Bought a sample first. Connect rate jumped noticeably once we filtered by category. Bought it while building a homeopathic doctor doctor prospecting workflow for India. One column I'd add next refresh: secondary email.
Live-tested 30 random rows before committing. Categorisation was granular enough to segment by sub-vertical without regex. No complaints from the field reps.
Pulled the trigger after reading the row count. Cross-checked 50 entries against Google Maps and 47 matched cleanly. Will reconsider for the next refresh.
