What Harmon.ie does

harmon.ie is a privately held, Boston-based software company that develops email and document management add-ins for the Microsoft 365 ecosystem, primarily serving large enterprise and government customers in verticals such as government, finance and insurance, legal, construction, and manufacturing. Its product suite centers on two complementary offerings: New harmon.ie, a modern Outlook add-in supporting new Outlook, Outlook on the Web, and Outlook for Mac with integration to SharePoint Online, Teams, and OneDrive; and harmon.ie Classic, a COM add-in for Outlook for Windows (classic) that additionally supports SharePoint on-premises for hybrid deployments. An accompanying Windows desktop application provides a file-explorer-style interface for managing Microsoft 365 content without a browser. Core technical capabilities include intelligent metadata classification that auto-maps email headers to SharePoint columns, automatic capture of entire email threads for compliance, drag-and-drop and save-on-send filing flows, centralized enterprise administration via Microsoft 365 Admin Center and Microsoft Intune, and a 2025 beta for email automation with rule suggestion. Data never leaves the customer's Microsoft 365 tenant, and the product is ISO 27001 certified, GDPR/CCPA compliant, and supports Microsoft GCC and GCC High environments.

The company operates a quote-based, annual subscription licensing model with freemium 21-day self-serve trials and enterprise-assisted multi-user trials. Distribution combines direct enterprise field sales, a Microsoft Marketplace listing, and a channel partner program for resellers and system integrators. Reported scale metrics include 1,600+ enterprise customers worldwide, 23M+ emails saved to Microsoft 365 annually, and 92% customer satisfaction with support. Named customers span global enterprises and public-sector bodies (Bosch, Daimler, EY, BearingPoint, Babcock, Vinci Energies, Canada Post, ESDC, CSIRO, EASA), and harmon.ie holds Microsoft Trusted Gold Partner and Microsoft Preferred Content AI designations. Leadership includes co-founder and CEO Yaacov Cohen, Chief Product Officer David Lavenda, and VP of Growth Menachem Pritzker.
