Improving Accuracy of Clay's Find People Feature: Tips & Feedback

How accurate is clay’s “find people” feature when having it find people from imported companies? Just selected 25 companies and applied some simple (but broad) filters and it only returned 30 people. Based on companies and me looking at their LinkedIns, I should received a lot more. Wondering if there is anything special any y’all do to get this to work better, or if this is a better option to do this in clay? Any feedback/suggestions would be appreciated!
