Glean

Glean is an enterprise AI platform that connects to 250+ company applications, securely indexes their data with permission-aware access, and uses that context to power enterprise search, an AI assistant, content creation, and custom AI agents. It's built for large enterprises and cross-functional teams (engineering, sales, IT, HR, legal, and more) that need AI grounded in their own tools and data. Its main differentiator is the unified, permission-aware enterprise knowledge layer plus model routing and governance controls that reduce token spend while keeping answers secure and explainable.
