Head-to-head
ZoomInfo vs Cognism: which one in 2026?
ZoomInfo is a go-to-market data and workflow platform from ZoomInfo Technologies LLC, and Cognism is a prospecting data product from Cognism Ltd built around phone-verified contacts. The main difference is breadth: ZoomInfo bundles sales, marketing and AI agent tooling in tiers, while Cognism sells two seat-based plans centered on contact data.
Verdict
ZoomInfo is the stronger pick for a team that wants prospecting data, intent, marketing audiences and AI agents under one contract, and it is ranked above Cognism for that reach. Cognism is the tighter fit for outbound teams that care about verified mobiles and a short plan list. Neither publishes prices, so ask both for a quote that states seats, credits and the intent topics you actually need.
ZoomInfo and Cognism side by side
| ZoomInfo | Cognism | |
|---|---|---|
| Price entry | Quoted | Quoted |
| How each is sold | Consumption-based on credits, with Professional, Copilot Advanced and Copilot Enterprise tiers for sales and separate marketing plans. Most are quote only. | Two plans, Standard and Pro, each with 5 seats included. Pricing is described as tailored to the product, with no figures on the page. |
| Free access | The homepage names a permanent free plan, ZoomInfo Lite, and the pricing page offers trials on Professional and the Copilot plans. | No free plan or trial is stated. The footer links to a free data sample, which the page does not describe as a plan. |
| Intent data | Intent signals start at Copilot Advanced. Marketing plans cap intent topics at 25 on Demand, 100 on ABM Lite and unlimited on ABM Enterprise. | Bombora-sourced buying intent comes with the Pro plan only, with up to 12 topics selectable. |
| Phone data focus | Professional lists direct-dial and email data among its inclusions, with no statement on verification method or refresh cadence. | Mobile numbers are phone-verified, with a vendor claim of up to 3x higher connect rates. Director-level and above data is refreshed every 30 days. |
| AI features | GTM Workspace with agents for account research and meeting prep, Agent Teams working within approvals you set, plus AI email drafting on Professional. | AI account research and search refinement on both plans, and a data fusion engine that the FAQ says combines sources before verification. |
| Connecting to AI assistants | An MCP server links Claude, ChatGPT and custom agents to ZoomInfo data, and GTM.AI offers headless API, CLI and MCP access. | MCP and API access, marked new, sits on Standard and runs under the same permission and compliance settings as the app. |
| Security statements | The privacy policy names SOC II, ISO 27701 and ISO 27001, and EU-US and Swiss-US Data Privacy Framework participation. Hosting is US and other countries. | The homepage claims GDPR and CCPA compliance and alignment with ISO 27001 and SOC 2. The privacy and trust pages returned errors and were not read. |
| Credit mechanics | Plans draw on credits, for example 75K on Marketing Demand and 150K on ABM Enterprise. Sales plan allowances were not shown. | One credit reveals one contact, already-revealed contacts cost nothing to view, and credits work across prospecting, Enrich and the API. |

Frequently asked questions
Does Cognism or ZoomInfo have a free plan?
ZoomInfo does. Its homepage names a permanent free plan called ZoomInfo Lite, and the pricing page offers trials on Professional and Copilot. Cognism states no free plan or trial on the pages checked, only a link to a free data sample. Confirm current terms with each vendor before relying on either.
Which gives better phone numbers for cold calling?
Cognism puts phone verification at the front, with phone-verified mobiles, on-demand mobile verification on Pro and a vendor claim of up to 3x higher connect rates. ZoomInfo lists direct-dial data on Professional without describing verification. The claim is the vendor's own, so test a sample list against your region.
Can I use ZoomInfo or Cognism data inside Claude or ChatGPT?
Yes for both, through MCP. ZoomInfo runs an MCP server for Claude, ChatGPT and custom agents, and Cognism offers MCP and API access that follows the same permissions and compliance settings as the app. Check which plan unlocks it for you, since Cognism lists it on Standard.
Do ZoomInfo and Cognism train AI models on my data?
The pages checked do not say. ZoomInfo's privacy policy lists fine-tuning or training models among uses of data without addressing customer data, and Cognism's privacy and trust pages could not be read. Ask each for a written statement on AI training, retention periods and hosting region before signing.
