Cognism vs ZoomInfo (2026): EMEA Mobiles or US Depth, and What Each Seat Really Costs

Choose Cognism if most of your calls go to UK and European mobiles and you have five or more sellers. Choose ZoomInfo if most of your pipeline is North American, or if you want intent data, website visitor identification and outreach workflows in one contract.

Price does not separate them. In the quotes heard on Spona's sales calls, the median Cognism seat costs $3,831 a year and the median ZoomInfo seat $3,835. That is our calculation from six single-buyer lines per vendor, not a market price. Geography settles the Cognism vs ZoomInfo question, and team size breaks ties.

Three corrections to the pages that rank for this search shape the verdict. The compliance gap is do-not-call screening, not GDPR. Cognism's packages include 5 seats, so a team of four pays for an idle seat. And ZoomInfo's data is not US-only: it says 55% of its data sits outside North America.

Cognism vs ZoomInfo: the verdict by team

The two vendors agree on the split more than their marketing suggests. ZoomInfo's own page says Cognism suits sales teams that "prospect mainly in Europe and want phone-verified mobile numbers". It claims the wider platform for itself: European depth plus global scale, with signals and AI in one place.

Cognism's page makes a narrower case. It says European coverage comes as standard, while ZoomInfo sells region-specific "Data Passports" under a separate license. Neither page prints a price. The 12 quotes in the pricing section fill that gap.

Cognism vs ZoomInfo: coverage by region

Does Cognism have better European data? Both vendors place its strength in phone-verified mobiles for Europe. ZoomInfo claims the larger database, Europe included. Neither vendor publishes a same-sample test, and Spona has not run one, so this post makes no accuracy verdict.

ZoomInfo's counts are public. It claims 500M+ verified contacts and 100M+ company records. Its coverage page counts 158.5 million company locations across 122.9 million distinct companies. For Europe alone it claims 22.2M companies.

Cognism publishes no contact total. Its data page says director-level and above records are refreshed every 30 days. Its pitch is depth in the UK and EU, with mobiles a researcher has checked.

Review themes point the same way. AiSDR's summary of G2 reviews says ZoomInfo's coverage "drops sharply outside North America", with accuracy falling "particularly on direct mobile numbers". For Cognism, it says coverage "thins outside Western Europe".

Spona's own deal records show where each tool sits. ZoomInfo came up in 7 of Spona's 26 closed US deals, Cognism in two. Across 111 European deals the order flipped. Cognism came up in 15 and ZoomInfo in 11.

Those 11 European appearances matter. "US-centric" describes where your dials and your visitor identification needs sit, not where ZoomInfo's records stop.

Cognism vs ZoomInfo: phone data

Cognism checks mobiles by hand. ZoomInfo verifies at scale. That is the phone-data difference in two sentences, and it decides the UK side of the verdict.

Cognism runs a team of researchers who manually validate mobile numbers, a dataset it calls Diamond Data. On-demand verification, where you ask for one specific number to be checked, sits in the Pro package only. Cognism also claims a 3x improvement in connect rates over the industry average with those mobiles. It gives no method for that figure, so treat it as a vendor claim.

ZoomInfo counts 135M+ verified phone numbers. Its Professional package includes mobile numbers, business email and "intelligent dialing". Cognism sells no dialer. Its numbers go into your own dialer or CRM.

One buyer who kept Cognism and added Spona put the trade-off in a sentence. A UK sales director at a company of 51 to 200 staff told us: "Our calling team likes the numbers; we still need more target companies." That is the Cognism pattern in Spona's records. The phone data holds, and the account list runs out.

Cognism vs ZoomInfo: compliance

The compliance difference is phone screening, not GDPR. Both vendors hold ISO 27001 and ISO 27701. Both hold SOC 2 Type II, and both send privacy notices to the EU contacts in their databases.

ZoomInfo adds ISO 27017 and ISO 42001 plus a TRUSTe GDPR validation. It says removals complete within 48 to 72 hours.

