Apollo vs ZoomInfo vs Cognism: B2B Data 2026

If you are choosing a B2B data provider in 2026, the short version is this: Apollo is the only one of the three that publishes its pricing, ZoomInfo and Cognism are both quote-only, and none of them will give you a database that is actually accurate. Contact data decays whether you pay $49 a seat or $40,000 a year, so the real question is not "which provider is best" but "which provider covers my ideal customer profile and region for the least money."

This compares Apollo, ZoomInfo and Cognism on coverage, pricing model, and compliance, and then makes the contrarian case that a lot of teams reading this should buy the cheapest option that covers their region — or spend the money cleaning the data they already own instead.

First, a disambiguation that trips up more people than it should: ZoomInfo is a B2B data company and has nothing to do with Zoom Video Communications. Different companies, different products, no shared ownership. ZoomInfo changed its Nasdaq ticker from ZI to GTM in May 2025 and repositioned itself as a broader "go-to-market" platform, per its May 2025 release announcing the ticker change and its GTM Studio product. The company and its flagship data product are still called ZoomInfo.

Pricing and package details below reflect each vendor's own public pages as of 18 July 2026. Where a vendor does not publish a number, we say so rather than laundering a figure from a comparison blog or a procurement marketplace — those third-party numbers are routinely stale or invented, and you have no way to audit them.

Pricing: only one of the three tells you the price

This is the cleanest differentiator in the whole comparison, so start here.

Apollo publishes real, self-serve pricing

Apollo's pricing page lists four tiers, billed annually, as of 18 July 2026: a Free plan at $0, Basic at $49 per user per month, Professional at $79 per user per month, and Organization at $119 per user per month with a 3-user minimum. Each paid tier bundles a yearly credit allotment for email, mobile and export lookups that scales with the tier, and Apollo revises those allotments periodically — confirm the current credit counts on the page before you budget. Larger deployments can also negotiate a custom plan, but the four listed tiers are all publicly priced, which is the point.

Two things make Apollo structurally different from the other two. You can sign up with a credit card and start today, and there is a genuinely usable free tier. That lowers the stakes of being wrong to almost nothing, which matters a lot given how uncertain the "which provider" question really is.

ZoomInfo is quote-only

ZoomInfo does not publish pricing. Its site routes you to a sales conversation, deals are annual contracts, and seat minimums apply. The confident dollar figures quoted all over the internet come from third-party aggregators or customer anecdotes, not from ZoomInfo, so we are not repeating them as fact. What is reliably true: expect an annual commitment, a multi-seat minimum, and a first quote that functions as an opening negotiating position rather than a fixed price.

Cognism is quote-only, sold in bundles

Cognism also does not publish prices. Its pricing page lists packages — Standard and Pro (each described as including 5 seats), plus CRM Enrichment and a Data-as-a-Service option priced on data volume — but every one routes to "talk to sales." The "5 seats included" framing tells you Cognism sells in bundles rather than one seat at a time, which makes it a poor fit if you genuinely need only one or two licenses.

The honest read on pricing: if transparent, low-commitment pricing matters to you — and for most small and mid-sized teams it should — Apollo wins this category by default, because you can see the number and walk away for free. The de-stacking corollary is in our sales tech stack audit guide: a quote-only vendor is not automatically better because it is expensive and gated, and "we pay $40k so it must be premium" is not a data-quality argument.

Data coverage and regional fit

Every vendor claims the biggest, most accurate database. Ignore the raw record counts — a provider can hold 200 million contacts and still miss the fifty accounts you actually sell to. What matters is coverage of your ideal customer profile in your region.

ZoomInfo is generally strongest for US and North American company and contact data, especially mid-market and enterprise firmographics, org charts and intent signals. If you sell into large North American companies and need depth — reporting hierarchies, technographics, buying-intent data — this is the category ZoomInfo has historically owned, and it is the main reason teams tolerate the price and the annual lock-in.

