The Trust Layer: Dun & Bradstreet Grounds Microsoft's AI in Reality

JACKSONVILLE, FL – June 02, 2026 – In the rapidly expanding universe of enterprise artificial intelligence, the most urgent conversations have shifted from generative wonder to the bedrock of reliability. Today, Dun & Bradstreet, a name synonymous with business data for over 180 years, announced a move that directly addresses AI's nagging trust problem. By integrating a curated sample of its verified business data directly into Microsoft 365 Copilot, the company is providing a crucial dose of reality for AI-powered workflows.

This partnership, unveiled as the Dun & Bradstreet Graph Connector for Microsoft 365 Copilot, gives developers and enterprises no-cost access to foundational data on tens of thousands of global companies. While the initial promise of AI assistants was their ability to fluently summarize and create, their Achilles' heel has been a tendency to “hallucinate”—generating plausible but incorrect information. This integration represents a strategic bet from both Microsoft and Dun & Bradstreet that the future of enterprise AI isn't just about better algorithms, but about better, verifiable data.

Grounding AI in Commercial Reality

The core of the announcement is the Graph Connector, a technical bridge that allows D&B's vast Commercial Graph to feed directly into the Microsoft Graph that powers Copilot. Instead of relying solely on an organization's internal, and often messy, data—a mix of emails, CRM notes, and stray documents—Copilot can now query a clean, structured source of truth for commercial identity.

This “curated sample” includes essential information like company summaries, locations, contact details, and ranges for employee counts and annual revenue. For any business professional, the value is immediately clear. AI failures often begin with a simple case of mistaken identity: confusing a subsidiary with its parent, citing a long-closed office, or targeting a similarly named but entirely different firm. By grounding its responses in D&B's verified data, anchored by the globally recognized D-U-N-S® Number system, Copilot can begin to avoid these expensive errors.

"As organizations accelerate their adoption of AI, access to verified, well-structured data is essential to achieving meaningful outcomes," said Gary Kotovets, Chief Data and Analytics Officer at Dun & Bradstreet. "By embedding a curated sample of our verified commercial data directly into Microsoft 365 Copilot, Graph Connector lowers the barrier for developers and enterprises to start building with AI, making it easier to incorporate verified data into workflows and applications from day one."

A Strategic Evolution for Productivity Tools

This integration is more than a simple data feature; it signals a strategic evolution for Microsoft 365 Copilot itself. The tool is transforming from a sophisticated language assistant into a genuine business intelligence partner. The ability to not just generate a report, but to ensure the companies mentioned in that report are correctly identified and contextualized, is a significant leap in value.

"Knowing who you're doing business with is an essential part of knowledge workflows," noted Chantrelle Nielsen, Principal Product Management for Microsoft 365 Copilot at Microsoft. "Integrating this sample of Dun & Bradstreet data into Microsoft 365 Copilot provides that crucial first step of business identification and opens the door for users to explore new ways to use D&B's continuously updated business data in Copilot."

This shift improves the user experience by embedding trust directly into the workflow. An interactive display of verified company data, complete with trust badges, allows a user to see not just what Copilot says, but why it can be trusted. For Microsoft, this deepens the value proposition of its entire 365 ecosystem, making it an even more indispensable platform for modern work by directly tackling one of its customers' biggest pain points with AI.

From Exploration to Enterprise-Scale Innovation

The most strategic element of this launch may be its accessibility. By offering a substantial sample at no cost, the partners are effectively opening the gates for a new wave of innovation. Startups, small businesses, and individual developers can now experiment with enterprise-grade business data that was previously out of reach, exploring AI-driven use cases in sales, market research, and supply chain management.

This “freemium” approach serves as a powerful on-ramp. An organization can begin by leveraging the free data for exploratory tasks, such as having a sales team use Copilot to get quick, verified summaries of prospective clients before a call. A procurement manager can use it to generate an initial list of potential suppliers in a new region, confident in their identities.

Once the value is proven, the path to deeper integration is clear. Because the connector is built on the same D&B Commercial Graph used for enterprise-level risk and compliance, scaling up is a natural next step. A financial institution, after seeing the benefit of basic identity verification, can upgrade to access D&B's full suite of credit risk and compliance data for more rigorous due diligence, all within the same ecosystem. This model allows businesses to start small, prove the ROI, and scale their AI initiatives with confidence.

Building the Foundation for Trustworthy AI

This partnership lands at a critical moment in the development of artificial intelligence. Industry analysts have been vocal that the long-term success of enterprise AI will be judged not by its novelty, but by its reliability and accuracy. The problem of “garbage in, garbage out” is a fundamental constraint, and solutions that provide clean, verified data are becoming immensely valuable.

By embedding a verified identity layer into one of the world's most widely used productivity suites, Microsoft and Dun & Bradstreet are demonstrating a commitment to building a more responsible AI framework. This move strengthens the competitive positions of both companies, positioning D&B as a foundational data provider for the AI era and Microsoft as a leader in delivering practical, grounded AI solutions that enterprises can actually depend on.

As AI continues to weave itself into the fabric of daily business operations, the ability to ask a simple question—"Who is this company, really?"—and receive a verified, trustworthy answer will be the cornerstone of lasting value. This integration is a significant step in building that foundation.