Cognism says it regularly scrubs its data against 15 major do-not-call and TPS lists. They include lists for the UK, the US, Germany, France, Ireland and Spain. Cognism's comparison page puts the reach at 15 countries and credits ZoomInfo with "DNC list checking in 8 countries". ZoomInfo's own comparison page does not mention do-not-call screening.

Why that matters more in London than in Chicago comes down to two rules. In the UK, PECR bans unsolicited marketing calls to any number on the register. In the US, the FTC says most calls between a telemarketer and a business are exempt from the Telemarketing Sales Rule.

A US SDR team calling office lines rarely needs a screened list. A UK team calling mobiles always does, because the register covers corporate subscribers as well as individuals.

Cognism vs ZoomInfo: intent and workflow

This facet is where ZoomInfo pulls ahead. It is also the answer to what ZoomInfo offers that Cognism does not.

ZoomInfo calls its intent first-party. It tracks 4,500+ intent topics across 85M+ weekly signals. Its Copilot Advanced package bundles buyer intent signals, website visitors and "workflows for automated outreach". Streaming Intent is an add-on, and ZoomInfo also offers conversation intelligence.

Its visitor identification has a hard border. WebSight BuyerID, the person-level version, operates "exclusively in the United States", and ZoomInfo says GDPR markets are not in scope. A UK or German team gets no person-level visitor identification from it. Our buyer intent data guide explains how those signals get scored.

Cognism resells Bombora. Its Pro package includes Bombora Company Surge with up to 12 intent topics from a library of over 11,000. It tracks 20,000 technologies for technographic filters and has no website visitor identification. Integrations cover Salesforce two-way, HubSpot, Microsoft Dynamics, Pipedrive, Outreach, Salesloft and Bullhorn.

A team that already runs a sequencer and a visitor identification tool loses nothing with Cognism's thinner layer. A team that wants all of it in one contract buys ZoomInfo.

Cognism vs ZoomInfo: pricing

Is Cognism cheaper than ZoomInfo? Not per seat. The two medians in the quotes we heard sit $4 apart. The real differences are the seat floor and what a credit buys.

Neither vendor prints a price. Cognism's pricing page shows Standard and Pro, with 5 seats included in each. ZoomInfo's pricing page shows Professional, Copilot Advanced and Copilot Enterprise.

The lines below are prices heard on Spona's sales calls: what a buyer said they were quoted or paid. Each is one buyer's figure, never a list price, and the seat counts and units differ.

The denominators are small. ZoomInfo came up on 12 calls in Spona's first log and 11 in the second, with three figures each time. Cognism came up on 8 calls in the first log and 9 in the second, again with three figures each. The two logs overlap in time, so the counts cannot be added.

Per seat, the Cognism lines run from $2,639 to $4,900 a year. The ZoomInfo lines run from $2,773 to $6,000. The dearest ZoomInfo seat sits on the smallest line heard: Professional, 3 seats for $18,000.

The seat floor is the tie-breaker. Cognism's Standard and Pro each include 5 seats, so a team of four pays for one it will not fill. The smallest ZoomInfo line heard was a 3-seat quote. A small team that still wants a seat tool should also read our ZoomInfo vs Lusha comparison before signing.

What a credit buys differs more than the price does. At Cognism, one credit is one revealed contact. Viewing that contact again is free, and a credit is spent again only if the person changes jobs. At ZoomInfo, each export costs one credit, and packages hold a set number of credits.

Per included record, the Cognism lines run $0.48 to $0.98. The ZoomInfo lines run $0.70 to $1.80. That is indicative only. A reusable reveal and a one-off export are not the same unit.

All 12 lines are 12-month terms. Ten of them auto-renew, and eight carry a renewal uplift of 3% to 8.7%. Our Cognism pricing and ZoomInfo pricing posts walk through each package and its clauses.

Cognism vs ZoomInfo: what buyers said

Four more buyers, four sentences, from Spona's deal notes. Each is one person's words, anonymized to role, company size and country.

A UK founder at a company of 11 to 50 staff, who switched away from ZoomInfo: "We need a usable list each month, not another annual seat."

A US RevOps director at a company of 201 to 500 staff, still on ZoomInfo with renewal months away: "The extra contacts are useful, but we cannot change the contract this quarter."

