A neutral head-to-head comparison of Apollo.io and ZoomInfo across data coverage, prospecting, intent data, integrations, and pricing for B2B sales and RevOps teams.

## The short answer

Apollo.io and ZoomInfo are two of the most widely used B2B sales intelligence platforms, and both give sales teams a large contact database, filtering, and outreach tooling. The honest split comes down to scope and price: Apollo.io is an all-in-one, self-serve prospecting and engagement platform (data, sequences, dialer, and a lightweight CRM) priced per seat with a free tier, and it skews toward SMB, startup, and mid-market outbound teams. ZoomInfo is an enterprise GTM data platform with a larger verified database, intent data, website de-anonymization, and its Copilot AI, sold via annual contract with sales-led pricing and skewing toward mid-market and enterprise revenue orgs.

### Choose Apollo.io: Affordable all-in-one prospecting and outreach, self-serve

If you want data, multi-step sequences, a built-in dialer, and a lightweight CRM in **one self-serve tool**, sell into tech or SaaS with a **US-centric ICP**, and value transparent per-seat pricing with a **free tier to start**, Apollo.io is the more accessible pick (Basic $49/user/mo, Professional $79/user/mo, billed annually).

### Choose ZoomInfo: Broad, high-accuracy enterprise data with intent and Copilot

If you need broad, high-accuracy data across **many verticals and geographies**, require **intent data**, website de-anonymization, and mature CRM and RevOps integrations, and have budget for a **$30K to $60K/yr** annual commitment, ZoomInfo’s enterprise platform is the stronger fit (pricing is sales-led and negotiated).

## Vendor profile

### Apollo.io

*All-in-one prospecting + engagement platform · web app · per-seat pricing, free tier*

Apollo.io is a self-serve, all-in-one prospecting and engagement platform that combines a contact database with multi-step email sequences, a built-in dialer, and a lightweight CRM in a single tool. Its database covers roughly 265M to 275M+ contact profiles (marketing cites both figures) and around 30M to 73M+ company profiles depending on the source. Coverage is strongest for tech, SaaS, and startup ICPs and US-based B2B companies active on LinkedIn, and thinner in manufacturing, healthcare, government, and non-US SMBs. Apollo added an AI assistant in March 2026 that executes outbound via natural language. It has no standalone intent-data product, which is its main gap.

- **Vendor:** Apollo.io (apollo.io)
- **Platform:** Web app (SaaS)
- **Category:** All-in-one prospecting + engagement
- **Pricing model:** Per-seat tiered; free tier; annual or monthly
- **Starting price:** $0 (Free); Basic $49/user/mo (annual)
- **Public rating:** 4.7 to 4.8/5 G2 (~7,100 to 9,600 reviews); 4.5/5 Capterra (396)

### ZoomInfo

*Enterprise GTM data platform · web app · sales-led annual contract*

ZoomInfo is an enterprise go-to-market data platform built around a large verified B2B database, intent data, website de-anonymization, and its Copilot AI sales agent. Its database covers 500M+ contact profiles (Copilot materials cite 300M+ actively) and 100M+ company profiles, with 135M+ verified phone numbers and daily processing of billions of data points. ZoomInfo covers more industries and geographies more evenly than Apollo, which makes it the safer pick when the ICP spans multiple verticals or non-tech segments. It is designed to feed an external CRM and GTM stack rather than replace it, and it is sold through a sales-led annual contract with no public price list. Its G2 listing is now branded “GTM Workspace (Powered by ZoomInfo)”; confirm the listing name and count live before relying on it.

- **Vendor:** ZoomInfo (zoominfo.com)
- **Platform:** Web app (SaaS)
- **Category:** Enterprise GTM data platform
- **Pricing model:** Sales-led, annual contract; no monthly billing
- **Starting price:** No public price; quotes require a sales conversation
- **Public rating:** 4.5/5 G2 (~9,106, GTM Workspace listing); 4.1/5 Capterra (320)

## Pricing: what you'll actually pay

Pricing is the single largest difference between these two tools. Apollo.io publishes transparent per-seat prices and offers a free tier; ZoomInfo has no public price list and sells via a negotiated annual contract. Apollo figures are from Apollo’s published tiers; ZoomInfo figures are reported from secondary sources (Vendr marketplace, Cleanlist) as of July 2026 and vary by deal.

| **Per-seat add-ons**       | Included in per-seat price                                      | ~$1,500 to $3,000+/user/yr on top of platform fee            |
| **Billing model**          | Annual or monthly (monthly ~15 to 25% higher)                   | Annual only; no monthly billing                              |

## Capability comparison

Both platforms cover the sales-intelligence core: a large contact database, deep filtering, and outreach tooling. The gaps appear on intent data, engagement depth, website de-anonymization, and whether a CRM is built in. Apollo.io leads on all-in-one engagement and self-serve price; ZoomInfo leads on database scale, intent, and enterprise integrations.

