Ask any sales or marketing team what slows them down most, and the answer is rarely a lack of effort. It's the friction (the tab-switching, the manual enrichment, the nagging suspicion that the contact data you're working from is already out of date). For years, the GTM stack has been a collection of tools that are good at different things but rarely talk to each other well enough to act as one.
That's changing fast. AI-powered prospecting agents are emerging that can handle the full prospecting cycle, from identifying the right accounts to sourcing contacts to executing outreach, without a human touching every step. But there's a catch: an AI agent is only as good as the data it runs on.
That's the problem ZoomInfo has spent more than 15 years building toward solving, and it's why we're excited about our new role as a data provider for HubSpot's Breeze Prospecting Agent. Now in public beta (with a 28-day free trial), Breeze is powered by ZoomInfo's verified B2B intelligence through GTM.AI, our API and Model Context Protocol (MCP) home for AI agents. The result is a full-cycle prospecting workflow where every decision the agent makes is grounded in real-time, continuously refreshed data, without your team ever having to leave HubSpot to get it.
What the Integration Actually Does
HubSpot's Breeze Prospecting Agent handles the entire prospecting cycle, identifying target accounts, sourcing the right contacts, and executing personalized outreach. With ZoomInfo selected as its data provider, every step of that cycle is now grounded in real-time, continuously refreshed B2B intelligence.
For HubSpot users with ZoomInfo accounts, this means the agent isn't operating from stale data or scraped records. It's drawing on ZoomInfo's verified database, without switching tabs, without exporting CSVs, and without any of the manual overhead that typically comes with enrichment at scale.
The Data Behind the Agent
The reason agentic prospecting can move from promising to production-ready is the quality of the data underneath it. Here is what ZoomInfo brings to the Breeze workflow:
500M+ professional profiles spanning the Americas, Asia, Europe, and Africa
250M+ company records with firmographics, technographics, and corporate hierarchy
500M+ contact records with current roles, employment history, mobile direct dials, and board memberships
Billions of buying signals — intent activity, Scoops & news, champion movement, earnings, call transcripts, and funding events
200M+ IP-to-organization pairings for deterministic identity resolution
But the real differentiator isn't the scale, it's how the data is connected. ZoomInfo's database isn't a flat list of tables. It's a graph. Every record resolves to every other record, meaning that when Breeze identifies a target account, it can simultaneously surface the right buying committee members, their direct contact details, the most relevant buying signals, and the context needed for personalized outreach all in a single workflow step.
That data is verified through a rigorous multi-source methodology: proprietary collection technology, machine learning, public-source signal processing, and a contributory network that continuously refreshes what ZoomInfo knows. Independent analysts have taken notice Forrester named ZoomInfo a Leader in Intent Data Providers, citing the largest R&D investment of any provider in the space.
Why GTM.AI Changes Everything
The HubSpot integration runs on GTM.AI, ZoomInfo's API and Model Context Protocol (MCP) server that's purpose-built for the agentic era. Through a single connective layer, any AI workflow can access ZoomInfo's verified intelligence with the same governance, the same entitlements, and the same continuously updated context graph underneath it.
That's a meaningful architectural shift. The same data that powers Breeze today can equally power a custom RevOps workflow, a forecasting model, or a vertical-specific sales motion tomorrow. As more platforms adopt agentic architectures, the bottleneck stops being model intelligence and becomes data quality. GTM.AI is the structural answer to that problem.
What GTM.AI enables:
Access ZoomInfo verified data through a single API-powered MCP server
Ground any AI agent in real-time, continuously refreshed B2B intelligence
Apply consistent governance and entitlements across every workflow
Connect to partner-built agents, in-house tools, or general-purpose AI assistants
Power full-cycle prospecting from account identification to personalized outreach
The Decay Problem, and Why It's Now Mission-Critical
Industry estimates suggest roughly 70% of B2B contact data decays every year. That was already a serious problem in the manual prospecting era. In the agentic era, it is fatal: an AI agent acting on stale data doesn't just produce one bad outcome, it produces bad outcomes at machine speed and scale.
This is why enrichment is no longer a back-office function or a quarterly data cleanup project. It is the foundation that determines whether an agentic workflow actually drives pipeline, or simply generates motion. Verified, continuously refreshed data is what allows an agent to move from "here is a list of accounts" to "here is the right contact, at the right company, with the right message, at the right moment."
For sales and marketing teams using HubSpot's Breeze Prospecting Agent, the impact is direct. The agent handles the heavy lifting. ZoomInfo, through GTM.AI, ensures every decision it makes is grounded in the most accurate, complete, and current B2B intelligence available, so your team can stop hunting for information and start having conversations that convert.
What This Means for Revenue Teams
This integration is an early, high-visibility signal of a broader shift underway. As AI reshapes how revenue teams operate, the platforms that win will be those built on verified data, not because accuracy is a nice-to-have, but because the cost of inaccuracy compounds with every autonomous action an agent takes.
ZoomInfo's selection as HubSpot's data provider for Breeze reflects the strength of that foundation, and the role GTM.AI plays in making it universally accessible across the GTM stack.
