What it is
Apollo combines a B2B contact database, a sales engagement platform (sequences, dialer, email tracking), and basic AI assistance into one tool. It’s the “good enough at everything” choice for sub-$10M ARR teams who don’t want to assemble Outreach + ZoomInfo + Salesloft as separate vendors.
Why it shows up in RevOps stacks
- Database + sequencer in one. Search Apollo’s database, push results into a sequence, dial out — no glue between tools.
- Permissive pricing. Free tier is genuinely useful; paid plans are a fraction of what equivalent capabilities cost from Outreach + ZoomInfo.
- Decent CRM sync. Bi-directional with HubSpot and Salesforce; not as deep as native sequencers but adequate for most teams.
Pricing
- Free — limited daily credits, 250 emails/day
- Basic — $49/seat/mo, 5,000 credits
- Professional — $79/seat/mo, dialer, AI assistance
- Organization — $119/seat/mo, advanced reporting, advanced security
Best for
- Early-stage and growth teams wanting integrated prospecting + outreach in one tool
- SDR teams of 5-25 reps who don’t need enterprise-grade engagement (Outreach/Salesloft tier)
- Teams that pair Apollo with Clay — using Apollo for the dialer and basic sync, Clay for higher-quality enrichment and orchestration
Watch-outs
- Data accuracy is a step below ZoomInfo and Apollo+Clay enrichment together usually outperforms Apollo alone
- AI features are basic compared to Claude / Gong / Clay-with-AI-columns
- Once you hit serious deliverability/compliance scale, you’ll likely add a dedicated infrastructure layer (Smartlead, Instantly) and demote Apollo to data + dialer only
