Apollo.io
The all-in-one sales intelligence + engagement platform that made ZoomInfo-level data affordable to SMBs.
What Apollo.io is
Apollo.io is a San Francisco-based sales technology company founded in 2015. The product combines a 275M+ B2B contact database with sales-engagement (sequences, dialer), meeting scheduling, and workflow automation — the categories previously served by ZoomInfo + Outreach + Salesloft, at a fraction of the cost.
Who uses Apollo.io
SMB and mid-market sales teams that need enterprise-adjacent data quality without enterprise pricing. Especially strong for outbound SDR teams, founder-led sales, and B2B agencies running lead-gen for clients.
What Apollo.io costs
Free tier includes 60 email credits/month. Basic ~$59/user/month, Professional ~$99, Organization ~$149. Enterprise pricing custom. Most SMB sales teams run Basic or Professional. Meaningfully cheaper than ZoomInfo or Outreach individually — let alone both combined.
