BnB & ZoomInfo Alternatives

Hello!

I am setting up an automated process for our deal flow and the first step is to cast a wide net of potential opportunities. I am looking to curate a customized list based on NAICS, Location and EBITDA range but am discovering that a lot of the business databases are quite expensive. I was wondering if you all had run into similar issues and were able to find a work around. I am currently looking into InfoUSA and 'USCompaniesList.com' but would welcome suggestions.

Thanks,
Chris