Cognism built its reputation on EMEA coverage and phone data. If you prospect into the UK and Europe, Cognism's compliance posture and its human-verified mobile numbers are the specific reasons to look at it over the US-centric incumbents. That regional strength is real and is the clearest single reason to pick Cognism.

Apollo offers broad coverage with a US lean, and pairs the database with a full prospecting and sequencing workspace, so a lot of teams use it as data and outreach in one tool. It overlaps with the lighter end of the engagement-platform market; if that is what you are really shopping for, our roundup of sales engagement platforms including Apollo covers where the all-in-one approach helps and where a dedicated tool wins.

The practical test beats any vendor claim: during a trial, pull 100 contacts matching your exact ICP and manually check email deliverability and phone accuracy on a sample. The provider that wins that test for your list is your provider, regardless of who has the larger headline database.

Compliance: GDPR, CCPA, and Cognism's phone verification

Compliance is where the providers diverge in posture, and it matters most if you prospect into Europe.

All three state GDPR and CCPA compliance. Cognism leans on compliance hardest as a positioning, describing a "compliance-first" database that notifies business contacts, tracks consent, and scrubs against Do-Not-Call and TPS lists across multiple territories. If your legal team is nervous about outbound into the EU and UK, that documented posture is a legitimate reason to prefer Cognism — not because the others are lawless, but because Cognism has built its pitch around being the safe choice there.

Cognism's signature feature is Diamond Data. Cognism defines it as mobile numbers its team phone-verifies by actually calling them to confirm the right person answers, rather than numbers merely aggregated from other sources. Cognism markets a materially higher connect rate for these verified numbers — on the order of a 3x improvement — but read that claim precisely: it is Cognism's own figure, and it applies to the Diamond-verified subset, not to the entire database. No provider's full database dials at that rate. Human-verified phone data is a real, defensible advantage if your motion is cold-calling into EMEA; just don't extrapolate the headline number to every record you'll pull.

The broader compliance truth applies to all three: a provider handing you a compliant record does not make your outreach compliant. Consent basis, suppression handling, and honoring opt-outs are your obligations once the data is in your CRM, whichever vendor sold it to you.

The de-stacking take: you probably don't need the premium tier

Here is the part the vendors won't tell you, and the reason this site exists.

Contact data decays fast, and no provider is fully accurate. People change jobs, direct dials get reassigned, and email addresses die constantly, so a meaningful share of any B2B database is stale within a year. You are not buying a permanently correct dataset from anyone — you are renting a snapshot that starts decaying the moment you export it. That single fact reframes the purchase: paying a large premium for "the most accurate data" buys you a snapshot that is marginally less wrong, not one that is right.

So the honest default for most teams is buy the cheapest option that covers your ICP and your region. If you sell into US mid-market, test whether Apollo's coverage is good enough before you sign a five-figure ZoomInfo contract — often it is. If you sell into EMEA and live on the phone, Cognism's regional and phone-verification strengths may justify it over a cheaper US-centric database. Let the region and the motion decide, not the sticker price or the sales rep's confidence.

You almost certainly don't need all three. These platforms overlap heavily. Running two general-purpose data providers side by side is one of the most common forms of B2B-data overspend, and it usually happens by accident — a new VP brings their preferred tool, nobody cancels the old one, and you now pay twice to enrich the same contacts. Pick one primary provider. Add a second only for a specific, named gap the first genuinely can't fill, like EMEA phone coverage that your US-centric primary lacks.

You may not need the enterprise tier, either. The upgrade from a mid tier to an enterprise contract typically buys intent data, deeper integrations, and higher credit ceilings. Those are worth real money to a team that will operationalize them — a RevOps function that acts on intent signals weekly. They are worth nothing to a team that exports a list once a month and calls it. Before you buy intent data, be able to name the person who will act on it and the workflow they'll run. If you can't, you're buying a dashboard nobody opens.

