AI sales intelligence with B2B contact data and prospecting
Apollo.io combines a 275M-contact B2B database with AI lead scoring, sequencing, and meeting scheduling tools that replace Outreach plus ZoomInfo for many teams.
ShareTool Verdict- 8/10
The best value in B2B sales intelligence - the database depth rivals ZoomInfo at a fraction of the cost, and sequencing tools mean you can run outreach from one place
Sales teams praise Apollo for replacing multiple expensive tools with one affordable platform. Data accuracy gets mixed marks - emails are reliable but mobile numbers less so. Users upgrading from ZoomInfo plus Outreach consistently report significant cost savings.
“We replaced ZoomInfo and Outreach with Apollo and cut our sales stack cost by 60%. The data is slightly less accurate but the ROI math is not close.”
G2“The Chrome extension is a cheat code for LinkedIn prospecting. I can build a 50-person sequence in 20 minutes that used to take me 2 hours.”

ZoomInfo has more verified direct dials and better enterprise data accuracy. Apollo is 3-5x cheaper and includes sequencing tools that ZoomInfo charges separately for. Most teams under 50 reps choose Apollo; larger enterprise sales orgs often prefer ZoomInfo despite the cost.
Yes - no credit card required. The free plan gives you unlimited email credits (with daily limits) and 5 mobile number credits per month. It is enough to test the platform and do light prospecting.
Apollo has native two-way sync with Salesforce and HubSpot. Contacts, accounts, activities, and opportunities sync in both directions. Other CRMs can connect via Zapier.
Email accuracy is strong - Apollo estimates 91%+ deliverability on verified emails. Mobile direct dial accuracy is lower, typically 70-80%. Always verify before high-volume calling campaigns.

“Mobile number accuracy is hit or miss - I would say about 25% of the direct dials are stale or wrong. Fine for email, less reliable for calling.”

For most SMB and mid-market sales teams, yes. Apollo sequences cover A/B testing, auto-steps, LinkedIn tasks, and call integration. Enterprise teams with complex multi-channel workflows may still prefer dedicated sequencing tools.
