Cognism vs GTM Workspace by ZoomInfo (2026)
The decision is where your buyers sit and who screens a number before your team dials it. Cognism is the European specialist. It keeps European data inside the European Economic Area by default, screens its phone data against preference registers in twelve named jurisdictions before a number ever reaches a customer, and notifies people that it holds their data within the statutory timeframe, which is why the GTM Tech Index grades it A on outreach compliance and B on residency. ZoomInfo sells GTM Workspace above the largest and most commercially established contact database in this market, with the deepest outcome evidence and ecosystem in the index. It also ships a dialer and automated outreach while naming no calling or email rule anywhere, and it states no hosting region. An independent test across two hundred accounts put Cognism first in its cohort on European email accuracy and mobile connect rates, and reviewers describe its data outside Europe as competitive rather than differentiated, a limit the vendor never states itself. Both answer the person in the database at the top band. Neither publishes a price.
- Your pipeline is in Europe. Cognism keeps European data inside the European Economic Area by default and moves the minimum under standard contractual clauses when it must, publishes its site in English, German and French, and an independent test across two hundred accounts put it first in its cohort on European email accuracy near ninety one percent and mobile connect rates near eighty seven percent.
- Your team dials. Cognism screens phone data against preference registers in twelve named jurisdictions, including both United Kingdom registers, the United States, Germany, France and Australia, so a registered number never reaches your rep, and it states plainly that each party remains an independent controller responsible for its own outreach.
- You want the person in the database told. Cognism notifies business contacts that it holds their data within the statutory timeframe, names legitimate interest to the article with the supporting assessments carried out, is registered as a data broker with a United States state regulator, and runs a toll free rights line beside a dedicated opt out portal.
- You sell well beyond Europe. Reviewers describe Cognism's data outside Europe as competitive rather than differentiated, while ZoomInfo sells the largest contact database in this market and publishes customer evidence running from the largest technology companies in the world down to a video production firm and a small advisory practice.
- The records should flow into your own stack and your own agents. ZoomInfo delivers data into customer warehouses and analytics platforms through interfaces, webhooks and cloud data shares, keeps a separate developer domain, and sells Model Context Protocol support as a named product, where Cognism's interface access requires a prospecting seat.
- Provenance has to answer for each person. ZoomInfo names four source classes, including an employed research team and a named community contribution program, and its personal information notice tells each subject where their information was obtained, while Cognism describes its community sourced layer without the collection mechanism or the consent behind it.

The short version of each
Cognism
Cognism is a London based business contact and company database founded in 2015, selling prospecting, customer record enrichment and data delivery by interface or bulk file, with human verified mobile numbers as its differentiating asset. The GTM Tech Index grades it A on outreach compliance, where it screens telephone data against preference registers in twelve named jurisdictions before delivery and still tells buyers that its screening does not make their outreach lawful, and A on data privacy, where it names its lawful basis to the article and notifies people that it holds their data within the statutory timeframe. It takes B on eight more axes, including residency, where European data stays inside the European Economic Area by default, and security, with the information security and privacy management standards certified and a SOC 2 Type II attestation held. It grades D on commercial transparency, explaining its credit mechanic in full without a single price, and C on stewardship, with nothing published on whether enrichment data trains any model.

GTM Workspace by ZoomInfo
GTM Workspace by ZoomInfo is the command center ZoomInfo sells above the largest and most commercially established business contact database in this market, assembling contacts, intent, website visitors, job changes and engagement history into account timelines with assistive agents on top. ZoomInfo Technologies is publicly listed, so its customer numbers and revenue are filed rather than asserted. The GTM Tech Index grades it A on four axes: outcome evidence, data privacy, where four verified request workflows run on a dedicated subdomain, data licensing, where four source classes are named and each person's notice states where their information came from, and ecosystem depth, where Model Context Protocol support is sold as a named product. It takes B on security, recipient disclosure, segment coverage and platform terms. It grades D on commercial transparency, documenting six packages and their credit allowances without a currency figure, and C on outreach compliance, naming no sending or calling rule although the platform ships a dialer and automated outreach.

Common questions
Is Cognism better than ZoomInfo?
It depends on where you sell and who carries the calling risk. Cognism grades A on outreach compliance and B on residency in the GTM Tech Index, screens phone data against preference registers in twelve jurisdictions and keeps European data in the European Economic Area by default. ZoomInfo's GTM Workspace grades A on outcome evidence, data licensing and ecosystem depth, and sits above the largest contact database in this market. Both grade A on data privacy, so privacy handling is not what separates them.
Is Cognism or ZoomInfo better for European data?
Cognism, on everything either vendor publishes. It keeps European data inside the European Economic Area by default, publishes in English, German and French, and an independent test across two hundred accounts put it first in its cohort on European email accuracy near ninety one percent and mobile connect rates near eighty seven percent. ZoomInfo states no hosting region and no residency option, and the only geography it publishes is its own headquarters. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified September 27, 2026. No vendor pays for placement.
Do Cognism and ZoomInfo screen numbers against do not call registers?
Cognism does, before delivery. It names twelve jurisdictions, including both United Kingdom registers for consumer and corporate numbers, the United States, Germany, France, Australia and Sweden, so a registered number never reaches the customer to be dialed. ZoomInfo publishes no do not call position attached to its dialing feature, so on its public surface screening remains the buyer's job. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified September 27, 2026. No vendor pays for placement.
How much do Cognism and ZoomInfo cost?
Neither publishes a price, and both grade D on commercial transparency. Cognism names two prospecting packages with five seats each and explains its credit rules precisely: one credit reveals one contact, viewing it again is free, and credit is spent again only when the contact changes jobs. Third party procurement reporting places its entry package near fifteen hundred dollars per user a year plus a platform fee. ZoomInfo documents six packages, credit allowances of seventy five thousand and one hundred and fifty thousand on two of them, and a minimum bulk credit purchase for pre packaged integrations. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified September 27, 2026. No vendor pays for placement.
How does the GTM Tech Index grade Cognism and GTM Workspace by ZoomInfo?
Both are graded on the same seventeen capability and compliance axes from public sources, at a documented depth of sixteen each. Cognism takes A on data privacy and outreach compliance and B on eight more. GTM Workspace takes A on outcome evidence, data privacy, data licensing and ecosystem depth and B on four more. Both grade D on commercial transparency and C on stewardship, model transparency and exit. The index publishes no composite score and declares no winner.

The shared silence is the end of the license. Both sell records that are licensed rather than owned, and neither says what a customer may keep once the contract ends. Cognism states that a redeemed contact can be used throughout the contract and stops there. ZoomInfo meters export by credit and publishes nothing on post termination retention, on deletion, or on whether records delivered into a customer's warehouse must be purged when the license lapses.
For a data purchase that is the most consequential exit question, and it grades both C. The second shared silence is the model. Neither names a provider behind its AI features, and neither states whether customer records sent for enrichment train or tune any model. One exposure belongs here rather than in the verdict. ZoomInfo ships dialing and automated outreach and names no calling or email statute, consent standard or do not call obligation on its public surface.
The benign reading is that part of its sending surface routes to a named partner platform and the obligations sit in contracts. Ask both in writing what license attaches to revealed records after termination, and ask Cognism which trust criteria its current SOC 2 report covers, since one page claims all five and the same page later names two.
