About Glean

Glean builds AI-powered search and assistant products designed for the enterprise, providing a single interface where employees can search across all connected systems — email, documents, Slack messages, CRM records, code repositories, ticketing systems, and more — and receive AI-synthesised answers with citations. Unlike generic AI tools, Glean's foundational design principle is strict permission enforcement: it never surfaces content to a user that they could not access through native system permissions. The platform combines a powerful work graph — a real-time knowledge graph of people, content, and relationships across the organisation — with LLM-powered synthesis to deliver contextually relevant answers. Glean Agents extends this capability to autonomous, multi-step tasks such as onboarding new employees, drafting proposals, or answering complex cross-system queries automatically. The platform integrates with over 100 enterprise applications including Google Workspace, Microsoft 365, Salesforce, ServiceNow, Workday, GitHub, Jira, and Confluence. Glean's security architecture is designed for regulated industries: it maintains SOC 2 Type II certification, HIPAA compliance (BAA available), and GDPR compliance with DPA support. Data residency options are available for regulated industries, and the platform supports zero-trust architecture with granular role-based access controls, comprehensive audit logs, and real-time permission enforcement that reflects changes in source systems. Glean does not use customer data to train its foundational models. Glean was founded in 2019 in Palo Alto by Arvind Jain (former Google Distinguished Engineer) and a team of former Google, Facebook, and Rubrik engineers. The company raised a $150 million Series F at a $7.2 billion valuation in June 2025, bringing total funding to approximately $765 million with investors including Sequoia, Lightspeed, General Catalyst, Kleiner Perkins, and Capital One Ventures. Pricing is enterprise-only with custom quotes; typical reported starting points are approximately $50/user/month with a minimum of 100 seats. Smaller organisations should evaluate whether the cost and integration complexity is proportionate to their knowledge management needs, as Glean is predominantly oriented towards mid-to-large enterprises with complex multi-system environments.
