Glean

Glean is an enterprise AI platform that connects to all the applications a company uses, such as Google Workspace, Slack, Jira, Confluence, GitHub, Salesforce, and dozens more, and builds a unified search index and knowledge graph over that content, respecting each system's permissions so people only see what they are allowed to. On top of that foundation it provides company-wide search that returns results across every connected tool from one box, and an AI assistant that answers questions in natural language grounded in the organization's own documents, messages, and tickets, with citations. Glean has expanded into an agent platform, letting teams build and deploy AI agents that carry out multi-step work using company knowledge and actions in connected systems, and it offers prebuilt assistants for engineering, sales, support, and other functions. It is positioned as a horizontal alternative to building on a single vendor's copilot, and it has grown quickly, passing two hundred million dollars in annual recurring revenue at a valuation above seven billion dollars. Glean is sold as a paid enterprise platform, priced per user per month with additional charges for agent and platform usage, and it is deployed with security reviews and data-residency options for large organizations.
