Apollo vs ZoomInfo: which B2B data platform should you buy?
Apollo and ZoomInfo both promise verified contacts and intent, but they sit at opposite ends of the price and coverage spectrum. Here's how to choose.
By TheSharkStack · June 12, 2026
Apollo and ZoomInfo are the two names that come up first in any prospecting-data conversation, but they’re built for different buyers. One is a self-serve, all-in-one tool you can start free; the other is an enterprise data platform sold on annual contracts. Picking wrong means either overpaying or outgrowing your tool in six months.
The short answer
- Choose Apollo if you’re a startup or SMB that wants data and light sequencing in one affordable, self-serve tool.
- Choose ZoomInfo if you’re mid-market or enterprise, sell mostly into the US, and need the deepest coverage, org charts, and intent, with the budget to match.
Data coverage & accuracy
ZoomInfo still leads on raw US coverage, org-chart depth, and buying-committee mapping. Its data team and research operation are larger, and it shows on enterprise accounts.
Apollo’s 275M+ contact database is enormous and improving fast. Accuracy is strong on mainstream US roles but slips on smaller companies and non-US markets. For most SMB motions, it’s more than good enough, and the free tier lets you test it on your exact ICP before paying.
If your territory is Europe, note that neither is the strongest pick, Cognism typically wins on EU phone data and GDPR posture.
Features beyond data
This is where Apollo separates itself on value: it bundles sequencing, a dialer, and a Chrome extension into the same subscription. For a small team, Apollo can credibly replace a separate data vendor and a separate engagement tool.
ZoomInfo is a platform too (intent, workflows, enrichment, websites-visitor data), but its engagement features are an upsell, and you’ll usually pair it with Outreach or Salesloft anyway.
Pricing
- Apollo: free plan to start; paid from roughly $49/seat/mo. Credit limits are the main constraint.
- ZoomInfo: custom annual contracts, typically $15k+/yr, with seat- and feature-based add-ons. No meaningful self-serve.
The verdict
For founders, SMBs, and most scaling startups, Apollo delivers 80% of the value at a fraction of the cost and commitment. Move to ZoomInfo when US enterprise coverage, org charts, and intent become the bottleneck, and you have the budget and process to use them. Compare them side by side here.
