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the tab-switching, the manual enrichment, the nagging suspicion that the contact data you're working from is already out of date.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, the all-in-one AI GTM Platform, has spent more than 15 years building toward solving, and it's why we're excited about our role bringing ZoomInfo's verified B2B intelligence, through GTM.AI, our API and Model Context Protocol (MCP) server, directly into HubSpot's Breeze Prospecting Agent. Now in public beta (with a 28-day free trial), Breeze is powered by ZoomInfo's verified B2B intelligence. 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 ZoomInfo's selection as a HubSpot Breeze data provider means
ZoomInfo was selected as a third-party data provider for HubSpot's Breeze Prospecting Agent, now in public beta with a 28-day free trial. This is the ZoomInfo HubSpot integration that RevOps and sales teams have been asking about: verified B2B intelligence flowing natively into the HubSpot workflows your team already runs, without a separate tab, a CSV export, or a manual enrichment step.
Some context on how we got here. HubSpot acquired Clearbit in December 2023 and rebranded it as Breeze Intelligence, building a native data enrichment layer directly into HubSpot's CRM. ZoomInfo's selection as a HubSpot Breeze data provider signals that HubSpot is expanding its data ecosystem beyond its Clearbit roots, bringing in external prospecting-grade intelligence to power the Breeze Prospecting Agent's full-cycle workflow.
ZoomInfo and Breeze Intelligence are not alternatives. Breeze enriches contacts already inside HubSpot; ZoomInfo brings external prospecting data, buying signals, and the GTM Context Graph intelligence layer to identify and engage net-new accounts. ZoomInfo's selection makes this complementarity official and native, the two tools now work as a stack, not a choice.
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.
That intelligence runs through ZoomInfo's GTM Context Graph, the reasoning layer that processes 1.5B+ data points daily, fusing B2B contact data with CRM records, conversation intelligence, and behavioral signals to surface not just who to contact but why they are likely to engage.
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 data coverage brings to the Breeze workflow:
500M+ contacts with current roles, employment history, and direct contact details
100M+ 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 and news alerts, champion movement, earnings, call transcripts, and funding events
210M+ 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. Forrester named ZoomInfo a Leader in Intent Data Providers, citing the largest R&D investment of any provider in the space.
One capability worth calling out specifically in the HubSpot context: ZoomInfo's Scoops. When ZoomInfo detects that a target account has raised a funding round or made a leadership change, HubSpot can auto-enroll that contact in a timely outreach sequence. This is a trigger-based prospecting capability that Breeze Intelligence does not replicate natively, and it's one of the clearest examples of what external intelligence adds to a HubSpot-native workflow.
How GTM.AI connects ZoomInfo intelligence to any AI workflow
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.
For teams already running HubSpot Sequences, ZoomInfo's selection as a Breeze data provider means enrichment and signal data flow natively into HubSpot, your existing sequencing workflows stay intact, now grounded in continuously refreshed intelligence.
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

Why data quality is the bottleneck for agentic AI
Research from Salesforce's State of Sales report finds 91% of CRM data is incomplete or inaccurate. 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 HubSpot users, this means Breeze Prospecting Agent is only as effective as the data feeding it, which is precisely why ZoomInfo's selection as its data provider matters.
ZoomInfo vs. Breeze Intelligence: complementary, not competing
ZoomInfo and Breeze Intelligence serve different functions in the same stack. ZoomInfo provides external prospecting data and buying signals; Breeze Intelligence enriches contacts already inside HubSpot using its native data layer. ZoomInfo's selection as a Breeze data provider makes the two tools a native stack rather than a choice between them, the ZoomInfo HubSpot integration is additive by design.
Capability | ZoomInfo (via Breeze) | Breeze Intelligence (native) |
|---|---|---|
Data source type | External B2B database (500M+ contacts, 100M+ companies) | HubSpot-native enrichment layer |
Intent signals | ZoomInfo buying signals, Scoops, and company event alerts | Breeze website visitor intent |
HubSpot integration depth | Selected third-party data provider | Native |
Best for | Outbound prospecting and enrichment of net-new accounts | Inbound enrichment of contacts already in HubSpot |
Enrichment trigger | Real-time via GTM.AI | Batch or on-demand |
ZoomInfo holds 133 No. 1 G2 rankings, including in Data Quality and Account Data Management, third-party validation of the data foundation that makes the Breeze integration meaningful rather than incremental.
If your team runs outbound sequences and needs external prospecting data, ZoomInfo as Breeze data provider adds significant value on top of Breeze's native enrichment. If your motion is primarily inbound and HubSpot-native, Breeze alone may suffice for enrichment. Most teams running a full-funnel motion benefit from both.
ZoomInfo is certified SOC 2 Type II, ISO 27001, and ISO 27701, and is compliant with GDPR and CCPA. Data flowing into HubSpot via Breeze is subject to ZoomInfo's compliance framework, which matters for enterprise procurement teams and EMEA-based organizations with strict data residency requirements.

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. For RevOps teams, the practical implication is straightforward: the enrichment infrastructure you've been managing across multiple vendors now has a cleaner path to consolidation, with governance and entitlements that hold across every workflow the Breeze agent runs.