And sometimes the answer is better hygiene on data you already own. If your connect rates are poor, the cause is often a neglected CRM full of stale records, not an inferior data vendor. A one-time enrichment and de-duplication pass against contacts you already have — Cognism even sells this as a standalone CRM Enrichment package — can beat buying a whole new prospecting seat for every rep. Fix the data you're already paying to store before you pay a second vendor for more of it. The same discipline that keeps a small-business CRM from bloating applies to your data spend.

Who should buy which

Buy Apollo if you want transparent pricing, a low-commitment start, or an all-in-one data-plus-prospecting workspace — and especially if you're a startup or SMB where a five-figure annual data contract is not remotely justified yet. The free tier means you can validate coverage against your ICP before spending anything.

Buy ZoomInfo if you sell into US and North American mid-market or enterprise accounts, you need deep firmographics, org charts and intent data, and you have a RevOps team that will actually use them. Go in knowing it's an annual, quote-only commitment and that the first quote is negotiable.

Buy Cognism if you prospect into the UK and Europe, cold-calling is central to your motion, and phone-verified mobile numbers plus a compliance-first posture are worth paying for. Its bundled seat packages make it a weak fit for one- or two-person teams.

Buy none of them — or just the cheapest — if you're a small team that closes from inbound and referrals, or your CRM already holds more contacts than you're working. In that case the money is better spent cleaning what you have. If you're mid-way through a broader stack review, our outreach vs Salesloft comparison makes the same point about the engagement layer: teams routinely buy more platform than their motion requires.

Frequently Asked Questions

Is ZoomInfo the same company as Zoom?

No. ZoomInfo is a B2B contact and company data provider; Zoom Video Communications is a video-conferencing company. They are entirely separate businesses with no shared ownership or products. ZoomInfo changed its Nasdaq ticker to GTM in May 2025 and now positions itself as a go-to-market platform, but its data product is still called ZoomInfo.

Does Apollo publish its pricing?

Yes. As of 18 July 2026, Apollo's pricing page lists (billed annually) a free plan, a Basic plan at $49 per user per month, a Professional plan at $79 per user per month, and an Organization plan at $119 per user per month with a 3-user minimum, with yearly credit allotments that vary by tier. This transparency is a genuine differentiator, because both ZoomInfo and Cognism are quote-only. Always confirm the current figure and credit limits on Apollo's own page before budgeting.

How much does ZoomInfo cost?

ZoomInfo does not publish pricing. It sells annual contracts through a sales quote with seat minimums, and the specific dollar figures you'll find in comparison articles come from third-party aggregators or customer anecdotes, not from ZoomInfo. Expect an annual commitment and treat the first quote as a starting position to negotiate from.

What is Cognism's Diamond Data?

Diamond Data is Cognism's set of mobile phone numbers that its team verifies by actually calling them to confirm the right person answers, rather than aggregating numbers from other sources unchecked. Cognism markets a significantly higher connect rate for these verified numbers, though that claim is Cognism's own and applies to the Diamond-verified subset, not the whole database. It's a real advantage for teams whose motion depends on cold-calling, particularly into EMEA.

Which B2B data provider is best for Europe?

Cognism is the strongest of these three for UK and European coverage, both for its phone-verified mobile data and for its compliance-first GDPR positioning. ZoomInfo and Apollo lean US-heavy, so a team prospecting primarily into EMEA should weight regional coverage over headline database size. Always test a sample of your actual ICP contacts during a trial rather than trusting any coverage claim.

Do I need more than one B2B data provider?

Almost never. Running two general-purpose data providers is one of the most common forms of B2B-data overspend, usually because a duplicate tool was added and the old one never cancelled. Pick one primary provider that covers your ICP and region, and add a second only for a specific gap the first genuinely cannot fill, such as EMEA phone data your US-centric provider lacks.

Is it worth paying for the enterprise tier and intent data?

Only if someone will operationalize it. Intent data and enterprise integrations are valuable to a RevOps team that acts on signals regularly, and worthless to a team that exports a list once a month. Before upgrading, name the person who will use the intent data and the workflow they'll run; if you can't, stay on the cheaper tier and put the savings toward cleaning the data you already own.
