ZoomInfo's agents run on the GTM Context Graph, so they reason across verified data, CRM history, intent, and conversation signals together. With Agent Teams in GTM Studio, a supervisor agent coordinates specialist agents through a full play, from spotting a signal to outreach and CRM updates. Teams can start from 50+ ready-made agents or describe a play in plain English, and see a credit estimate before each play runs.
In GTM Workspace, AI agents surface buying signals and draft outreach in context for each seller.
Demandbase Account Intelligence scores and prioritizes accounts from intent and firmographic signals, and that scoring stays within the Demandbase platform.
If your definition of ABM is tightly tied to account-based advertising and web personalization, Demandbase remains a strong choice. If it includes account selection, buyer signals, cross-channel activation, and sales follow-through, ZoomInfo is often the broader option.
ZoomInfo Marketing builds audiences using intent data, buyer signals, and account fit scoring, enriches and expands buying groups with verified contact data, and activates audiences across channels including native DSP, web, email, and sales workflows. ZoomInfo was named a Leader in the 2026 Gartner Magic Quadrant for Account-Based Marketing Platforms, its third consecutive year, and Smartsheet reported a 40%+ increase in form fills and 84% increase in MQLs using these tools.
Demandbase's intent model is closely tied to its advertising engine and account identification workflows, reporting 2T+ signals per month across 810K+ keywords in 133 languages. That makes it particularly useful when media activation is central to the strategy, though execution beyond advertising typically depends on external tools. For more on ABM software, see account-based selling software.
An all-in-one platform still has to connect to the rest of your stack, and to your AI tools.
ZoomInfo delivers the same data and intelligence wherever you work: in GTM Workspace or GTM Studio, inside Salesforce, HubSpot, and other native integrations, or headless through the API and MCP. The B2B data API and the ZoomInfo MCP server draw on the same verified data. ZoomInfo maintains ISO/IEC 27001, 27701, 27017 and 42001 certifications, SOC 2 Type II, the TRUSTe Responsible AI Certification, and TRUSTe GDPR and CCPA validations, published in its Trust Center.
Demandbase has no published MCP-based access, so its intelligence stays within its own platform.
