Apollo or ZoomInfo to find and contact prospects: data, CRM, pricing

One job, two ways of buying it

Both tools serve the same job: build a list of target accounts, find the right people, enrich the records and push them to the CRM. Apollo presents itself as a workspace for prospecting, outreach and dialing, with agents that research accounts and build lists. ZoomInfo presents itself as a go-to-market platform built on its B2B data, intent signals and AI agents.

The first practical difference is commercial. Apollo lists seat prices and a free plan. ZoomInfo describes a pricing logic but no amount, so a budget comparison starts with a quote request.

Contact data and filters: large claims, no shared yardstick

Apollo's current homepage claims 240M+ contacts and 30M+ accounts, while the usedby record still says 270M+. Apollo's homepage gives no reason for the difference, so treat its figure as the current claim. ZoomInfo claims 500M+ contacts and 100M+ companies, verified in part by 300+ human researchers. These are vendor declarations with different definitions. They say nothing about how many of your target contacts are present and correct, least of all in France or Europe.

On filters, Apollo describes searching by role, title and company traits. Its pricing grid separates basic filters on the Free plan from advanced filters and signals on paid plans, with intent topics rising from 1 to 6 to 12 across tiers. ZoomInfo cites firmographic, technographic and intent targeting, account scoring and org charts. In its pricing, intent signals, website visitors and buying-group filters appear from Copilot Advanced, not the entry Professional tier.

Enrichment and CRM: count what is native

Apollo lists waterfall enrichment, plus CSV, CRM and API enrichment, on its paid plans. Its CRM integrations cover Salesforce, HubSpot and Pipedrive, with Outreach and SalesLoft listed separately, and the homepage claims 200+ integrations overall. Enrichment is paid in credits: an email costs 1, a phone number 8, enriched data 1 to 8.

ZoomInfo says it cleans contact and company records across the tech stack, not only in the CRM. It lists native Salesforce, HubSpot and Microsoft Dynamics 365, plus 120+ other tools. Exporting emails to Outreach or Salesloft is listed from Copilot Advanced. The two figures count integrations differently, so check your own CRM by name and ask which fields are written back.

Pricing: seats and pooled credits versus licenses and exports

Apollo's grid shows Free at $0 with 900 credits per seat per year, Basic at $49 with 30,000, Professional at $79 with 48,000 and Organization at $119 with 72,000 and a three-seat minimum. Prices are per seat per month, billed annually. Credits are pooled, reset each cycle and do not roll over, and all seats must sit on the same plan. At 8 credits per phone number, a phone-heavy team drains its pool faster than an email-only one. The FAQ also mentions a Custom plan that the grid does not show, so confirm the exact tiers at checkout.

ZoomInfo says price depends on features, number of licenses and credit use; one credit is consumed per exported profile, and integrations can require a minimum bulk credit purchase. Its homepage FAQ, however, says it does not charge by fixed seat tiers, while the pricing page speaks of licenses. The two pages do not reconcile, so ask any quote to state which unit applies. No amount is published.

What customers show, and what they do not

Syncro, an IT management software company, had an inbound-only motion and no data vendor. In a ZoomInfo case study it describes using GTM Studio to find managed service providers by having the tool inspect company websites, to re-engage closed-lost deals using Chorus transcripts, and to route identified website visitors into sequences. Syncro reports 35 campaigns in a couple of months and about $400,000 of pipeline.

Snappy, a corporate gifting platform, reports that the rate at which early conversations become sales-qualified opportunities rose from about 30% to about 60%, and describes a rep who spotted a target account researching relevant topics through Copilot intent signals and booked a meeting that week. Vensure, built through nearly 100 acquisitions, uses ZoomInfo's core data to consolidate and enrich records across fragmented CRMs.

Apollo's own pages present its customers mainly as testimonials. Claiton's SVP of Sales reports email deliverability up from 72% to 94% and 47% more meetings; an account executive at Lyon Bakery describes searching large food companies by role and title. These come from different companies and metrics, so they are not a head-to-head benchmark.

Settling what the pages cannot

Editorial recommendation, not a vendor feature: run both trials on the same sample of your own target accounts, including French or European ones, and compare how many contacts come back, how many emails bounce, and whether records duplicate in your CRM. Apollo's trial includes 75 credits; ZoomInfo offers a free trial, and its homepage FAQ describes a permanent free Lite plan. Then ask ZoomInfo for a quote at your expected export volume and model Apollo's credits against your email-versus-phone mix.
