Editorial Verdict

AI-researched, not hands-on tested

Apollo.io's database scale is real -- 240M+ contacts and 30M+ companies, consolidating data, outreach, and CRM into one tool to cut tech-stack costs. The honest catch: data accuracy is the most-cited complaint (500+ G2 reviews flag outdated titles and dead emails), bounce rates run 15-35% even on 'verified' contacts, and international data quality is notably weaker outside North America.
