I'm a self funded geographic searcher that is doing broker and direct outreach. What databases have people found helpful for sourcing geographic lists? So far I've spent most time with Reference USA and Mergent Intellect. Both have plenty of noise, although it seems like Mergent Intellect has like 3X+ the noise. Basically it returns a huge amount of companies for a similar search, with more bad ones. Curious other people's thoughts on which databases they felt were best, or better yet, least bad.

Thanks!
