queries are pretty customizable on there, and exportable to various formats. Despite the generic name, it’s specifically for businesses. Would that work?
