Glean
AI-Powered Enterprise Search, Assistant, and Agents for Work
by Glean Technologies, Inc. · Palo Alto, California, USA · Founded 2019
What is Glean?
Glean is an AI workplace search and assistant that pulls together search, conversational assistant and autonomous agents to give employees a single, permission-aware view of company knowledge.
Built by former Google search engineers, Glean connects to 100+ enterprise systems including Slack, Google Drive, Notion and Salesforce to index documents, conversations and metadata while enforcing live access permissions so users only see what they're authorized to access.
It suits mid-size to large organizations that need centralized knowledge discovery and task automation, offering conversational search queries, AI-generated content grounded in your organization's data, and configurable agents to automate follow-ups or routine workflows.
Pricing is contact-only and positioned for enterprise deployments, which means onboarding typically involves IT and professional services; smaller teams may find costs and setup work prohibitive.
Performance depends heavily on connector coverage and source-data cleanliness — Glean surfaces relevant matches quickly, but it won't magically fix poor tagging or fragmented knowledge without governance. As of 2026 it is adding new connectors.
