Apollo.io

All-in-one sales intelligence + engagement at $79-$149/seat.

By Apollo.io, Inc. · Founded 2015 · San Francisco, CA · private

Apollo.io is the strongest all-in-one sales intelligence + engagement platform. Combines a 275M+ B2B contact database with cadence + dialer + email tracking + AI features at $79-$149/seat/mo, meaningfully cheaper than Outreach/Salesloft for comparable depth. Best fit for SMB-mid-market outbound teams (10-200 reps) wanting consolidated tooling. Trade-offs: contact data quality variable in non-US markets (Cognism better in EU), some advanced cadence features thinner than Outreach, and the Apollo AI add-on is the AI SDR product (covered separately as `apollo-ai`).
