About This Dataset
The Companies Using Microsoft 365 database covers 175,544 verified companies across North America that are active Microsoft 365 subscribers — companies using M365 Business Basic, Business Standard, Business Premium, Enterprise E3, or Enterprise E5 as their primary productivity, email, and collaboration platform.
Every record identifies the Microsoft 365 decision-maker or administrator — IT Manager, Office Admin, CTO, VP of IT, or CEO — with a confirmed work email, LinkedIn URL, M365 plan tier, primary Microsoft 365 workloads in use (Teams, SharePoint, Exchange, Intune, Defender), company size, and full company profile.
Microsoft 365 is the single largest technology platform in the world by company count — making this the broadest technographic signal in the B2B technology market. The install base spans every industry, company size, and geography, creating targeting opportunities for virtually any enterprise software vendor.
This is the foundational database for Microsoft partner network vendors, Teams app developers, SharePoint consultants, Microsoft 365 migration service providers, and security vendors protecting the Microsoft stack. Updated quarterly with 95%+ email deliverability.
