Cognism vs GTM Workspace by ZoomInfo (2026)
Cognism sells European contact data that is screened and verified before a rep sees it, while GTM Workspace is ZoomInfo's seller workspace that turns its data and signals into account briefs and next steps inside the CRM. Cognism is a London based data provider with phone verified mobile numbers, Do Not Call and TPS screening, European data kept in the EEA by default, and delivery through a prospecting platform, CRM enrichment, an API and an MCP server. GTM Workspace sits on Salesforce, HubSpot or Microsoft Dynamics and combines ZoomInfo's database, intent and job change signals with CRM history and call transcripts, then drafts briefs, emails and CRM updates. Cognism's buyer is a sales or revenue operations leader prospecting into Europe who needs clean numbers to dial. GTM Workspace's buyer is a revenue leader already standardized on ZoomInfo who wants sellers to work accounts in one place. Neither publishes a price. Choose Cognism when European coverage and calling compliance decide the deal. Choose GTM Workspace when the data source is settled and the goal is seller productivity across a global book.
- Your pipeline is in Europe, and you want European data kept inside the EEA by default, with the site and support in English, German and French.
- Your reps dial, and phone numbers should arrive already screened against Do Not Call and TPS registers, with phone verified mobiles on the Pro package.
- You want the people in your data told about it, since Cognism notifies business contacts that it holds their details and runs an opt out portal and a toll free rights line.
- You need the data inside your own tools, through CRM Enrichment that keeps records current, an API, or an MCP server that lets Claude or ChatGPT query Cognism directly.
- A revealed contact should stay paid for, with no new credit spent until the person changes jobs.
- Your company already runs on ZoomInfo data, and sellers need one place to research, prioritize and act on accounts.
- You want signals routed to reps, with Pulse Feed sending up to 1,000 a day across more than 15 types such as intent, job changes, funding and hiring.
- Sellers should get meeting briefs, deal reports and outreach drafts built from CRM history, call transcripts and ZoomInfo data, with sources cited.
- Your CRM is Salesforce, HubSpot or Microsoft Dynamics, and updates from calls should write back automatically with CRM permissions intact.
- You sell globally and want a public company vendor with more than 35,000 customers and named results from Seismic, MongoDB and Thomson Reuters.

The short version of each
Cognism
Cognism is a B2B contact and company data provider based in London and founded in 2015, built around European coverage and compliance. Records carry firmographic, technographic and signal filters, director level data is refreshed every 30 days, and the Pro package adds phone verified mobiles with on demand verification and Bombora intent data. Phone numbers are screened against Do Not Call and TPS registers before delivery, European data stays inside the EEA by default, and people in the database are told that Cognism holds their details. Data arrives through a prospecting platform, CRM Enrichment, an API and an MCP server for AI assistants. Cognism holds ISO 27001, ISO 27701 and SOC 2 Type II, and more than 4,000 companies use it, with DinMo reporting fourfold ARR growth in six months. Cognism's GTM Tech Index profile sets out its credit rules, which count a contact once until the person changes jobs. The main caveat is price, since neither the Standard nor the Pro package carries a published figure.

GTM Workspace by ZoomInfo
GTM Workspace is ZoomInfo's seller workspace, a layer that sits on Salesforce, HubSpot or Microsoft Dynamics and syncs both ways in real time. It merges CRM records, call transcripts and email history with ZoomInfo's contact and company data and its signals for intent, job changes, funding and hiring. Pulse Feed routes those signals to the right rep, AI Chat answers account questions with citations, AI Docs drafts briefs and outreach that send through Gmail, Outlook, Outreach or Salesloft, and Views push call updates back to the CRM. ZoomInfo is a public company with more than 35,000 customers, and Seismic attributes 39% of its pipeline to ZoomInfo signals. The product states SOC 2 Type II, tenant isolation for AI and model training on aggregated patterns only. Read beside Cognism on the GTM Tech Index, its main caveats are a quote only price tied to a ZoomInfo data subscription and no published rules for the calls and emails its users send.

Cognism keeps data about people in Europe inside the European Economic Area by default, moves the minimum under the Standard Contractual Clauses when it must, notifies people that it holds their data and publishes its site in English, German and French. GTM Workspace states GDPR and CCPA compliance, and ZoomInfo runs verified portals where people can see, correct or remove their records, but its product and pricing pages name no hosting region or residency option.

Do Cognism and ZoomInfo screen phone numbers against Do Not Call lists?
Cognism screens its phone data against Do Not Call and TPS registers before delivery, across the UK, the US, Germany, France, Australia and other named countries, so a registered number does not reach the rep. ZoomInfo's plans include intelligent dialing, and its public pages name no Do Not Call screening or calling rule for that feature, which leaves screening to the buyer.

GTM Workspace states SOC 2 Type II, full audit logging, tenant isolation for AI processing and model training on aggregated patterns rather than any one customer's data. Both encrypt data in transit and at rest. Graded by GTM Tech Index against seventeen capability axes from each vendor's own published materials, verified November 3, 2026.

Neither vendor publishes a price, and neither says what a customer may keep from revealed or exported records once the contract ends. Cognism does not name the provider behind its AI features or say whether enrichment data trains them, and it does not describe how its community sourced data is collected. ZoomInfo does not name a hosting region for GTM Workspace, publishes no calling or email rules for its dialer and outreach tools, and gives no figure for integration fees or credits.
GTM Workspace runs on a ZoomInfo data subscription, so it is not bought on its own. Ask Cognism what license covers revealed records after termination and what its community data collects. Ask ZoomInfo where GTM Workspace data is hosted and how its dialer handles Do Not Call rules.
