Apollo
All-in-one B2B sales intelligence + engagement platform: a 275M+ contact database, email sequences, and a dialer in one tool.
Apollo.io packs a B2B contact database, email sequencing, and a built-in dialer into one platform for a fraction of what ZoomInfo charges, making it the strongest all-in-one prospecting tool for SMB and mid-market sales teams. Data accuracy that trails the enterprise incumbents and annual-first billing are the only real caveats, leaving it a clear Strong Buy.
