ZoomInfo's verified intelligence (100M companies, 500M contacts, billions of buying signals) now powers Nooks AI through GTM.AI, and Nooks engagement data flows back into ZoomInfo to enrich GTM Studio Audiences through a Custom Data Connector.
ZoomInfo (NASDAQ: GTM), the all-in-one AI GTM platform, today announced a two-way integration with Nooks AI, the AI sales platform best known for its parallel dialer. Mutual customers can now bring ZoomInfo into Nooks through a native connector, and they can enrich GTM Studio Audiences with their Nooks license by creating a Custom Data Connector. The connective tissue underneath both flows is GTM.AI, ZoomInfo's headless GTM context layer. GTM.AI exposes ZoomInfo's verified data graph and agentic orchestration through API and Model Context Protocol (MCP), so any platform, agent, or workflow can plug in. With this integration, Nooks customers get verified contact and account data inside the dialer, and ZoomInfo customers get Nooks engagement signals inside the audiences they build for outbound.
Key takeaways
Nooks AI is now a verified-data partner of ZoomInfo, with GTM.AI as the GTM Context Layer underneath the dialer and the GTM Studio Audience.
The integration runs in two directions. ZoomInfo data enters Nooks through a native connector. Nooks engagement data enters ZoomInfo through a Custom Data Connector that feeds GTM Studio Audiences.
GTM.AI is the headless GTM context layer. It powers dozens of completed integrations across CRMs, AI assistants, MCP-native agents, and sales engagement platforms, with the same governance applied everywhere.
The GTM Context Graph behind GTM.AI maintains identity-resolved data on 100M companies, 500M contacts, and billions of signals, continuously updated and continuously queryable.
What is Nooks AI?
Nooks AI is an AI sales platform built around an AI-powered parallel dialer, a coaching layer, and a virtual salesfloor. It is used by outbound sales teams to multiply the number of conversations a sales development representative can have per hour. Nooks dials multiple numbers in parallel, drops to voicemail automatically, and routes connected calls to a live rep. Reps spend less time on the dial and more time in conversations.
How does the Nooks AI and ZoomInfo integration work?
The integration runs both ways.
Direction one. ZoomInfo into Nooks. Mutual customers connect their ZoomInfo entitlement to Nooks through a native connector. Once connected, the Nooks dialer reads ZoomInfo contact and account data directly. Reps see verified phone numbers, firmographic context, and intent signals next to the dial. There is no separate enrichment pass, no CSV import, no broker layer.
Direction two. Nooks into ZoomInfo GTM Studio Audiences. Customers use their existing Nooks license to create a Custom Data Connector inside ZoomInfo's GTM Studio. The connector pulls Nooks engagement data (called, connected, talked, disposition, etc.) back into GTM Studio Audiences. Marketers and RevOps build audiences that include or exclude contacts based on what happened on the phone. The next campaign, the next outbound sequence, the next agent run uses that signal.
What is GTM.AI, and why is it the GTM Context Layer for Nooks?
GTM.AI is ZoomInfo's headless GTM context layer. It exposes ZoomInfo's verified data graph and agentic orchestration through API and Model Context Protocol (MCP), so any tool, agent, or platform can plug in. Nooks is one of dozens of completed integrations on GTM.AI, alongside Salesforce Agentforce, HubSpot Breeze, Microsoft Copilot, Gong, LeanData, Glean, Claude, ChatGPT, and Google Workspace.
GTM.AI has two layers and one governance plane. The bottom layer is the GTM Context Graph, which holds identity-resolved data on 100M companies, 500M contacts, and billions of signals. The middle layer is agentic orchestration, which lets agents read from the graph, act on it, and write back. The governance plane sits above both, applying access control, permissioning, data lineage, AI policy, and audit logging consistently across every surface that consumes GTM.AI. Nooks, GTM Studio, and any future agent the customer builds inherit the same governance posture.
Why does the data layer matter for an AI dialer?
About 70% of B2B contact data decays every year. A dialer that runs on stale data wastes the most expensive minute a sales team has, which is the minute a rep is on a connected call with the wrong person. Verified data turns that minute into a real conversation. GTM.AI is the difference between a dialer that produces pipeline and one that produces wrong numbers at machine scale. For outbound teams evaluating where verified data fits into their broader toolkit, the guide to AI sales prospecting tools covers how data quality affects every stage of the prospecting workflow.
The same argument runs in reverse for GTM Studio Audiences. An audience built from stale signal is an audience that wastes campaign spend. Pulling fresh Nooks engagement data through the Custom Data Connector keeps the audience aligned with what actually happened in the last call.
How is the Nooks-ZoomInfo integration different from a generic data integration?
Native, two-way, no broker. The native connector reads ZoomInfo entitlement directly. The Custom Data Connector pushes Nooks data back into GTM Studio Audiences directly. No middleware, no nightly sync, no broker tax.
Verified data layer through GTM.AI. Most dialer integrations rely on whatever data the customer brings. With GTM.AI as the data layer, Nooks reads from the GTM Context Graph, which is continuously refreshed and identity-resolved at the contact and account level.
Platform-level governance. Access control, data lineage, AI policy, and audit logging apply across both directions of the integration. Customers maintain one governance posture across ZoomInfo, Nooks, and any other surface that consumes GTM.AI.
What does this mean for sales and RevOps leaders?
Fewer wasted dials, more verified conversations. Reps dial against verified ZoomInfo data without leaving Nooks.
Closed-loop audiences. Marketers and RevOps build GTM Studio Audiences that respond to what happened on the call, then push the next campaign into Nooks against the updated audience.
One context layer across the GTM stack. ZoomInfo, Nooks, the CRM, and any AI agent the customer builds read from the same GTM Context Graph and write back under the same governance.

What signals can flow back from Nooks into GTM Studio Audiences? Engagement signals from the Nooks dialer, including call attempts, connects, conversation outcomes, and dispositions. Customers use those signals to build or refine GTM Studio Audiences.
How does GTM.AI handle governance for the Nooks integration? GTM.AI's platform layer applies access control, permissioning, data lineage, AI policy, and audit logging consistently across every surface that consumes it. Both directions of the Nooks integration inherit that posture, alongside ZoomInfo itself and every other GTM.AI integration.
Why does verified data matter for an AI dialer? B2B contact data decays at roughly 70% annually. A dialer running on stale data wastes the most expensive minute a sales team has, which is the connected-call minute. Verified, continuously refreshed data through the GTM Context Graph is the difference between a dialer that produces pipeline and one that produces noise.
