Sales intelligence

Access accurate and rich buyer data

With the largest and most accurate B2B database of 275+ million contacts, Apollo helps you build lists and filter with precision using over 65 data attributes, so you can find your perfect leads.

Apollo is two platforms in one with the capabilities of Salesloft and Outreach, plus ZoomInfo. It saves us clicks, saves us time, and allows us to create automated sequences—something we struggled to achieve with our existing tech stack.

We were paying Outreach $18,000. ZoomInfo must have been another $15,000. When we did the migration Apollo was $12,000. We paid less for one tool than two tools together. We basically went from paying $35,000 for two tools to $12,000 for one. We cut our costs in half.