A US VP of sales at a company of 51 to 200 staff, who kept ZoomInfo and added Spona: "We will keep our current workflow, but we need more people at regional accounts."

A French founder at a company of 11 to 50 staff, weighing Cognism: "Let us prove the segment with one list before committing to a larger contract."

Spona's win/loss records code every closed deal with one reason, and each reason carries the same recorded wording. When Spona won against Cognism, the most common line was: "We found the right people in the territory we actually sell to."

When Spona lost against ZoomInfo, the records hold two lines. One is "We are already committed to the incumbent for this budget period." The other is "Our team could not change its process during the migration." Every loss against Cognism carried one line: "We cannot add another paid workflow this quarter."

Most of the buyer quotes in this post turn on contract shape, not data quality. They name an annual seat, a renewal date and a workflow nobody wants to move. That is the gap a per-lead source fills.

Cognism vs ZoomInfo: Spona as a per-lead add-on

Spona is not a third database to weigh against these two. It fits three situations from the records above. The first is a campaign buyer who needs a list a month, and the second a team of one to four below Cognism's seat floor. The third is an incumbent whose coverage runs short in one territory.

You describe your ideal customer in a chat. The AI mines 40+ sources, verifies every lead and delivers a scored list in about 4 minutes. You pay per lead, in credits, and every search starts with a free sample.

The worked example below is our calculation on Spona's public prices. A Standard Search lead with email and mobile costs 35 to 55 credits. At the plan rates that is $0.28 to $0.55 a lead.

Each new search session costs a one-time 1,000 credits. That is $8 to $10, depending on the plan. Premium billed yearly costs $375 a month for 55,000 credits. That is $4,500 a year.

After one session fee, those credits buy roughly 980 to 1,540 such leads a month. That is a little more than the median seat at either vendor, spent on leads you pick by segment instead of a login you fill.

If you keep your current seats and only want the gaps filled, enrich your own list instead. That costs 5 credits for a verified email and 35 for a mobile. It is the pattern of the UK sales director and the US VP of sales above. The incumbent stays, and a per-lead source adds the missing accounts.

The limits are real. Spona has no website visitor identification. It sells no dialer, and AI calling is announced, not available. It makes no do-not-call screening claim, so a UK calling team keeps its own TPS and CTPS check.

Its only native CRM integration is HubSpot, on Premium and Expert. Salesforce takes a CSV import, and the API runs on Expert only. Cognism's hand-checked mobiles and ZoomInfo's intent stack both sit outside what Spona sells.

Cognism vs ZoomInfo FAQ

Is Cognism better than ZoomInfo?

Cognism is better for teams of five or more that mostly call UK and European mobiles. Its mobiles are checked by hand and screened against do-not-call registers in 15 countries. ZoomInfo is better for North American pipelines, and for teams that want intent, visitor identification and workflows in one contract. In the quotes heard on Spona's calls, the median seats sit about $4 apart, so where you sell decides, not price.

What do reviews say about Cognism vs ZoomInfo?

AiSDR reports G2 complaint counts for both tools. It lists 232 ZoomInfo reviews citing inaccurate data and another 232 citing outdated data. Cognism drew 91 on inaccurate data and 59 on wrong numbers. These are complaint counts, not an accuracy test, and our ZoomInfo reviews post covers the ZoomInfo complaints in detail.

Can you run Cognism and ZoomInfo together?

You can, but you then hold two 12-month contracts that mostly auto-renew. Two cheaper patterns show up in Spona's records. A UK team kept Cognism for calling and added a per-lead source for new target accounts. A US team kept ZoomInfo's workflow and added per-lead data for regional accounts.

If a third platform is on the table instead, our Apollo vs Cognism and ZoomInfo vs Apollo posts cover those pairs.

Do Cognism and ZoomInfo offer free trials?

ZoomInfo says you can start free on GTM.AI with no credit card. Cognism offers a free data sample rather than a trial login. Neither prints a price. The sample or the trial is the only way to test coverage on your own accounts before a 12-month term starts.
