Boris Feldman

I'm a product and engineering leader with deep experience building Microsoft-scale platforms spanning cloud services, real-time collaboration, and AI-native productivity experiences. Throughout my career, I have focused on how people collaborate—from document discovery and coauthoring to open-source collaborative platforms and emerging human-agent workspaces.

Over more than two decades at Microsoft, I have led strategy and execution for technologies used across Microsoft, most recently leading Fluid Framework and the evolution of collaborative canvases for Microsoft 365 and Copilot.

Outside of Microsoft, I have founded companies, contributed to industry publications, and hold patents spanning collaboration, payments, and web platforms.