## Strengths & tradeoffs

Both platforms do the core job well (surface B2B contacts and help you reach them), and each side wins rows the other does not. The honest differences are scope, data breadth, and price.

## Ratings & track record

| G2 rating       | 4.7 to 4.8 / 5                                           | 4.5 / 5 (GTM Workspace listing)                                   |
| G2 reviews      | ~7,100 to 9,600 (source-dependent)                       | ~9,106                                                            |
| Capterra rating | 4.5 / 5 (396 reviews)                                    | 4.1 / 5 (320 reviews, ZoomInfo Sales)                             |
| Category        | All-in-one prospecting + engagement                      | Enterprise GTM data platform                                      |
| Notable signal  | Higher public ratings; free tier and transparent pricing | Larger verified database; intent data and enterprise integrations |

On public ratings, Apollo.io sits higher on both G2 (4.7 to 4.8) and Capterra (4.5) than ZoomInfo (4.5 G2, 4.1 Capterra), though the two draw from review pools of broadly similar depth. Apollo’s exact G2 rating and review count vary by source and date because G2’s page blocked direct fetch, so the count is cited anywhere from roughly 7,142 to 9,645; confirm the current figure on g2.com before relying on it. Accuracy and deliverability comparisons come partly from vendor and vendor-adjacent pages, so treat them as directional rather than absolute, and weigh them against the independent Cleanlist test where possible. The choice here is about ICP breadth, workflow, and budget, not which tool is “better.”

*Both tools’ data is sourced from publicly available information and third-party cross-checks as of July 2026. Apollo’s G2 page and ZoomInfo’s negotiated pricing could not be fully confirmed via automated fetch; treat G2 counts and all ZoomInfo pricing figures as reported, and verify directly with each vendor before buying. This comparison is independent; we take no affiliate or referral fees from either vendor.*

## Frequently asked questions

### What is the difference between Apollo.io and ZoomInfo?

Apollo.io is an all-in-one, self-serve prospecting and engagement platform that bundles a contact database, email sequences, a built-in dialer, and a lightweight CRM, priced per seat with a free tier. ZoomInfo is an enterprise GTM data platform with a larger verified database, intent data, website de-anonymization, and its Copilot AI, sold via a negotiated annual contract with no public pricing. Apollo does more of the outreach workflow in one tool at a lower price; ZoomInfo offers broader, higher-accuracy data and enterprise integrations at enterprise cost.

### Is Apollo.io better than ZoomInfo?

Neither is better in the abstract. Apollo.io is better for SMB, startup, and mid-market outbound teams that want an affordable, self-serve tool with built-in sequencing and dialing, especially when selling into tech or SaaS with a US-centric ICP. ZoomInfo is better for mid-market to enterprise revenue orgs that need broad, high-accuracy data across many verticals and geographies, intent data, and mature RevOps integrations. The right pick depends on ICP breadth, workflow needs, and budget, not quality.

### Which is cheaper, Apollo.io or ZoomInfo?

Apollo.io is far cheaper. It starts free, its Basic tier is $49/user/mo annually, and a 5-person team typically spends roughly $3,000 to $7,200/yr. ZoomInfo has no public prices and sells via annual contracts; reported tiers start around $14,995/yr, per-seat add-ons run roughly $1,500 to $3,000+/user/yr, and most buyers land at $30K to $60K/yr all-in (Vendr median ~$33,500/yr). This is the single largest difference between the two.

### Does Apollo.io include intent data?

No. Apollo.io has no standalone intent-data product, and no add-on fills this gap. It offers job-change, hiring, funding, and technographic signals, but teams that run intent-driven ABM will need to look elsewhere. ZoomInfo includes company- and person-level intent data as a core strength.

### Does ZoomInfo publish public pricing?

No. ZoomInfo has no official public pricing page, and quotes require a sales conversation. Reported tiers (from secondary sources such as Vendr and Cleanlist) start around $14,995/yr for Professional, with Advanced and Elite higher, and per-seat add-ons stacked on top. All plans are annual with no monthly billing. Confirm current terms directly with ZoomInfo before committing.

### Which has more accurate data, Apollo.io or ZoomInfo?

Reported accuracy figures should be treated as directional, since many come from vendor and vendor-adjacent comparisons. In an independent Cleanlist test of 1,000 leads (March 2026), Apollo user reports cluster around 65 to 80% accuracy with email match around 78% and deliverability around 88%, while ZoomInfo claims 95%+ with around 92% deliverability in a comparative test. ZoomInfo generally covers more industries and geographies more evenly, which makes it the safer pick for multi-vertical or non-tech ICPs; Apollo is strongest for US tech and SaaS.
