Apollo reviews

  • Rated 3.0 out of 5User12,700 verified calls
    Billed per call, not per hit, so misses cost money. Accuracy trails the dedicated finders. Fine if you already live in Apollo for search.
    Jordan K., RevOps consultantApollopeople.email.find
  • Rated 4.0 out of 5User11,000 verified calls
    Broad coverage. Accuracy is the weak spot on titles; about one in seven needed a correction when we spot-checked 200 records.
