Glean

Glean is an enterprise AI platform that indexes and searches across a company's entire corpus of internal data — documents, emails, chats, tickets, wikis, and more — using deep learning and a company-specific knowledge graph. Founded by ex-Google search infrastructure engineers, it started as AI-powered enterprise search and has expanded into a full work AI platform with a generative assistant and agentic workflow capabilities. Its core value proposition is grounding enterprise AI in a company's own proprietary organizational context, enabling best-in-class retrieval and synthesis across all connected SaaS tools.
